Biswajeet Sahoo

I’m a Full-Stack Developer with 2+ years of experience building full-scale web and mobile applications. I’ve built and maintained high-throughput APIs for 10,000+ users, integrated cross-platform in-app purchase systems, and launched an Android app with 500+ downloads and a 4.9 rating.

In my current role at Avadhuta Technologies, I designed a centralized, event-driven notification system using Redis Queue and N8N to enable asynchronous, scalable multi-channel delivery. I also implemented Razorpay webhook-driven reconciliation to achieve 99.9% payment success and real-time subscription updates, while building secure authentication and authorization using OAuth 2.0 and JWT refresh-token strategy and role-based access control across 5+ permission tiers.

I’m equally focused on performance and reliability: I reduced app load time by 40%, improved page load from 2.5s to 1.0s with server-side rendering and optimized data fetching in Next.js, and tuned GraphQL queries to eliminate over-fetching. On the mobile side, I delivered recording and playback in React Native (audio up to 6MB) with optimized buffering, and I’ve built real-time SOS alerting and location-based emergency response features during my internship with strong crash-free results across 50+ Android devices.
