About
Full-stack developer in Rajkot, India.
I'm Swapnil Kotadiya, a full-stack developer based in Rajkot, Gujarat. Most of my work is business software: GST billing and inventory, employee and payroll platforms, licensing systems and vendor integrations, built on ASP.NET Core, React, TypeScript, Node/NestJS, MongoDB and SQL.
I also design and build marketing websites, with the same attention to performance and accessibility. I work end to end: architecture, backend, UI, deployment.
How I work
01
End to end
I take a project from architecture through backend, UI and deployment, as on Grevity, where I also built the licensing, the marketing site and the promo video.
02
Built for real conditions
Grevity bills with no internet and no server, from a USB pendrive. The timeshare platform keeps five vendor portals in sync and raises Slack and email alerts.
03
Measured, not assumed
The Infinitix site scored 100 in Lighthouse on desktop across performance, accessibility, best practices and SEO, with a real reduced-motion path.
