Shubham Jangid, frontend engineer. Six years on React and Electron products — a real-money poker client, a dealership platform, a digital signing system — mostly spent on the parts people only notice when they are slow.

Three habits that survived four companies.
Most of my work starts with a profile, not a rewrite. I measure first, keep the number, and change the smallest thing that moves it. The 1.4 seconds I took off page load at Tekion came from caching, lazy loading and render discipline — nothing was thrown away.
I lean on design patterns hard enough that shipping stops being risky. Reusable higher-order components, custom hooks, micro-frontends over module federation. The point is that the next engineer can ship a feature without reading the whole codebase first.
I review pull requests, run solution discussions, and mentor the engineers around me. Almost everything I know about frontend arrived because someone senior took the time to do this for me, so I try to keep the debt moving.
Numbers I kept, from work that shipped.
1.4s
cut from page load at Tekion, through data caching, lazy loading and cheaper renders.
54%
module test coverage on the digital signing platform, up from 18% in a year.
60%
fewer upgrade failures at Baazi Games after reworking how releases reach the desktop client.
34%

Two products I designed, built and run on my own. Both are live.
GST invoices that your accountant won't send back.
Tax invoices and quotes for small Indian businesses that raise a handful of invoices a month and need every one to be right. I designed, built and run it on my own.
Under the hood
Run the club, not the register.
Memberships, attendance, schedules and a website of their own, for gyms and studios still running on a paper ledger and a WhatsApp group. Every club gets its own themed site, on its own domain.
Under the hood
Running on it
A 24-hour gym in Delhi runs its public site, memberships and member logins on FitClub Connect.
