German Engineered Ruby on Rails Solutions & Reliab...

Germany - Last active: 1 month ago - Tests: 7 - Portfolio: 3

Hi, I'm Niels, a seasoned software engineer based in Germany mostly working on web applications of all kinds using Ruby on Rails (3 and 4), (My)SQL, mongodb, redis, HTML(5), CSS and JavaScript in an agile manner. I also set up and maintain Linux servers. Several applications that I architected, implemented and maintain are in active production use. Please see my portfolio for details. I have years of experience as a senior developer – working solo, in co-located teams as well as in distributed teams – and hold a postgraduate diploma in Management of Software Projects. My greatest prides are proactiveness, reliability and good communication Please note that I do *not* do graphic design. Not for a lack of interest, but for an unfortunate lack of artistic talent. Sorry! :)
