About me

Welcome, my name is David Šimák. I am software developer from Zlin, Czech Republic. I studied at SPŠ Zlín, Technical Lyceum. Now I study UPOL, Applied Informatics.
I develop applications mainly in Java, mainly for Android OS, but also newly in JSF (JavaServer Faces), where I combine html, css and javascript. I also have experience with Java FX for desktop applications and with C # for Windwos applications. 
I work on my applications but I also work as a programmer in Elisoft s.r.o. where I develop EKONOM receipt and other projects.
