A bit about me

I build robust, user-focused products for startups, from full-stack foundations to agentic AI.
I'm a full-stack and AI engineer based in Mumbai, India, with 5+ years of experience building scalable products for high-growth startups, including Y Combinator companies. As the first engineer at Craze (YC S22), I've helped shape the product from the ground up: we began with an HRMS platform, then moved into agentic AI, and today I'm focused on AI video generation, architecting and shipping AI-driven products end to end. My focus now is firmly on AI: designing agentic systems, LLM and RAG pipelines, and generative-video tooling, all built on a solid full-stack foundation of React, Node.js, and Angular. I thrive in fast-paced startup environments and love turning ambitious, open-ended ideas into robust, user-focused products.
