Web Developer gumen.pl mail@gumen.pl gitlab.com/gumen github.com/gum3n


Since January 2015 I am a Web Developer in Stats Perform. I work in Scrum team coding mostly in JavaScript. We have built many portals that displays historic and real time sport data (statistics, video and visualizations). It's mostly front-end work but we also have built API's, WebSocket service and tools in Node.js.

Few Personal Projects

In spare time I work on simple projects. So I can rest from company complex codebases, try something new and have it finished in relative short time.

  1. http://awdesign.pl - Portfolio for friend.
  2. http://makramamag.com - WordPress theme for small company.
  3. http://metromax.pl - Very quick one page website.
  4. http://browarraciborz.pl - Website for beer company.
  5. https://github.com/devballteam/promonitor - GitHub Pull Request Monitoring.
  6. http://hard-wood.eu - Simple one page website for small company.
