Baruah.

I build cloud-native enterprise applications and AI systems end to end — RAG pipelines, vector search, and LLM integrations on Azure OpenAI and Anthropic Claude — with the cost governance, security, and resilience patterns production environments demand.

About

From RAG pipelines to published books — engineering with range.

I'm a full-stack engineer with 8+ years delivering production systems in .NET/C# and React/TypeScript, at companies including Crisis Prevention Institute and Microsoft. My focus now is enterprise AI: I've built RAG pipelines — token-aware chunking, pgvector similarity search, hybrid re-ranking — provider-agnostic service layers that swap between Azure OpenAI and Anthropic Claude at runtime, and tooling to track and govern AI spend. I care as much about the cost, security, and resilience patterns around AI as the models themselves.

My path is unusual by design: after building front ends for Showtime and Condé Nast, I spent 2011–2017 earning an MFA at Columbia and writing professionally, then returned to engineering through two internationally published textbooks on VR/AR development, teaching AP Computer Science, and architecture work at Microsoft. I'm trusted to drive architecture decisions and represent engineering with customers and stakeholders — because I can build the system and explain it.
