I’m a senior PHP developer with 12+ years of experience building and maintaining web applications — primarily focused on backend systems, but equally comfortable delivering complete products end-to-end when needed. In my day-to-day work as a backend engineer at a German tech company, I design and maintain systems where structure, performance, and long-term maintainability matter. On Upwork, I bring the same approach — whether it’s fixing a specific issue or building something from scratch. What I typically work on: - Laravel & Symfony applications: backend systems, SaaS platforms, admin panels — from initial architecture to production - Full-stack web applications: I can take a project from idea to a working product: backend, database, and a clean, functional frontend - REST APIs & integrations: designing and implementing APIs that are reliable, well-structured, and easy to work with - Legacy PHP projects: refactoring and upgrading older codebases (PHP 5 → 8+), improving structure and maintainability - WordPress & CraftCMS: custom development, integrations, and performance improvements when a CMS is the right fit A few relevant examples: - Built and deployed a live streaming platform with real-time playback and custom backend logic - Improved performance of existing Laravel applications by identifying and resolving database and API bottlenecks - Delivered complete web applications independently, from database design to final deployment How I work: - I tend to be straightforward: understand the problem, suggest a reasonable approach, and implement it cleanly. - I don’t overcomplicate things, but I also don’t cut corners — especially on parts of the system that are hard to fix later. Background: - 12+ years of professional experience - Full-time backend engineer at a German company - Top Rated on Upwork with a 100% Job Success Score - Based in Germany (CET timezone), with good overlap for EU and US clients - Clear and consistent communication throughout projects If you already know what you need, feel free to reach out. If not, I’m happy to take a look and help you define the next steps.
