Sascha Villing

Full-Stack Software Engineer

Hi, I'm Sascha Villing.

Konstanz, Germany · on-site & remote

I build reliable software end-to-end, from authentication, backend architecture, and API design to polished frontends.

10+ years from apprenticeship through mid-sized companies, enterprise, and the public sector, plus an M.Sc. in Computer Science. I get up to speed quickly in new domains and pragmatically build the solution that hits the real problem and stays maintainable for the long run. Reliable, easy to work with, and solution-oriented.

Backend
Spring Boot & Quarkus (Java), Laravel (PHP)
Frontend
Vue, React, Angular (TypeScript/JavaScript)
Auth & SSO
SAML, OAuth/OIDC, Keycloak, Shibboleth, federated identity
Apps
Flutter (iOS/Android), Tauri (desktop)
Also
system & API integration, automated testing (unit & E2E), accessibility (WCAG 2.1 AA), CI/CD, Docker

AI tools are part of how I work day to day, Claude Code most of all. I keep them on a short leash, though: I set the architecture, read every change before it lands, and own whatever ships. Good engineering gets faster with them. It doesn't make itself, though.

Full portfolio, CV, and references available on request.
