Senior Software Developer
Primathon Technology Pvt Ltd • Fulltime
Sep 2025 - Oct 2025 • 1 mo
At Primathon, I worked on building scalable, production-ready web applications for enterprise clients. I designed a reusable widget architecture for a Shopify-style storefront builder, developed an automated widget registry for seamless discovery and integration, and built flexible custom widgets using Next.js and TypeScript. My work improved performance, scalability, and developer productivity while ensuring clean, maintainable code suitable for large-scale products.
