Software Developer & System Architect

I am a software architect & developer with over 18 years of experience. I specialize in designing, developing and connecting various systems and technologies together, starting from embedded systems, through web, mobile and desktop applications, ending on backend (server-side) software. I'm also system administrator and a Linux-geek. Feel free to contact me if you have any work to do! Especially C++/C/Python/C#/Linux related. You can find much more information on my website. I also encourage you to check my GitHub profile.
