About

Jan Pěček

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

I'm a software engineer and I like my work. I'm mostly creating mobile applications, I've been also a web developer. 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, travelling and piano playing. In the last time, I'm travelling a lot although my home city is still Prague.
