P30Skill was an online learning platform for Game Development, 3D Design, and, Mobile Application Development areas. We founded the P30Skill with two of my friends in high school.
We wanted to learn mobile application development but there was no course in the Farsi language so we decided to create one and make the other developers' life easier!
With the help of some paid experienced teachers. we produced many enriched video courses for Swift, Android (Java), Unity, Unreal Engine, and 3DS Max. Hopefully, we reached the 2.5 Average Position in some important keywords in the google search.
After 3 years and when we had become university students, we had no free time to keep the website and the courses up-to-date. So we had to shut the P30Skill down.
In the end, we were both happy and sad. Happy, because we have helped so many people to learn something new, and sad, because we couldn't do it anymore!

I started my professional career in Rahweb when I was 15 years old. I was working on some of Rahweb's customers' websites as a part-time web developer. I used to design website templates in Adobe Photoshop and then convert them to an HTML template using CSS and JS. When I had my HTML templates' codes, I started to make them dynamic by developing a custom CMS using PHP and MySQL.
