"A free man is one who is not subject to any other restrictions, except those imposed on himself. The laws of nature must be accepted. Their understanding is the essence of freedom."

"Wolny człowiek to taki, który nie podlega żadnym innym ograniczeniom, poza tymi, które sam na siebie nałożył. Prawa przyrody zaś należy zaakceptować. Ich zrozumienie jest istotą wolności."
Baruch Spinoza
I'm a full-stack PHP/C/C++/C#/SQL developer with some Java SE and Delphi background. x86 assembly doesn't scare me. Old school classic ASP and VBScript is not fun, but I have experience with it. Pascal is fine - from good old Borland Turbo Pascal 7.0 to Borland Delphi 2007. Creative back-end web development is my main professional activity. SQL - it rocks. Simple CRUD is just boring. I like to play with query optimizations and studying performance tuning tips for relational databases, but I'm not a DBA.

Connecting vary software components into one synergetic system is the way of my work. It's a mixture of PHP/C/C++/Java/C# code if necessary. Maybe something more - I'm open for new technologies and tools. Usually back-end should be associated with a front-end layer, so JavaScript, HTML/CSS/SVG and GIMP are my next weapons, but I prefer to be hidden behind server firewall. I'm not a web designer. I know HTML5/CSS3, RWD, mobile first paradigm, media queries, etc. so I can freely talk and collaborate with front-end developers, but not replace them (well, this site is not responsive - maybe I'll improve it in the future). If I have to do something at front-end side, I prefer coding in JavaScript only. Something about data layer. PostgreSQL is my favourite RDBMS. Currently I use MariaDB, PostgreSQL and damned MS SQL Server. Some time ago I intensively used Firebird also with its best pl/SQL syntax I've ever seen. If I need to cache, I use Redis or Memcached. Asynchronous and/or pipeline processing - Gearman with GearmanManager is my choice (PHP workers - image/video/audio conversion by ffmpeg, Imagick, data filtering, validation and persistency).
