Hi, I'm Tim COREY

I learned software development the hard way, with lots of dead-ends, confusion, and knowledge gaps. I kept thinking, “It shouldn't be this hard!” Now I teach students how to think and code like professional developers. My goal is to make it easier for you to become a developer.

“With your knowledge and teaching style I just got my first job offer as a C# developer”
Corey
“Definitely worth the money you pay.”
Zafar
“I really appreciate the explanation of “Why”
Jamie
“Thank you so much”
Daniel
“I'd feel better having a colleague that learned from Tim's courses than a bootcamp”
KUMBALA80
“After completing the mastercourse I got two very nice competing engineering offers”
Ron
“Best I've come across”
Chris
“I have finally landed my first job as a software developer”
