AI features in production

Platforms: web, mobile, desktop

I build things that ship, scale, and stick — full stack with a real AI-product layer. Grounded in product reality, I think about delivery, not just implementation.

A progression from network QA at TCS to product-facing full stack at Enablix: RAG chatbot, LLM pipeline, mobile app, document tooling, audit systems, and most recently Clake — an Angular 19 micro-app platform with a native AI chat, citation engine, and artifact builder on top of a NestJS/PostgreSQL core.

Off the clock I ship macOS tools — QuickNib, an open-source Electron code notepad with a Homebrew tap.

Based in Hyderabad · Open to remote.

How I work

Three habits that
survive contact with production.

Ship the thin slice first

One real path working end to end — UI, API, data — before widening anything. Integration problems surface while they are still cheap to fix, and there is always something demoable.

Own it past the merge

Two years in QA left a habit: I write the test plan, watch the feature in production, and fix what I broke. Delivery is not a handoff to someone else's dashboard.

AI needs a product layer

A model call is not a feature. Citations, fallbacks, structured output, and a way for the user to tell when the answer is wrong — that is the part that takes the engineering.

Angular 19 standalone shell that loads specialised micro-apps side by side over content sets stored as PostgreSQL JSONB. Built the host container, instance lifecycle, and shared filter components (date range, multi-select, toasts), against a NestJS + TypeORM API with a JSONB query builder supporting contains, between, in, and date operators with pagination and sort.
