My name is Khaled, I'm a programmer. In the past, I taught some junior students problem solving onsite, prepared some programming(contests) and published some online content/videos about programming ~5 years ago(since 2014) and I saw how that helped hundreds of people worldwide (result from old channel ex.1, ex.2 ). but i stopped sharing for some years.
Recently i decided to start sharing again and planned to do my best to present something more useful than any time before:)
i hope to see some support by subscribing to channel if you are interesting
