Full-Stack & AI Engineer · GoParkEasy

I build AI-powered products that work.

Currently at GoParkEasy — shipping RAG chatbots, real-time booking systems, and full-stack SaaS for real users. I don't just call LLM APIs; I build the systems around them.

Who I am

Backend systems, meet LLMs.

I'm a Full-Stack and AI Engineer based in Maharashtra, India — building AI-powered features and production systems at GoParkEasy, working across the stack from RAG pipelines to real-time infrastructure.

I've built a production RAG chatbot with Google Gemini and MongoDB vector search, architected a full-stack SaaS parking platform, and designed fault-tolerant async pipelines — always focused on making AI useful in real products, not just demos.

Outside work I'm obsessed with what's next in AI tooling — voice agents and agentic workflows — and I trade the Indian markets on the side, which keeps me sharp on risk and decisions under uncertainty.
