Sundar Gautam Senior React Developer & Team Lead

I design and build fast, accessible products with React.js, Next.js and TypeScript. In 6+ years I've shipped an AI HR platform, an international art marketplace, apartment-management apps, Tream (games for TikTok LIVE) and a live-score site with 400+ daily readers. Today I lead the team at AITC International.

(01)  About

A developer who sweats the details

About me

I turn messy product ideas into fast, reliable React apps, and help teams ship them with confidence.

Today I lead a development team at AITC International in Bhaktapur, where I architect React and Next.js front ends and design Node.js APIs. I have also worked alongside our Flutter developer on the AITC Homes mobile app to grow my cross-platform skills. I care about clean, modular code, performance (code splitting, lazy loading, memoization), and interfaces that feel fast on every device.
