About
A year and a half ago I switched from graphic design to mobile development, and the design background still shows: clients tell me my builds match the mockups down to the letter-spacing. So far I've shipped two production Flutter apps, a booking tool for a Kraków climbing gym and an internal inventory scanner for a furniture retailer. Small scope, quick turnaround, lots of communication.
