Engineering Scalable Frontend Solutions
I am a Senior Frontend Developer based in Szeged, Hungary, with 8+ years of experience in architecting and building responsive, user-focused web applications.
Specialized in the Angular ecosystem (v18+, RxJS, NgRx, spartan-ng, Angular Material), I have a proven track record in delivering complex admin interfaces, legacy desktop-to-web migrations, and secure API integrations (OAuth2, Keycloak, Open Banking/PSD2).
I focus on writing clean, maintainable code, optimizing component performance, and creating intuitive user experiences while collaborating closely in cross-functional teams.
