API Development is an effective way for software to communicate and interact with each other over the internet. It’s a great way for developers to expand the capabilities of a program or systems by creating interfaces and allow data to be shared between different types of technology. With an API, existing systems can connect and more advanced solutions can be made. Hiring an API Developer can enable businesses to streamline processes and enable a much faster integration of existing software solutions.

Tenho um ERP consolidado e um CRM ativo, mas eles ainda trabalham como ilhas. Quero que as duas plataformas conversem de forma transparente para que o processamento de pedidos e toda a gestão de relacionamento com clientes aconteçam em um fluxo único, sem retrabalho ou troca manual de planilhas. Procuro alguém que pense a arquitetura de ponta a ponta: levantamento das APIs ou conectores disponíveis, desenho do fluxo de dados em tempo real (ou quase), definição de middlewares, filas de mensagens ou ESB se fizer sentido, mapeamento de campos e políticas de autenticação / segurança. Valorizo propostas que considerem escalabilidade e monitoramento desde o início, porque o volume de transações de ...
I’m running a self-hosted Odoo v17 instance and I want it to speak with Claude in a strictly controlled, read-only fashion. The goal is for Claude to pull customer-relationship data, inventory figures and any other information needed to generate automated reports—nothing more, no write or admin rights at all. Security is paramount, so I’m open to whichever connection method (API, webhooks, or another highly secure approach you can justify) best keeps the data safe while remaining maintainable with future Odoo and Claude updates. You’ll need to map the relevant Odoo models, handle authentication, and make sure permission scopes remain locked to read-only. Deliverables should include: • A working integration module or middleware script fully installed on my s...
I need a full-stack developer who can design and code a streamlined, custom CRM that covers the entire sales funnel for my real-estate team. The platform must excel at the three core functions I rely on most—lead ingestion and syncing, AI WhatsApp follow-up, and a clear analytics dashboard—while capturing every key data point: contact details, property preferences, and each buyer’s timeline and budget. Lead ingestion & database Every new prospect coming from Meta Lead Ads (Facebook and Instagram) should flow automatically into a central database. I picture an Excel/Google-Sheets style grid where my agents can filter, sort, or bulk-edit records without touching the back end. Reliability and near-real-time syncing are non-negotiable. AI WhatsApp follow-up The mome...
I need a lightweight .NET service that communicates with Epicor’s REST API and keeps our database and the ERP in lock-step. The core requirement is real-time data synchronization—changes made in either system should be reflected in the other within seconds, without manual intervention or batch jobs. Beyond simply moving records back and forth, the service must apply custom business logic before any write is committed. That logic includes: • Processing transactions – e.g., auto-generating related records, updating status fields, and posting to the correct Epicor endpoints. • Data validation – rejecting or flagging incomplete or incorrectly formatted payloads so we never pollute Epicor with bad data. • Workflow automation – triggering follow...
I am building a full-featured mobile marketplace that runs smoothly on both iOS and Android. The app will present two completely separate experiences: one dashboard for customers and another for sellers. Core experience • Customers and sellers can each create listings, upload multiple photos, and have every image automatically scanned and sorted into the correct category so products stay organized without extra effort. • A real-time chat layer lets the two parties negotiate, share more images, and finalise details inside the app. • Push notifications will alert users to new messages, offer updates, and deal milestones. • Every transaction—from first contact through payment confirmation—must be logged so that both parties can review their full deal histo...
I need my Shopify checkout to pull live shipping costs from my logistics partner’s API and pass the final amount through Razorpay before the customer completes payment. The API documentation is already in hand, so you can dive straight into development without hunting for specs. Here’s the flow I want: • Customer enters their address → API returns location-based shipping options → a preliminary estimate appears in the cart or first checkout screen. • On the payment step, the script calls the API again (or confirms the earlier call) to lock in the exact charge, adds it to the order total, and hands everything off to Razorpay for collection. Key requirements • Custom rule: rates vary only by delivery location; weight or size don’t matter...

'd like to improve the Quick Number Click feature. At the moment, if a student leaves the course or changes to another class/day, I have to manually renumber everyone, which is time-consuming. I'd like the numbering to become dynamic, so I can easily reorganize students without editing each number manually. Requirements Move Student Allow me to move a student from one position to another. Example: Move student from position 12 to position 5. Students currently in positions 5–11 should automatically shift down one position. The numbering should always remain sequential. Insert Student When adding a new student, allow me to choose the desired position. Example: Insert a new student at position 8. Current students from position 8 onward should automatically move down one pos...
I have a mature JavaScript / Node.js codebase that now needs robust API connectivity. The goal is to wire in several external services—some exposed as classic REST endpoints, others as GraphQL—so the application can consume, transform, and surface that data seamlessly to the front-end. Here’s what I need from you: • Analyse the existing structure, identify the best touch-points for new service layers, and keep everything idiomatic to Node.js (Express, middleware, async/await). • Build out the integration layer for both REST and GraphQL calls, including token management, retries, and intelligent error handling. • Return clean, typed responses (TypeScript definitions or JSDoc) so downstream modules stay type-safe. • Write concise unit and integr...

My MERN-based medical platform is already feature-complete and sitting in a private Git repo; only a round of QA fixes stands between it and production. I now need a solid full-stack team that can step in, close every open bug, harden the code, and drive the app all the way through staging, UAT and live deployment (Docker + CI/CD to the cloud is preferred). The bigger challenge is an add-on “analyzer” service. Its sole purpose is to pull raw readings directly from laboratory analyzers and inject them into our existing test-result flow—essentially automating what is still a manual entry step. • Type of processing: the analyzer’s job is “taking data from Analyzers into the test result” pipeline; no further statistical or predictive crunching is re...

Certification Program Management Platform — Partially Built, Looking to Complete I am building a web platform to manage a multi-step applicant certification process from start to finish. A solid working prototype already exists and I need an experienced developer to take it to production. The workflow: Applicant receives a unique link → completes an application → acknowledges program rights and signs digitally → uploads ID documents via desktop or mobile → takes a 199-question online exam (80% to pass, with study and retry mode) → completes an in-person assessment recorded by admin → system generates all required program documents in a single applicant file.

AI Agent Platform (Build Brief) About us HOTR is a creator management agency. We manage a roster of 15–19 digital content creators (£100k–137k/month gross) with a team of ~15 (operations, customer support, marketing, a ~10-person messaging team, and finance). We want our own private, cloud-hosted AI assistant for the agency — built on our infrastructure, owned entirely by us. What we need (v1 scope) A web-based chat bot with two specialist AI agents: 1. Acquisition agent Helps run our creator-signing pipeline: Track prospects and their stage (contacted → pitch sent → follow-up → signed / lost) Flag stalled leads (our biggest leak: prospects go cold after the pitch with no follow-up) Draft outreach and follow-up messages in our tone of voice Answer ...
I’m kicking off a green-field web application for D Daya AI and need a full-stack partner who can take the idea from wireframe to deployable product. The build starts from scratch, so you’ll own both the front-end experience and the back-end logic.

You’re free to propose the stack that best fits those goals—React, Vue, Angular on the front, Node, Django, or another performant back-end are all welcome as long as the final codebase is modular, well-documented, and easy for an internal team to maintain. Deliverables • ...
I already have a clean, responsive front-end for my travel-insurance booking site; now I need the complete engine behind it. Your job is to architect and code the full back-end layer, expose well-structured REST APIs, and wire everything to Indian payment gateways. Core scope • Build the entire server-side infrastructure — database schema, business logic and API endpoints — so that users can browse plans, generate quotes, buy a policy and download documents. • Create an admin module view transactions and run simple reports. • Integrate payment gateway(s) and complete payment in INR.

I run a Shopify-based store and need a purpose-built application that keeps my inventory accurate without constant manual checks. The core of the job is to engineer a lightweight system that: • Pulls item quantities from Shopify in real time and displays them in a clean dashboard • Triggers automatic reorder alerts when any SKU hits the threshold I set • Generates clear, exportable sales and inventory reports so I can spot trends quickly The software has to connect directly through Shopify’s latest API, handle variants, and remain responsive even as the catalog grows. A simple browser interface (or an Electron desktop app) is fine as long as it is intuitive and works on Mac and Windows. Please outline: – Your proposed tech stack and why it suits Shopify&...
I want to stand up a dedicated image-hosting platform that I fully control rather than relying on third-party services. The core requirement is the ability to upload, store, and deliver images quickly and reliably at any resolution, with clean URLs and no branding except my own. Here’s what I have in mind: • A modern, responsive front-end where users can drag-and-drop or batch-upload images, see instant thumbnails, and copy shareable links. • A solid back-end—Laravel, Node, Django, or a stack you’re comfortable with—that saves original files, generates multiple sizes on the fly, and serves them through a CDN or bucket-style storage to keep latency low. • An admin panel where I can monitor storage usage, purge content, and toggle simple settings ...
I need an experienced Boomi developer who can take charge of three live integrations in a single sprint. First, you will handle our Oracle workloads: a one-time data migration from legacy tables into the new schema, followed by reusable custom API connections that expose key endpoints to Boomi. Next, you will wire Salesforce to Boomi so that Sales Automation events and Marketing Campaign objects flow bi-directionally with minimal latency. Finally, you will connect NetSuite for order-processing—new orders initiated in Salesforce must create, update, and close the corresponding transactions in NetSuite automatically. Deliverables • Boomi process designs, deployed and working in DEV, TEST, and PROD • Parameterised connectors for Oracle data migration and custom...
I need a Meta-qualified specialist to make sure every lead my ads generate is captured accurately. My account already runs campaigns, but I’m uncertain whether the Custom Conversions are configured at all. The site itself is custom-built, so there is no plug-and-play app; you’ll have to implement the Meta Pixel and Conversion API directly (GTM, server-side script, or a lightweight node/PHP endpoint—whatever you recommend). The only event I care about right now is a Lead Form Submission. Once the tracking is in place I want it verified inside Events Manager, sent through the Pixel Helper and the Test Events tool, and then observed in a live campaign for a day or two just to confirm real-time firing and deduplication. No creative tweaks, bids, or optimisation work are req...

I’m building a comprehensive marketplace that lets patients book clinic visits with verified doctors, nurses, caregivers, physiotherapists, and other licensed professionals. Each practitioner will have a profile where they can upload credentials, describe services, set their own fees, and update real-time availability. Patients must be able to search using the filters we care about most—specialty, location, price, rating, and preferred language—then reserve an in-clinic appointment in just a few taps. (Video consultations and home-care bookings will follow, so keep the architecture flexible for those additions.) Every patient account will include an encrypted medical file that stores reports, prescriptions, allergies, medications, surgical history, and ongoing treat...

To access the full suite of features offered by the SBI Digital Rupee application, there are specific eligibility requirements. Primarily, the service is available to individual customers who hold an active savings account with the State Bank of India. During the registration process, the app will verify your identity using the mobile number registered with the bank. It is essential that the SIM card of the registered mobile number is present in the device you are using for the app, as the system uses SIM-binding for enhanced security. For the "Full-KYC" wallet, you will need your SBI account number and your SBI Debit Card details to authenticate the setup. The debit card is used to verify that you are the legitimate owner of the account before the wallet is linked. For those wh...
I have a custom data source that needs to feed seamlessly into HubSpot. Once the API connection is live, I want all relevant Marketing Metrics—think campaign performance, lead source attribution, channel ROI—to flow straight into HubSpot’s Reporting and Analytics module without manual exports or spreadsheet wrangling. Scope of work • Build or refine the API connection so data syncs reliably with HubSpot in real time. • Configure automated dashboards and scheduled reports inside HubSpot that surface the marketing KPIs I rely on. • Ensure the setup is scalable; future metrics or additional objects should be easy to map and pull in. • Provide concise documentation so I can adjust filters or add fields later without starting from scratch. Accepta...
I’m putting together a modern, responsive application that must feel effortless on both desktop and mobile screens. My top priority is user experience and design, with intuitive navigation sitting at the very heart of the project. I still need the full stack: a clean, component-based front-end, a secure and scalable back-end, solid database integration, and well-structured APIs. Performance, security, and maintainability all matter, but only if they serve a beautiful, friction-free interface. Here’s what I need from you: • A brief overview of projects where you have owned both UI/UX and the underlying architecture. • The tech stack you propose and why you feel it fits the goal of a fast, responsive, user-driven product. • An estimated timeline that includes...

Businesses spend ₹50K–₹2L/month on Meta and Google ads. The leads arrive on WhatsApp. Then they rot — nobody replies at 9pm, follow-up is a receptionist with a notebook, and most enquiries never become appointments. We connect their ad accounts and their existing WhatsApp number, qualify inbound clients with an AI loop, book them into the calendar, chase the confirmation, track who actually showed up, and report the outcome back to the business— and back to Meta, so the ad algo...
I’m building an end-to-end conversational AI that handles text and real-time voice in four languages, guides users through staged enquiry and reservation flows, and syncs seamlessly with our existing systems and website. The core must expose a secure WebSocket API for live messaging, catalog synchronisation, and remote-tool protocols so my in-house apps can push or pull data without lag. Front-of-house, I need a portal-grade web stack: server-side rendered pages, a multilingual CMS, and a media pipeline that keeps images and audio optimised across devices. Back-of-house, the platform has to talk to the channels where our customers already are. For this phase I want native connectors for LINE OA, WhatsApp Business, Facebook Messenger, Telegram, Instagram, Google Business, TikTok, and...
I’m ready to commission a complete Flutter-based Android application that helps students prepare for competitive exams.

I need a streamlined, cloud-based inventory management system that gives me an up-to-the-second view of stock across all locations. The core of the build is real-time inventory tracking tied to automated reorder alerts so that low-stock items trigger a purchase order or notification immediately. Flexible threshold settings and simple user permission controls must be baked in from the start. A clean, browser-based interface is preferred, but I’m open to a lightweight desktop or hybrid approach if it keeps performance snappy. Although barcode scanning is not a priority for the first release, I’d like the architecture to leave room to plug that in later without a major rewrite. Deliverables • Fully functional inventory application (front end + back end) with real-time stock...
