Hi, I’m Csaba Nemes.
Senior Frontend Developer Angular & UI/UX Architecture
Fast, secure, and highly scalable modern web applications built from complex business logic and legacy systems. I have 8 years of experience in building enterprise dashboards, clinical systems and data driven platforms.
Architecting the Frontend for Complex Domains
I am a Senior Frontend Developer with experience in Angular, TypeScript and modern web architecture. I'm based in Szeged, Hungary. For the past 8+ years, I've been working with companies in healthcare, fintech, and enterprise IT to solve tough data problems with easy to use interfaces.
I build data-heavy admin interfaces, integrate secure REST APIs (OAuth2, Keycloak) and bridge the gap between robust backend architecture and user-facing design. I love working in cross-functional environments where I can distill complex technical workflows into highly responsive, accessible experiences.
