I'm Gabriel Tekombo, an Android engineer from Douala, Cameroon. For the last 8 years I've built mobile products for a carpooling unicorn, a UN agency, a private bank and a fitness platform used by millions. Same craft every time: architecture that lasts, UI that feels inevitable, and code the next engineer will thank you for.

Gabriel Tekombo, Senior Android Engineer

What I do

Platform engineering, app modernization, greenfield products. I replace legacy stacks with Compose and Clean Architecture, design modular codebases, and build the CI/CD and tooling that let teams ship faster.

How I work

Product-minded and metric-driven. I care about crash-free rates, build times and time-to-feature as much as elegant code. Remote-first since 2020, fluent in French and English.

Beyond the IDE

I write on Medium (Android Mood), maintain open source libraries, spoke at GDG Douala, and I'm a regular at Android Makers, droidcon and KotlinConf.
