I've built and maintained production commerce systems for MyPostcard/deinebriefmarke, documenting B2C API flows, strengthening authentication and anti-bot protections, and adding 185 PHPUnit tests across critical workflows. I also improved Laravel performance, deployment workflows, and long-term maintainability through technical documentation and tooling.
Across Progrentis, EPQ, and freelance projects, I've delivered responsive learning modules, modernized internal operations platforms, and built healthcare and advertising-management products from requirements through production. I work comfortably across Vue, React, TypeScript, Laravel, Node.js, and databases, collaborating with product and UI/UX teams while mentoring junior developers.
