This is a cool project. But don't let the fact that you are building an app distract from the main goal (building a community).

I would suggest you first go to as many universities as you can, get their computer science students on-board, and then connect to their alumni network.

And start organising meetups, hackathons and other events. You need to start a small fire and it will kindle.

A simple website is good enough and you can start today. http://www.hackcampus.io/ is doing something similar in the UK.

A directory might not be so useful at this point.

I would also love to see the Tech space in Africa mature. I expect great things to come out of that continent, and building a community Is definitely a great place to start.

Put the code up on Github and I'll contribute.
