CS undergrad. Full-stack builder. I make things that work and things that feel good.
5th sem IT student from Kolkata. I build full-stack applications — backends that scale, frontends that look good.
Recently: built a voice-first "Ambient Intelligence" system for retail stores (DataTalk AI) which ranked in top 50 nationwide, built PayPal Pact (an autonomous AI-arbitrated escrow platform using PayPal's AUTHORIZE intent & Celery), architected a KIVI-inspired INT8 KV cache quantization engine in PyTorch (reducing GPT-2 footprint by 68.5%), shipped Ninja Tag (a real-time 1v1 multiplayer browser game using WebSockets), and co-built a CTF site for IEEE TechWeek.
A selection of projects that showcase my skills and creativity
Voice-first "Ambient Intelligence" system for Kirana stores. It captures shop activity via voice + camera feed, converting real-world retail interactions into structured business intelligence. Automates billing, generates real-time insights, and tracks inventory with zero manual data entry. Built with Azure Multimodal Fusion as part of Team RunTime Terror.
Architected a secure, autonomous escrow platform integrating a Celery-driven LLM verification pipeline and PayPal webhooks to execute atomic financial settlements based on deterministic payload validation, adversarial prompt defenses, and a tamper-proof audit ledger.
Architected a custom inference engine in PyTorch with a KIVI-inspired INT8 quantization pipeline,
bypassing model.generate() for manual token-by-token cache management.
Reduced GPT-2 KV cache footprint by 68.5% with only a 0.71% increase in perplexity, implementing flexible
symmetric/asymmetric quantization schemes across whole-tensor, per-channel, and per-token granularities.
Real-time 1v1 multiplayer browser game with room-based matchmaking. Implemented 60 Hz client prediction and server reconciliation with sequenced inputs, ACKs, and deterministic movement. Engineered a fixed-timestep 20 Hz authoritative server with room isolation, input validation, and automated integration tests.
Co-built a multi-challenge CTF event site for IEEE Manipal's TechWeek as part of a 5-person team. I implemented multiple clues including the dystopian bookshelf puzzle (an immersive drag-drop challenge) and the audio steganography clue, where hidden messages were encoded in spectrograms and surfaced only through developer tools.
Selected for the Top 50 Prototype League out of 300+ teams nationwide with DataTalk AI.
I'm open to internships, collaborations, and interesting problems.
