    Android developer with experience in networking

    Croatia - Last active: 1 month ago - Tests: 7 - Portfolio: 1

    During my education and work years, I strived to get experience with all the technologies available to me, and with my analytical mindset I always preferred a troubleshooting oriented role. Started out as tech support at an ISP, and got promoted to a NOC agent, where I learned a lot about Layer2 networking, VoIP and other telecom services. Later on, I switched jobs and got to a position of an IT manager in a company with more than ten branch offices where I had the task of building a complete IT system including servers, networking, work stations and VoIP solutions. Currently I'm employed in a small company where I'm working as a project manager and a Java systems developer for various solutions based on Android devices, Mikrotik routers and Asterisk PBX systems. In free time I always fiddle with something, so I have experience in PHP, MySQL, JS and web design.
