Engineering interfaces since 2020
I makethe webfeel instant.
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.

Two companies.One obsession.
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.
Saleshandy
Joined senior. Became frontend lead in seven months. Grew three engineers to seven and shipped the product’s revenue surface.
Architected AI Sequences and rebuilt the multi-step sequence builder.
Shipped NestJS APIs plus Twilio access-token and webhook handling.
Moved Lighthouse performance from 25 to 53 and cut builds by 30%.
Architected around 20,000 server-rendered pages with dynamic sitemaps.
Valens Datalabs
Three and a half years across a high-traffic storefront and the CMS that kept its business moving.
Shipped the storefront’s first working proof of concept in one week.
Cut cold load time from 5–6 seconds to 2–3 seconds.
Built a configurable CMS for pages, orders, and virtualized lists.
Created customer-journey and transcript-analysis dashboards in D3.

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.
Designed an AI-first workflow where one developer takes a feature from analysis to release.
Helped new joiners ship independently in their first weeks by writing down the path.
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.
