About me

Want to learn more about who I really am? Well, that's a complicated problem with no easy answer.

I have experienced a vast range of programming languages: while currently my main focus is on NodeJS and Javascript for websites, I have developed commercial software using PHP, Python and C# as well, and used C and C++ for non-commercial work. I am mostly working with MySQL databases, but also worked with REDIS, RIAK, MSSQL, SQLite and PostgreSQL DBs.

REST APIs are also not a new thing to me - I have worked with Facebook's API, creating applications for it, as well as some sport books APIs (like OXi). I have parsed XMLs and JSONs to provide websites with fresh data. As far as CMSs are considered, I'm mostly focused on Wordpress. For Javascript, I pick jQuery, but also worked with AngularJS. My first pick for version control system would be GIT.

I absolutely love to work on the projects that matter - big websites, visited by lots of people every day. Nothing makes me more happy than seeing a product I have helped build makes a commercial success.

Going more personal, I'm interested in many topics - from reading books (especially electronic ones; I currently use Kindle Paperwhite, but own eClicto, Kindle 3 WiFi, Kindle 4 and iPad 1 as well) through listening to music and watching movies/anime to taking photos.

I like playing RPG games with friends, squash and swimming. In my free time, I play League of Legends with my younger sister. Since I love to code, I take pride in helping non-commercial projects like Larpownia.pl.

I am a great fan of taking photos. Sometimes I try to get the "artistic" feel (and mostly fail badly), but most of the time I just want to capture unique moments in life.

If you're organizing an event (RPG/fantasy/sci-fi/literature/manga/anime convention, LARP, etc.) at my location (London, UK) and would like me to take photos during it, feel free to contact me through LinkedIn. Who knows, this might lead to a successful cooperation between us!
