    Right after finishing my 4 years B.Sc. degree in Computer Science, obtained at the Sapientia University, Targu Mures I started to work in the IT. After some years of work as a developer / software engineer I had the chance to change my role and try out something more dynamic and chaotic which means I started to work as a system administrator. This role allowed me to show what a single person can do with some basic knowledge and passion to clean up a complete development stack, make an order in servers and services so other people can concentrate only on development. After my first steps in administration, a new world was just opening for me which was the automatization of servers as much as possible. After 5 years experience as a system engineer I'm sure, we should automate as much as possible. It really helps to be far away from the chaos of wrongly configured servers and inconsistent service deployments, which in long term could cause really huge troubles. Specialties: • Automation evangelist • Proficient problem solving and technical skills • Practical design, development and architecture capabilities • Ability to learn new technologies fast  less

    Senior Ruby on Rails developer with 4+ years experience in the RoR technology and 10+ years in web development. My biggest strength is ability to design clean architecture for even very complicated products. I always design normalized databases and keep everything in conventions. I love to: - build apps with high performance requirements, including designing cache layer, configuring server environment etc. - create nontrivial solutions (ie. using metaprogramming) - create user friendly solutions My biggest achievements: - I've built middleware for very big mobile app which can handle thousands of requests per seconds on one dedicated server - I had own startup since my high school, which had 300 thousands unique users / 3 milions pageviews per month - I have participated in dozens of commercial projects (mostly RoR apps, few mobile - Titanium, iOS) and in most of them I was main architect and team leader  less
