The Customer's Pain

This was an Android development freelance project where I was challenged to work with a completely undocumented codebase and fix critical bugs without any handholding. Quby's smart thermostat app was crashing frequently, draining battery, and customer complaints were mounting. I had to figure out the architecture, identify issues, and implement fixes all on my own.

The Full Story

This project represents the kind of technical leadership and strategic thinking that drives successful platform transformations. Working with Quby (Toon by Eneco), we tackled complex challenges that required both deep technical expertise and business strategy alignment.

The approach combined hands-on technical execution with strategic oversight, ensuring that every technical decision supported broader business objectives. This is the kind of fractional CTO engagement that transforms companies from being limited by their technology to being empowered by it.

The results demonstrate what's possible when you combine migration expertise with technical leadership: faster delivery, improved team productivity, and sustainable growth built on modern technology foundations.
