Biography

Effi is 17. He is in his second year of software engineering at a university in Yaoundé, and he founded Droplet Labs on his own.

At 13 he was the one people in his neighbourhood came to: he installed operating systems, swapped memory and hard drives, and built small games. As the internet grew around him, so did the debates he kept following: the price of mobile data going up again, and every platform asking for a name and personal details just to sign in, with no one saying what happens to them.

He decided to build the answer himself: a way for people to talk to each other without handing over personal information, and, in time, without depending on servers abroad. Every project on this site was designed and built by him, from the user interface to the servers that run it, in Dart, Kotlin, Rust, Java and TypeScript.

Development philosophy

  1. 1Start from the hardest real condition: no network, an old phone, a small budget.
  2. 2Ship, then measure. A feature is done when it has been tested, not when it has been written.
  3. 3Write it down: each project keeps its decisions and their reasons next to the code.
