About Me

I'm Shiva, an Applied AI Engineer who learned by building things in public, breaking them under real users, and then fixing the parts that failed. I started with freelance PHP/jQuery work, moved into React and full-stack systems, and eventually found my lane around applied AI, infra, and product engineering.

The work that taught me the most came from building web streaming projects — wiring up HLS / m3u8 pipelines, scrapers, caching layers, and servers that had to hold up under 15k users. It was chaotic and forced me to learn scaling, infra, and the painful side of shipping fast — still one of my best technical lessons.

Since then I've won 5 hackathons, qualified for Smart India Hackathon 2023, and shipped production AI systems at early-stage startups. Right now I'm at Bez, working on AI agent workflows, vector search, RAG 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. 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. 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. Twitter
  • 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. GitHub
