PROGRAMMING AND SOMETHING MORE...
Main page | Portfolio | Publications | PostgreSQL vs other DBMS | IT Humor | Music | Quotes | About me
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).
