Who I am?

HI THERE, I'M ARNAB PRAMANIK. I am a product-obsessed full-stack engineer and student at IIT Dhanbad who thrives on taking ideas from zero to one. While I have the algorithmic foundation to whiteboard scalable architectures and build high-throughput microservices, my true focus is on extreme ownership, rapid iteration, and shipping pragmatic MVPs. I thrive in chaotic, fast-paced startup environments where I can solve tricky technical bottlenecks and build polished user experiences that actually solve business problems.

GoTypeScriptDart

Architected an event-driven esports platform and career marketplace. Engineered a decoupled Go and AWS (SQS/SNS) microservices backend processing 100,000+ daily events and handling 10,000+ concurrent connections with strictly <50ms latency.

GoTypeScriptNext.jsPythonWebGL

Architected a comprehensive Hybrid-EdTech platform featuring procedural 3D musical notation and advanced user analytics. Built as a monorepo containing a Next.js/React web client, a mobile app, and a robust microservices backend written in Go (auth, api-gateway, library, plan, social).

Autonomous Revenue Recovery Ecosystem

Autonomous Revenue Recovery Ecosystem

GoPythonTypeScriptNext.js 14FastAPI

India processes 14 billion digital transactions every month — 1.4 billion of them fail. Every payment gateway reduces these to one lazy word: FAILED. This system disagrees. Built across 13 containerized microservices in Go, Python, and Next.js 14, it classifies every failure in under 15ms across 100+ raw bank clearing codes, then dispatches the mathematically correct recovery — a deterministic NACH mandate shield that lifted revenue +51.3% over blind retries, a causal uplift engine that suppresses discounts when margins don't justify intervention, Indian statutory tax law encoded as a live B2B collections engine, and a chargeback defense pipeline with VAMP ratio protection. Not a feature. A complete, production-grade autonomous financial immune system for Indian payments.
