About

I’m a Full Stack AI Engineer passionate about building autonomous agents that can think, collaborate, and take action. With 10+ years of experience in AI engineering and software development, I’ve worked with LangChain, AutoGen, and Crew AI, creating everything from research & data-gathering bots to trading systems, customer-support agents, and IVR voice assistants.

I design and deploy production-ready intelligent systems for startups and enterprises, architect multi-agent memory, planning, and tool integration, and I’m comfortable across the full stack with Python, TypeScript, and React. I’m seeking new opportunities and open to innovative AI projects or full-time teams to turn bold ideas into robust, scalable systems.
