At PromptLayer, I shipped features across Python/FastAPI and React/TypeScript, including a Tool Registry and an agent execution loop supporting 10+ LLM providers. I also built PromptLayer's official MCP server, exposing 60+ API tools to Claude, Cursor, and other MCP clients.

At Devsinc, I built an LLM-powered lead engagement pipeline that generated personalized outreach from behavioral and location data. Earlier, I developed Python and React applications and improved a Rails application's response times by 45% with Redis caching.
