I build products people actually use — from real-time AI voice systems to platforms serving thousands of students.

THE REAL-WORLD IMPACT.
Everything on my desk and dock
Ideas are a start.
This is the work.
From the data underneath
to the page people finally see.
A few things I’ve helped bring to life.

BunkToBrains
Study platform for GGSIPU students — 4,000+ active, 7,000+ at exam peak, ₹2 Lakh+ revenue. Anti-piracy PDF and video streaming with device fingerprinting and single-session enforcement, Razorpay with HMAC-verified webhooks, and a move from Vercel to self-hosted Docker on DigitalOcean.
Hotel Explorer
One REST API over 8+ luxury suppliers — Four Seasons, Mandarin Oriental, Expedia, Accor and more. Reverse-engineered undocumented provider APIs and built resumable crawlers: 900+ properties, 50,000+ records across 25 tables.

Pulse 112
AI emergency dispatch with real-time voice triage and emotion analysis at sub-second latency — Hume AI flags caller distress, Mappls routes the nearest unit. Built to cut initial triage time by 40%.

GramUdyam Saathi
Voice-first loan advisor for first-time rural entrepreneurs under MoSJE schemes. Twelve questions in Hindi or English, then a right-sized loan — deterministic engines for scheme routing, amortisation, DSCR, catchment feasibility and a 1,000-run Monte Carlo, plus VLE and officer dashboards.

CredFlow
A drive that pays creators. Upload files, list them on a marketplace and earn via x402 crypto micropayments — with a GPT-4 assistant for creating content and AI agents that can discover and buy it.

BrickByte
Fractional real-estate investing on Ethereum — properties tokenised as NFTs from $100, with staking and an AI price-prediction model at 75% accuracy.

VectorCinema
Semantic movie recommendations — describe a mood, get films. Sentence-BERT embeddings in Astra DB, 94% precision@10.
How I work.
From idea to impact.
Choose a discipline. Follow the thinking.
- 01Find the real need
- 02Design the data
- 03Ship and iterate
From schema to checkout to the page students open at 2 a.m. before an exam — I build and run the entire thing.
Next.js · React · TypeScript · Node.js · PostgreSQL / Supabase · Tailwind
Speech-to-speech agents, semantic search and vision — engineered for latency, cost and reliability, not demos.
OpenAI Realtime · LangChain · Sentence-BERT · Gemini · Hume AI · FastAPI
Undocumented APIs, payment gateways, CDNs and self-hosted infra — the unglamorous parts that decide whether it holds.
Docker · DigitalOcean · Cloudflare · Bunny.net · AWS · Razorpay · Solidity
Scale is a number.
Efficiency is the craft.
LLM calls per conversation.
47% more data captured.
At VARA5 I built a real-time voice personalization engine on OpenAI Realtime that turns natural conversation into confidence-scored guest profiles — then re-architected extraction into a single end-of-call pass.
Weekly API requests
Served from self-hosted Docker on DigitalOcean across Supabase Postgres, Auth and Realtime.
Database load removed
Schema and query work that cleared a 1,200+ req/min bottleneck during exam season.
Production scenarios, byte-identical
Led the migration of a 20,000-line legacy commission platform to React with a zero-drift live cutover.
Build something useful.
Make it hold under load.
Give it room to grow.
Built in a weekend.
Judged by a room.
Ten wins, one trophy shelf,
and a lot of 4 a.m. deploys.








Started with code.
Kept asking why.
Started the B.Tech.
Computer Science at Guru Gobind Singh Indraprastha University, New Delhi — CGPA 8.5.
Ten hackathon wins.
Across DTU, USAR, Bennett, VIPS and Amity — ₹84,000+ in prizes, 20+ juniors mentored, and a GeeksForGeeks sponsorship secured.
Junior AI Developer, Rabbitt AI.
Semantic recommendations with Sentence-BERT, a Gemini vision assistant, real-time map tracking, and Dockerised FastAPI + Next.js services.
Full-Stack Developer, BunkToBrains.
Built and scaled the platform to 7,000+ peak students and ₹2 Lakh+ revenue, then moved it onto self-hosted infrastructure.
Technical Intern, VARA5.
Voice personalization engine, the Hotel Explorer supplier platform, and a zero-drift React migration of a legacy finance tool.
Graduating 2027.
Looking for ambitious teams building products where AI, data and real users meet.
