FAQ
Common questions
Which technologies do you work with?
Backend: PHP with Laravel or Symfony. Frontend: Vue.js, Nuxt, and React with TypeScript. Plus Stripe for payments, Docker and GitHub Actions for deployment, and Playwright and PHPUnit/Pest for testing.
Do you work remotely?
Yes, remote-first. For workshops or kickoffs I am also available on site in the Stuttgart/Ludwigsburg region of Germany.
Do you take over existing projects?
Yes. I join existing codebases, modernize legacy applications, and take on maintenance or feature work — starting with a short code audit as a shared baseline.
What does working together look like?
A free intro call, then a concrete estimate with effort and timeline. Development is iterative with regular demos. Handover includes documentation and tests.
Are you available for long-term projects?
Yes. I support teams over months — embedded in your team or owning modules independently.
