We work on high-quality PHP and web-based projects.

We're software engineers at heart. We're passionate, competent and experienced. We help planning, designing, developing and maintaining excellent software.

As an open-source enthusiast, we enable others building awesome projects. We care about high-quality, reliable projects and enjoy pushing the limits. For one, I'm a maintainer of ReactPHP, a ground-breaking, low-level library for event-driven programming in PHP. I also maintain a large number of open-source projects my own. If you're into numbers: My own projects have some million downloads on Packagist, a few million downloads on Docker Hub and some thousand stars on GitHub.

As a freelancer, we help my clients building excellent software. To us, software engineering is not about producing code. It's about providing value by helping build the right thing.

If you want to learn more about my projects, you may also check out my profile on GitHub. Need help with any of my projects? Get support! I also offer professional consulting, custom development services and issuing invoices for sponsorships of releases and for contributions.
