Full-stack AI & ML engineer who likes shipping - from training and serving models (GRPO on AMD MI300X, vision-language RAG) to the full-stack apps and infra around them. 9x hackathon podiums, two startups, and GitMesh - a Linux Foundation (LFDT) project I maintain.

About

I build because I can't not - give me a hard problem and a weekend and I'll have something running. That took me from a static HTML site in 2019 to fine-tuning LLMs on AMD MI300X and shipping production AI that holds up under real traffic and messy data. Along the way: 9 hackathon wins, two startups, and GitMesh - an LFDT AI-agent governance project I maintain. Now focused on full-stack AI and AI-infra - turning demos into systems people depend on.

Where It Started

In 2019 I shipped my first website - a static hotel landing page with responsive layout, a mobile side nav, and vanilla JavaScript (still on GitHub as first-website). No framework, no backend - just HTML, CSS, and curiosity. That foundation is the through-line to today: PARAM on Base Sepolia, GitGambit over the GitHub API, PM-JAY pipelines on Gemma, and a 40-minute session at OSS India 2026.

My Journey in AI

I started with a simple question at IIIT Gwalior: how do you make complex systems actually work? That curiosity grew into building production AI - from military intelligence platforms to on-chain applications. Winning Smart India Hackathon 2024 with a 79%-accuracy RAG system taught me the lesson that shapes everything I build: great AI isn't fancy architectures, it's shipping systems that hold up in production.

The Infra Underneath

The part I keep coming back to is the infrastructure beneath the model. I built InferenceGym, an RL environment that treats LLM serving as a control problem - batching, KV-cache budgets, speculative decoding, prefill/decode splits - and trained a policy that beats hand-tuned heuristics. I've fine-tuned with GRPO and LoRA on AMD MI300X, deployed models as Docker Spaces on Hugging Face, and built RAG pipelines over Qdrant and FAISS. I've shipped on-chain systems too - academic credentials, a micropayment CLI - when decentralization actually earns its place. But what pulls me in is making inference fast, cheap, and reliable at scale.

From Hackathons to Production

Build fast, ship faster, iterate. Co-founding Garudex Labs taught me the gap between demo and production is where engineering happens. Whether shipping EdTech serving 50+ students or maintaining open-source tools like GitMesh, the real work is error handling, feedback loops, and making sure the system doesn't break when real users hit it.

Technical Approach

PyTorch and Transformers for the models; FastAPI and Next.js for delivery; whatever serving stack keeps latency and cost sane. I reach for smart contracts only when decentralization adds real value. Mostly I optimize for one thing: code other engineers can read, deploy, and extend - because the best system is the one that ships and keeps working when I'm not watching it.
