I work on the Core Platform at Leena AI, where the systems I build carry every conversation between an enterprise employee and an AI agent: the streaming runtime, the token auth, the channel integrations. When a message survives a pod restart or a dropped socket, that is my code doing its job quietly.

I build most of it with Claude at the center of my workflow. The review pipelines, test generators, and code search tools I wrote for myself now run for my whole team. Before this I was an SDET at Cognizant, which is why I still write code assuming someone will try to break it. Along the way I earned an M.Tech in AI and Data Science from IIT Patna.

Selected work

Agent Dashboard
