Abhinav Das

I’m a backend-focused software engineer building scalable full-stack systems with the MERN stack, RESTful APIs, and containerized deployments. I combine strong DSA and systems programming foundations with practical experience in authentication design, database modeling, and real-time architectures. In my current project, CodeSync, I built a browser-based real-time collaborative IDE with multi-user editing using Yjs CRDT and Socket.io. I designed a modular backend across 11 feature modules and integrated Judge0 for 50+ language code execution and Ollama for AI-assisted inline editing. I also built an AI-Powered Interview Coach that uses OCR-based resume parsing with 85% text-extraction accuracy, along with JWT-authenticated REST APIs. Deployment efficiency improved by 15% through Docker containerization, and I reduced login processing time by 12% with streamlined session management. Beyond web development, I’ve worked on embedded systems through TinyUNO, where I built a custom bootloader for ATmega328P using cooperative multitasking to reduce memory footprint by 18%. I bring the same engineering rigor to research and leadership, including patent research on RFID-based elevator optimization and co-leading Bengali literary events.
