I have written dozens of professional apps, some are earning me revenue in Google play store, while some I did for various institutions here in Nairobi, Kenya. After studying Software Engineering at the university, I have been involved with various startups here in Kenya. During my free time I like sharing my knowledge on platforms like this, to help other students learn faster.
I teach by creating a project from start to finish, while coding in realtime and seeing the results in the emulator. This way students are able to learn the big picture and get going much faster.
