Slovenia - Last active: 12/26/2014 - Tests: 2

In the last decade, I've tackled projects (personally and professionally) of all kinds that have used ANSI C, C++, Objective-C, PHP, Ruby and Node.js. Lately, I've mostly been developing web applications with Node.js and PHP, however I've stayed sharp with my Objective-C skills (by developing iOS and Mac apps/jailbreak tweaks for fun). I've also acquired skills of range of dev-ops skills, which include Bash, SQL, NoSQL (Redis, Mongo), Hadoop, AWS, load-balancing. One specialty of mine is also being very familiar with SAP technologies (particularly with writing ABAP applications). And even if something is new to me, I'm not afraid to step out of my comfort zone as I'm eager and willing to learn and acquire new skills. As such, I will tackle any interesting project/opportunity that presents itself.
