What I'm looking for

I'm looking to build product-focused web applications where I can own front-end features end-to-end, solve real user-flow problems, and create fast, reusable interfaces that evolve with the product.

At Drum’n’code, I build product-focused web applications across furnishing, construction, payments, and booking. I created a Chrome extension that cut product-add time by 63.4%, built search dashboards with maps and virtualized lists, and delivered merchant and operator payment portals with granular access controls.

I own front-end features end-to-end, from architecture and reusable UI patterns to API integration, validation, error handling, and performance monitoring. My core stack is React, Next.js, TypeScript, Tailwind CSS, and modern tooling, and I focus on interfaces that are fast, understandable, and ready to evolve.
