Full-Stack Developer at Self-Employed building an auditable order platform and optimizing enterprise systems.

Message

At Self-Employed, I’m building an admin platform that replaces a manual WhatsApp- and call-based workflow with an auditable order system. I delivered Version 1 for client demo and live review, including order tracking and design revision history.

At Infisuite Technologies, I independently migrated a legacy PHP enterprise system to React and Node.js/Express. I delivered and maintained 10+ enterprise modules and built secure REST APIs for web and mobile platforms.

For the GMP project at Infisuite Technologies, I reduced page load time from about three minutes to 10–20 seconds and API response time from about two minutes to about 20 seconds. Server-side pagination and lazy loading helped address memory bottlenecks and UI freezes.

Earlier, I developed government-project CRUD modules at Pixel Studios and Django REST APIs for the Sanjeevani Back Office healthcare platform at Sonakshi Software Solutions. My work spans React.js, Node.js/Express, Python/Django, MySQL, and AWS.
