Need an experienced VSTO developer for dedicated projects

Both of my access-control platforms—System A (Suprema's Biostar X) and System B (dormakaba's Matrix Professional)—sit on the same Windows server and share a local MS SQL instance. Each exposes a REST API, yet today they operate in silos. I need a seamless, bi-directional integration so that any change to a person or employee record in one system is reflected in the other almost instantly. Scope of the sync • Core identity fields: name and unique ID • Credential data: RFID card number and state • Biometric assets: fingerprint templates • Media: profile picture • Security attributes: access-level permissions Key requirements 1. Real-time operation (sub-second latency acceptable). 2. Conflict-resolution logic—latest change...

I need a seasoned Power BI developer to turn a very large, highly-granular data set into a single, dynamic dashboard focused on monitoring key operational-efficiency KPIs. Here’s the landscape you will step into: our raw information sits in both SQL databases and a series of regularly exported Excel/CSV files. I want a model that connects to each source, transforms the data so that it’s truly analysis-ready, and then visualises the metrics that matter—cycle times, throughput, bottleneck alerts, utilisation rates and any supporting drill-downs we decide to add. Scope of work • Build or optimise the data model, including merge logic between SQL and CSV tables, DAX measures, and relationships that guarantee a fast, responsive user experience even when the data vol...

I need a full-stack, self-hosted .NET solution that runs a 2 × 2 matrix MLM system. The site must let new members register under a sponsor, automatically position them in the chain, and reflect spill-over earnings in real time. Core roles are Standard user, Sponsor and Admin. A registered user should see a clean dashboard that shows an earnings overview, live balance details and a searchable transaction history. From that same panel they must be able to deposit, withdraw or transfer BEP20-based USDT, with each on-chain action recorded to the ledger and mirrored instantly in the database. The admin control panel must allow me to browse every account, approve or reject any pending deposit/withdraw request, modify wallet addresses if needed, and trigger manual payouts. Every sensitive...

I’m building a new travel portal that should feel and flow almost exactly like Onetravel (about 90% of its current UX), but written end-to-end in .NET with Bootstrap so the layout stays fully responsive on every page. Core flow From Search → Listing → Detail → Add-On → Contact → Payment → Confirmation each module has to work seamlessly. For demo I need the Flight booking piece up and running before we expand to Hotel, Car, Bus and Holiday packages+ an Android app for the same Flight module must include • Search flights • Flight details page • Add-on services (bags, seats, meals, etc.) • Contact • Payment • Confimation page with Email to user • Data Saved on Google Sheets as Tables Under the hood • Mo...

I’m building a green-field product that needs a solid foundation across web, mobile and cloud. The server side will run on .NET (Core/Framework) and expose RESTful endpoints organised as micro-services. For the browser I’m happy with either Angular or React—pick whichever you are fastest with—and the companion mobile app will be written in React Native so we can share as much logic and styling as possible. The data layer can land on SQL Server, a NoSQL store or a mix of both; I’m open to your recommendation as long as the choice is justified and future-proof. Everything will be hosted on AWS or Azure, wired into a CI/CD pipeline (GitHub Actions or Azure DevOps are fine) so every commit ships automatically through test, staging and production. Clean code, SOLI...

Our live platform, built on .NET Core (MVC, C#), needs an experienced bilingual Arabic/English developer to step in on a part-time basis and keep everything running smoothly while we roll out new capabilities. The work is time-sensitive—ideally code starts moving this week—so I need someone who can plug in and contribute immediately. Scope of work The current solution spans several modules that exchange data with internal and third-party services. Typical tasks include tracing and resolving production issues, refactoring brittle sections for performance, tightening security around existing endpoints, and adding small to medium features as specifications come through. You will work against an Azure DevOps repository, create pull requests with meaningful commit messages, and d...

I’m hiring a seasoned .NET + Angular engineer who can act as a personal mentor for a friend of mine in Udaipur. She has three years of support experience in infosys and has just moved into an SDE role in different company, so she needs guided, practical coaching rather than generic tutorials. The focus is pure mentorship and guidance delivered through one-on-one video calls. During these sessions you will walk her through the tickets already assigned to her, explain the underlying concepts, review her code, and show her how to debug, refactor, write tests, and follow best practices that align with real-world enterprise workflows. Early in the engagement I’ll also need a brief, well-vetted shortlist of a few additional .NET/Angular tutors (with phone numbers) so we have backup...

I need a Windows-based typing application, built to mirror the exact pattern used in Indian government recruitment exams. The program must run smoothly in both online and offline mode so that a candidate can practise anywhere and then sit a timed test even if the internet drops. Core functionality • Practice mode stocked with graded typing exercises. • Full-length mock tests that reproduce the official exam interface, timer and font rendering. • A performance dashboard that tracks speed, accuracy and trend lines over time. Language support All content, UI prompts and result reports should work in English and Hindi from day one. If you architect the system cleanly I can add further regional languages later, so keep strings externalised. Benchmarks Speed and accur...

I need a custom Windows-compatible control panel that can automatically handle Zynga Poker chips from end to end. The core of the project is threefold: • Chip generation – the panel must reliably create chip quantities I can define on demand. • Transfer management – once generated, the chips should move between accounts smoothly, with options to schedule or batch transfers. • User account control – I have to be able to add, edit, suspend, or delete game accounts directly inside the panel. Code quality and stability matter more to me than flashy graphics, so feel free to use a lean UI framework that keeps things fast and uncomplicated. A clear dashboard, real-time status indicators, and basic logging/export will cover my day-to-day needs. You are fre...

I’m building an AI-driven web application that combines Natural Language Processing and Predictive Analytics to deliver real-time insights for end users. The stack is already defined: • Front-end: React.js • Service layer: Node.js • Core business logic: .NET (C#) microservices, Firebase • High-speed caching/pub-sub: Redis • Infrastructure & DevOps: Microsoft Azure (App Service, Functions, Container Apps, Azure SQL/Storage, and Redis Cache) Scope of work 1. Design a clean React interface that consumes RESTful and WebSocket endpoints. 2. Build scalable Node.js gateways that route traffic to .NET microservices and manage authentication/authorization. 3. Implement NLP and predictive models (Azure Cognitive Services or custom models) and exp...

I’ve already built a working medical prototype inside Google AI Studio and now I need it packaged as a true standalone Windows desktop application. The main responsibilities will be: • Re-architecting the current Google AI Studio build so it installs and runs natively on Windows without any command-line dependencies. • Designing a data layer that lets each clinic choose either a local, offline database or a secure cloud-hosted option, with an easy switch between the two. • Implementing strong security around patient records and treatment plans: encryption in transit and at rest, role-based access, and a well-structured authentication flow. • Guiding me through code signing, installer creation, and any compliance considerations typical for medical software. ...

Project Overview: We need a clean, well-documented, production-ready .NET-based ABDM integration component for our healthcare project. The solution must support ABDM/ABHA official workflows for M2 and M3 modules. Expected Functional Scope: • Integrate with official ABDM APIs for M2 (HIP) and M3 (HIU) workflows • Consume ABDM requests and callbacks correctly • On receiving ABDM data requests, query our internal healthcare database and generate the required FHIR-compliant resources/bundles • Return/share health records back to ABDM in the required format, including encryption/security requirements • Support consent-based health information exchange flows • Support ABDM gateway communication, token/auth flows, callbacks, and auditability • Design sol...

I’m building a hiring pipeline for several senior-level Software Developer roles and need a recruiter who can quickly surface the right talent. Each position demands strong, hands-on proficiency with C# and the .NET stack, so your sourcing should focus on candidates who live and breathe that ecosystem. Here’s how I picture our collaboration: • You’ll study the job description I provide, clarify any grey areas with me, then launch targeted searches across LinkedIn Recruiter, GitHub, Stack Overflow, job boards, and your own network. • Within the agreed timeframe, I expect a short-listed batch of screened résumés—people who match the must-haves on skills, seniority, location, and salary range. • For every candidate, include a concise ...

I have a collection of mature Windows automation scripts written in PowerShell and I want every bit of that logic rewritten in clean, production-ready C#. The end result should be a head-less Windows service/agent—no GUI—capable of handling all existing task-scheduling duties without requiring user interaction once installed. What you’ll be touching: • Windows internals: services, scheduled tasks, processes, file system, event logs • Registry read/write with safe rollback logic • WMI and other system-management APIs for device and OS-level operations • Packaging and deployment strategies that avoid common antivirus false positives; signed binaries are strongly preferred Scope of work 1. Analyse the current automation scripts and design an equiv...

I need a complete, working business suite that covers Accounting, Sales, Inventory, Invoicing and Personnel Payroll. You may deliver it as one integrated application or as clearly linked modules, provided every part runs reliably on its own and shares data smoothly. Accepted languages are Python, C or Visual Basic .NET—choose whichever you already master. What matters most is that you hand over the full, well-commented source code, a sample database, and clear build/run instructions so I can compile or execute everything on a Windows machine without extra troubleshooting. Typical flows should work out of the box: inventory updates after a purchase, receivables after a sale, payroll entries posting to the ledger, plus standard reports such as trial balance, income statement, stock...

I already send messages from my web-based application through the Meta WhatsApp Business Cloud API, but what I am still missing is a reliable feedback loop. Whenever I blast, say, 1,000 messages I need my software—an ASP.NET site running on SQL Server—to receive the delivery receipts and failure notices automatically, without anyone logging in to the Facebook/WhatsApp dashboard. The job is straightforward: • Create and expose a secure webhook endpoint in C# (ASP.NET). • Complete the verification handshake with Meta and subscribe to message-status events. • Parse each incoming callback, identify the phone number and status (delivered, failed, etc.), and write it into the tables that already exist in my SQL Server database. • Return a simple success re...

I manage both Indian wedding shoots and post-production for American clients, so dozens of events, photographers, editors, invoices, and deadlines move through my hands at once. At the moment everything lives in a sprawling Excel file that my manager updates, but scrolling through rows is slowing us down. I want that spreadsheet converted into a clean, purpose-built desktop application that runs natively on Windows and Mac. What the app must do • Create a job card with client details, shoot date, assigned team members, and promised delivery date. • Let us update team status in real time—who’s shooting, who’s editing, who’s designing albums—so I can see bottlenecks at a glance. • Track every deliverable (footage, edited photos, highlight f...
