Senior Software Engineer

Mike Gebert

Robust web applications with PHP, Symfony and DevOps — with modern workflows that lighten teams' workload

About me

For nearly a decade I have been building web applications focused on PHP and Symfony. My background is a bit unusual: before software I trained and worked as a chef — the discipline and craftsmanship from the kitchen still shape the way I build software. Across my career I have led migrations, piloted teams and shipped greenfield APIs.

Outside of work I sail, play chess, boulder and tinker on a small Unity game. The same curiosity runs through all of it — whether new routes on the rock or new patterns in code.
