About me
Hands-on fullstack developer with 15+ years building web applications and digital platforms, with a strong background in frontend engineering and modern JavaScript/TypeScript development.
My current stack includes React, Next.js, TypeScript and component-based frontend development, backed by extensive experience integrating frontend applications with PHP/Laravel backends, REST APIs and relational databases.
I remain directly involved in implementation while also bringing experience in application architecture, frontend/backend boundaries, development standards, code review, Docker environments and automated delivery.
