Who I am
AI Architect. Blockchain Builder. Travel Enthusiast.
I'm Kunal — a Senior Staff Engineer who's spent 14 years turning "what if we could..." into production systems serving millions. Right now I'm deep in AI agents, RAG pipelines, and LLM orchestration in Toronto. I've shipped everything from a Walmart chatbot that 4x'd engagement to crypto accounting systems processing 200K transactions in 5 minutes.
Officially Canadian When I close my laptop, I'm either hunting for the perfect late-night icecreams (Indore still wins), debating whether Vinland Saga or Attack on Titan has the better character arc, or planning my next trip — 10 countries deep and Japan is next. Born in India's undisputed snacking capital, I believe the best ideas come from mixing things that shouldn't work together.
I'm the kind of person who'll help you debug a model at midnight and then send you a ramen recommendation. If that sounds like someone you'd want to work with — or just grab coffee with — let's talk.
