    German Engineered Ruby on Rails Solutions & Reliable Project Managment

    Germany - Last active: 2 days 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! :)

    Leader of Wide Teams

    South Korea - Last active: 1 day ago - Tests: 4 - Portfolio: 9

    I'm passionate about software craftsmanship and adapting agile practices for distributed teams. I love working with smart people to solve hard problems. My goal for the last few years has been to build a team culture in the model of Hashrocket and PivotalLabs but entirely distributed. For the last 5 years I've been leading very wide (globally distributed) teams helping them to active as close to co-located efficiency as possible. Currently I think we can get about %90 of the efficiency that could be achieved with a co-located team and that missing %10 is more than made up for by the other advantages of having a wide team. I've also been working with ruby (and rails) for almost 10 years now i.e. since rails was 1.0. In my recent projects I was the lead developer on the teams that built pawlinks.com, plateology.com, subout.com and textgen.com.
