Engineering interfaces since 2020

Not a product.
A working record.

Six years deep in React and TypeScript. I find what makes products slow, rebuild what deserves it, and leave the team a faster way to work.

Saleshandy — Valens Datalabs

Speed is not polish at the end. It is architecture, product judgment, and a team that knows where the sharp edges are.

How I lead

The team shipswithout me.

I would rather build the system than be the bottleneck: analyses people use, grooming that ends in decisions, and work small enough to start Monday.

  1. Designed an AI-first workflow where one developer takes a feature from analysis to release.

  2. Helped new joiners ship independently in their first weeks by writing down the path.

  3. Scaled three to seven, then right-sized back to three as the roadmap changed. Both are the job.

Your move

Let’s makeit move.

Ahmedabad based. Open to senior and lead frontend roles, remote or relocating — and to full-stack, frontend-heavy roles too.
