About Me

I'm Shiva, an Applied AI Engineer. Got into coding in 9th grade, spent a few years doing freelance work with PHP and jQuery before landing on React. The project that taught me the most was Animetrix, an anime streaming site I built in college that hit 15k users and 200 GitHub stars . It was technically piracy (I was naive), broke constantly under traffic, which taught me about scalability. I rewrote the infra from scratch and got it to handle 20k users, picking up Redis, Docker, horizontal scaling, and YAML along the way. Eventually got DMCA'd. Worth it.

Won 5 hackathons, including qualifying for Smart India Hackathon 2023 in my first semester, first from my college with roughly a ~1% selection rate. Since then I've shipped production AI systems at a few early-stage startups. One of them I joined as a founding engineer, where I got deep into fine-tuning LLMs on low-resource Indian languages using Unsloth, containerizing models with Docker, self-hosting on servers, and exposing them as public APIs. Right now I'm working at Bez, building an AI copilot for jewellery designers — where I get to work with AI agent workflows, vector search, RAG-based memory, and multimodal image pipelines.

Notable achievements

• Smart India Hackathon. Made it to SIH 2023 in my very first semester of college. Didn't really know what I was doing but figured it out.
• Hackathons. Won 5 hackathons, mostly building AI stuff. WasteEasy was probably the one I'm proudest of, a full waste-management app that uses AI-assisted waste classification, nearby disposal discovery, and a rewards loop where users earn coupons for responsible dumping. Took home Rs. 30,000 from ADTU and got called out as a unique tech startup at an IIM Shillong entrepreneurship event.WasteEasy on GitHub
• Rise In bounty. Got a bounty from Rise In for a project that lets people lend money on Ethereum and build an actual credit score on-chain. Built flows for issuing loans, tracking active borrows, repayments, and defaulter marking with transparent contract-backed state. No banks, just smart contracts.lending-blockchain on GitHub
• In the news. Got featured in a national newspaper for building a fine-tuned LLM on the Assamese language, one of the first of its kind for a low-resource Indian language.
• Side project at scale. Built AnimeTrix, an anime streaming site, hit around 15,000 users and was handling 100 concurrent viewers at peak using web scraping and some creative infra decisions. Had to take it down after a DMCA. The repo still has ~190 stars.AnimeTrix on GitHub
