About

Jan Pěček

My name is Jan Pěček, and I am Building Software

I'm a software builder, software engineer, and I like my work. I'm mostly around mobile, web and back-end solutions. During my career, I've worked for such companies where I got a lot of skills. I prefer making nice, clean and readable code, testing it and make a proper documentation. I like to create new solutions, build an architecture for them. I also have experience with leading small teams, I appreciate learning new things any time. I had started working during university studies and I finished them with 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 living abroad and travelling a lot although my home city is still Prague.
