I build the systems other engineers and designers ship with.

Tech Lead at Leena AI, Gurgaon. For 8 years I have built enterprise web products. Right now: a component library that designers, developers and AI assistants all build with.

Selected work

Three problems from Leena AI, and what I built to solve them.

Designers ship code

I built AI guardrails and skills so the design team can change the component library directly. Each change ships as a normal pull request.

  • Design systems

40designer PRs in production
One square per merged pull request.

The component library, inside every AI assistant

A custom MCP server gives coding assistants each component, its props and its usage patterns. Developers stop searching Storybook.

     reads props, variants, usage
     writes code with the real API

     No Storybook tab opened.

A build that got 90% faster

I profiled the legacy pipeline, removed the bottlenecks, and tested esbuild and Bun. Bundles got 50% smaller and Lighthouse scores went up.
