Profile

The short version

I build AI systems that actually ship — owning every layer from data pipeline and ML model to API and interface. Most of them built in days, not months.

I’m a full-stack developer and AI/ML engineer with 2+ years of production experience. I’ve shipped deterministic risk engines, hybrid-retrieval RAG, on-device vision systems, agentic fintech copilots and full-stack products — comfortable owning a feature from raw data all the way to a polished UI.

Currently in my B.Tech in Computer Engineering (2023–2027), winner of the Nirman 2026 hackathon, runner-up at the Sigma Squad × BIS hackathon, with memory-safety patches merged upstream into libheif and assimp. I like problems that are hard, deadlines that are tight, and software that earns its place.

Trinetra

Compound-Risk Intelligence for Industrial Safety

A deterministic risk engine that fuses gas sensors, hot-work permits, CCTV and shift logs into one real-time brain — catching the lethal combinations every individual safety system rates as acceptable. LangGraph agents explain each alert; they never decide it. Replayed against real disasters, it fires minutes before any single sensor.

NAADI

MSME Financial Health Card & Underwriting Copilot

A financial health card for businesses the balance sheet never sees. GST, UPI, Account-Aggregator and EPFO rails feed a monotone LightGBM scorecard with TreeSHAP reason codes and counterfactual comeback paths, while an agentic copilot drafts the full sanction memo — the LLM writes prose, the engine writes every number.

RegSutra

From Circular to Code — Agentic Compliance Engine

An agentic compliance engine for SEBI's rulebook. Six staged agents turn a regulatory circular into a typed, machine-actionable obligation graph in about 12 seconds — every artefact grounded in its verbatim clause, every action sealed into a tamper-evident SHA-256 hash chain a regulator can verify.

StorePilot

The AI Store Manager for Small Retailers

Born from selling POS systems to exactly these shops. It reads sales and stock every morning, briefs the owner on the three things that need doing, and drafts the messages that do them. GPT-5.6 narrates over an agentic tool loop with evidence chips — deterministic, tested math does all the calculating.

FaceAttend

Offline Face Recognition & Liveness Detection

Face authentication for remote sites where the internet doesn't reach. MobileFaceNet embeddings run fully on-device inside a camera frame processor, behind random blink–smile–turn liveness challenges a photo can't pass — with an offline-first queue that syncs the moment a network returns.
