Wrote my first real app, a 3D robotics simulator in C using OpenGL and Win32 API many years ago.
Nowadays it's mostly TypeScript, Javascript, React, Java/J2EE, Spring.
Also versatile in Sysadmin/Cloud/Kubernetes and PL/SQL.
My formal education includes a B.Sc. in Electrical Engineering (2004.) and a M.Sc.in Telecommunications (2010.).
