Marek Ventur

Full-Stack Developer

I have worked for different companies and industries, such as tech giant IBM, music industry disruptor and gambling startup Gamevy. At the moment I'm working at Amazon as a Software Development Engineer.

In my spare time I'm part of the team that designs and builds the increasingly complex conference badges for the Electromagnetic Field hacker camp.

I combine in-depth frontend and backend knowledge with the skills to plan and deliver successful projects.
