I'm a Product Engineer at IDnow based in Berlin, originally from Romania and raised in sunny Spain. I build accessible, user-focused web applications with React, TypeScript, and modern frontend technologies. Beyond coding, I enjoy sharing knowledge through technical documentation, Communities of Practice (CoPs), and mentoring. I'm passionate about frontend architecture, web standards, accessibility (A11y), and writing clean, maintainable code.
