Jan Pěček

My Name is Jan Pěček, and I am a Software Engineer

I'm a software engineer and I like my work. I's primary a web developer but at last time I'm creating mobile applications more. During my career I used to work for such companies where I got a lot of skills. I prefer making nice, clean and readable code, testing it (using unit-test) and make a documentation. I like to create projects from scratch, build an architecture and design it. I've started working during university studies but I've finished them and got the Master's Degree. There, I's learning a lot of about electrical engineering, microelectronics, algorithms and, of course, software engineering. When I'm not working I'm practising one of my favourite sports. I'm interested in taking photos and piano playing. Most of time I'm living in Prague, the most beautiful city in the World.
