Vipin Gupta

I’m a full-stack developer (MERN) who focuses on building secure, user-friendly web products—from marketplace workflows to real-time dashboards. I enjoy turning complex requirements into clean, reliable experiences that users can trust.

In my SkillSphere Marketplace work, I architected a full-stack hyperlocal freelancing marketplace with proximity-based gig discovery using the HTML5 Geolocation API. I also implemented a secure, multi-role escrow wallet payment flow with React.js, Node.js, Express.js, Socket.io, FastAPI, Bootstrap, and Chart.js, using transaction ledgers to ensure clients are debited on bid approval and freelancers are paid on milestone completion.

I build with real-time thinking too—using WebSockets for bi-directional messaging with persistent history in MongoDB—plus dynamic rating and client feedback aggregations. Alongside that, I’ve developed a Binance Futures Trading Bot with Python/FastAPI and cryptography for automated REST BUY/SELL execution, and created billing/landing experiences like BillCraftStudio and a responsive A8TigerFitness Gym site using WhatsApp API for automated lead generation.
