Not everything fits in a plugin or standard package. I build custom work in PHP and Python: integrations between systems, internal tools and web applications that do exactly what your business needs.

Light, fast and maintainable

I like simple, readable code without needless dependencies. That makes software faster, safer and cheaper to maintain, also if someone else continues the work later. You get the full source code and documentation.

How we approach it

We start with a conversation about your process and what you want to achieve. I propose the simplest solution that works, with a fixed price or estimate. Bigger projects I build in steps, so you quickly have something working and we can adjust.
