Grzegorz Golda

Advanced programmer

Poland - Tests: 4

I am a passionate coder. Recently I've been developing primarily Unity3D/C# game prototypes for my own studio and some private web apps with Google App Engine, though I'm most experienced in solving algorithm and data structure focused problems with C++, which is language of my choice. I also worked on commercial Facebok ActionScript3 social game developed by established studio. Did several programming freelancing jobs with various requirements. My hobby projects in past 13 years were mainly oscillating around OpenGL/C++ renderers, C/x86 operating systems and many algorithmic contests like SPOJ, ACM online judge systems, TopCoder, etc. Programming language history includes: + (C64) BASIC and 6510 assembly + (Amiga 1200) SAS/C + (Windows and Linux) C++, C, Python, Erlang, C#, PHP, x86(_64) assembly + (modern web) JavaScript (jQuery) Other technologies used: + OpenGL 1.5 - 4.3 + Google App Engine with Python + Unity 3D with C# + Wordpress 4.0 My educational background is theoretical mathematics and computer science, although I never completed a degree for private reasons. Nevertheless I understand and enjoy high mathematics and theoretical computer science concepts, like computational complexity, proving algorithm and data structures invariants and properties and so on. I have never been employed on regular basis, because I've never wanted to. I am passionate about solving problems, especially software engineering ones, and have a very strong desire to learn anything that could be useful for me or other people.

Your database can be strictly for in-house use, or accessible via the Internet. I have accumulated a broad experience in both hardware and software in over 3 decades within the computer industry.
