About

On this channel, I post videos about programming and software design to help you take your coding skills to the next level. I'm an entrepreneur and a university lecturer in computer science, with more than 20 years of experience in software development and design. If you're a software developer and you want to improve your development skills, and learn more about programming in general, make sure to subscribe for helpful videos.

I post a video here every Friday. If you have any suggestion for a topic you'd like me to cover, just leave a comment on any of my videos and I'll take it under consideration.

Thanks for watching!
