Project Overview I'm building RailWise AI — a web app that helps Indian train travellers find the most reliable route to their destination, not just a ticket. The core idea: instead of just showing train options, we score every journey from 0–100 based on confirmation probability, delay risk, transfer risk, and cost. Think of it as a reliability engine on top of Indian Railways data. What needs to be built (MVP only — keep it simple) A simple web interface where user enters source station and destination station Backend fetches available train options by scraping (availability data) A scoring engine that calculates a Reliability Score (0–100) for each journey option based on logic I will provide in full detail (already documented) Results page showing top 3...

Our real-time data platform needs a rock-solid proxy layer that can move huge volumes of HTTP and SOCKS5 traffic with minimal latency.

Developer Needed – Lean MVP Build for Marketplace Startup (Circulate) Project Overview I’m building a startup called Circulate. Circulate is a local marketplace platform where users trade goods and services using an internal credit wallet system instead of cash.

I want to use existing integrations/services wherever practical to keep development time and costs low. ________________________________________ Core Concept Users trade using internal platform credits instead of cash. Rules: • every user starts at 0 credits • users can spend down to a controlled negative balance (exam...

I have a fully-functional codebase that combines a front-end, an Express API, and Prisma for data access. Everything runs correctly on my machine, but it still lives only in development. I now need it deployed to production using the stack I have already chosen: on Vercel, the Express server on Railway, and an existing Supabase Postgres instance. The database is set up and populated, so there is no migration work required. What I do need is the entire deployment workflow put in place, along with any environment-variable wiring I may have missed. I can provide the actual secrets; I just need clarity on what must be set where so that the front-end talks to the API and the API talks to Supabase through Prisma. Deliverables • Live, publicly accessible site on Vercel • Expres...

I need a developer to add a brand-new payment option to my Shopify checkout that routes transactions through Fygaro Link using a JWT flow. The store already accepts PayPal, Stripe and Shopify Payments, but this new gateway must operate as a fully custom method and coexist seamlessly with the existing ones.

I need a hands-off way to pull data from my Housecall Pro CRM, run it through ChatGPT for on-the-fly analysis, and push the results into a live dashboard that blends charts and tables. Currently, I believe that this can only be done with Zapier. The goal is to see all key performance indicators at a glance—sales, operational, marketing, financials without exporting a CSV again. Here’s how I picture it working: an automated script (Python, Node.js, or whatever language you’re most comfortable with) calls the Housecall Pro API on a schedule I can adjust. Raw data is cleaned, ChatGPT summarises insights or flags anomalies, and everything feeds straight into a front-end dashboard—Think Looker Studio, Power BI, or a lightweight custom web page—using a mixed layou...

Accessibility and mobile responsiveness are non-negotiable. On the backend you’ll create well-structured Node.js services that expose RESTful APIs, connect to our existing data sources, and handle integrations such as CRM and email gateways. I&r...
