FitFlash

Last autumn I got involved in a project that turned out to be a lot more interesting than I expected. FitFlash is a marketplace app for fitness and wellness services. The idea being that local gyms, yoga studios, and sports clubs etc. can post their upcoming sessions, and people can find and register for them all in one place.

I came on board to handle the technical side of things. We had an early prototype built with Apple's native tooling, which worked fine for getting the concept off the ground, but it quickly became clear that limiting the app to iOS would cut off a big part of the potential user base. So we made the call to rebuild with a cross-platform framework instead: one codebase, both iOS and Android.

That decision shaped a lot of what followed. Building for two platforms at once means you have to be more deliberate about how you structure things. You can't lean on platform-specific shortcuts. Everything from navigation to real-time data sync to push notifications had to work consistently across both.

The backend side has been equally involved. The app needs to handle things like real-time availability updates, registration state management, location-based discovery, and transactional notifications, both push and email, all tied together in a way that stays reliable as the user base grows. I've been responsible for architecting and building all of that.

It's been a genuine full-stack project. Authentication flows, cloud infrastructure, maps integration, third-party messaging services: the kind of work where you end up touching a lot of different systems and have to make them talk to each other sensibly. We're currently in the testing phase and really close to launch on both app stores. Still a lot to do, but the core product is solid and it's been a good project to be part of. We have development ideas and plans that will keep us busy for years to come.
