About

Hello! I'm Pavel Tzekov, a software developer with 14+ years of experience in backend and frontend development. I have a bachelor's degree in Electrical Engineering from Amsterdam University of Applied Sciences.

What I like about software development is the constant change, continuously learning new things, and above all, to see happy and delighted users. Like Dave and Andy say in The Pragmatic Programmer: "We developers are incredibly privileged. We are truly building the future."
