Who I Am

I'm a Lead Software Engineer based in Noida, India, with deep expertise in backend architecture, AI integration, and engineering leadership. Currently at Monotype Solutions India, where I architect and scale backend platforms handling millions of daily requests.

My work spans building event-driven microservice architectures, shipping production AI features (semantic search, MCP servers, RAG pipelines), and mentoring engineers into senior roles. I'm passionate about writing clean, testable code and sharing knowledge through technical writing on Medium.

Beyond code, I contribute to open source, have authored 5+ technical RFCs, and am an AWS Certified Developer – Associate.
