I am a problem solver, not the guy who will tell you "it's compiling, please wait". I always want to know what is your problem and want to perceive it on a human & business level. I don't want to only know programming. Being a dev is extremely interesting, educating and exhausting experience because you get to learn lots of business areas -- big and small. I enjoy constructive criticism and welcome teams that aren't dominated by Hitler wanna-be leaders. Full-time & on-site jobs -- forget it. I work remotely with flexible hours, and always will. Stuff in the programming I enjoy the most: * Integration and interoperability: finding out how to connect very different systems (different OS, different language). * Refactoring: modify a system without adding or removing functionality to make it more manageable, or to improve performance, or to provide connectors to new technologies. * Asynchronicity: I enjoy the complexity -- from the simple multi-threading scenarios to the full multi-server cooperations. * Standartization: I am an enemy of the home-grown approach. Wherever I feel a well-known technology will be more suitable, I replace the home-grown solution with it. * Innovation: I am not afraid of proof-testing new technologies and evaluating them against the ones I am currently using. I never innovate just for the sake of it; technologies are being chosen on "will it be easier to maintain in the long run?" basis. Specialties: * Making backend software & providing most of the system administration needed for it. * Doing integration and interoperability of very different systems, utilizing XML and JSON APIs. * Processing big amounts of data. * Modernizing legacy code. * Making and/or maintaining websites. I learned quite a lot here but it's not one of my favourite things to do. I feel the frontend technlogies are employing too much change for the sake of the change. It's an endless chase which I feel won't bring anything productive soon.
