    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! :)  less

    I would like to offer you my deep knowledge of servers hardware and software, which allows me to fine-tune servers according to their roles, and my ability to anticipate and solve problems in shortest time possible. No Windows please, Unices only, Linux preferrable. Lately my main point of interest has shifted to deploying and maintaining web projects in cloud environments. I am developing monitoring / management tool ( http://m-script.org ) and supporting existing installations, but I am very well familiar with all well known alternatives from both monitoring and cloud management side, so no problem to implement any of them. The point is, I know very well how it works. And how it doesn't, too :) I am interested in any system administration work, especially in cloud environments. The more challenging you setup is going to be, the better. Automated scalability, cross-clouds deployments, combination of traditional and dynamically scalable resources, DNS/Geo balancing - everything is possible, just let me know your needs.  less

    With many years of experience in various IT companies I am ready to propose following services on "as-needed" basis (sorry, no fulltime employment): 1) Complex engineering tasks related to server-side linux scripts, such as troubleshooting, code review, implementation/adjustment of complicated logic. Supported languages: python, perl, ruby, bash, lua. Haskell, erlang, clojure are possible as well. They are subject of special (lower) rates, due to lack of practical experience (versus solid theoretical understanding and general interest). 2) Advisory in organisational questions for small & medium teams. Workflows, infrastructure, staffing, project management (including risks management, resources management, planning etc). 3) High-level design of the service-oriented architectures, data processing (ETL) flows, devops solutions in linux/cloud environments. 4) Any kind of engineering/architectural work related to functional programming, evented programming, nosql. 5) Advisory/troubleshooting on nginx and hadoop, with basic practical experience in high-load web services and massive data processing. Rates are flexible, depending on particular case. Is this expertise exactly fitting your problem? If so, just message me. Not sure? Message me anyway so we will find an answer together.  less

    I'm a professional web-developer with 5 years experience in Ruby on Rails. You may find my pay rate higher than of other developers. Well, there're 4 good reasons for it: • When you hire me you pay only for productive work. I'm not billing my time spent on googling, reading manuals, etc. Only time spent on programming your particular task. • I'm not Mr. Know-it-all, but I know a lot. My experience includes coding on Ruby, C++, Java, Perl and PHP; HTML5, CSS3, jQuery and responsive design for mobile platforms. 8 years of MySQL and Postgres databases. NoSQL solutions like HandlerSocket and Redis. Searching engines Sphinx and Solr. • I'm a universal soldier, as good in server-side coding as in front-end development. Need to develop a completely new social network or clone some tips and tricks from existing web-site? Or just want to grab data from online shop and upload to yours? Set up Nginx web serve with Unicorn or PHP5-FPM? I can do all with no hassle. • Some developers don't like to manage with others' code. I love it. All my career I have been modifying someone else's code and feel quite comfortable with it. Keywords: Agile, Rails 3/4, Postgres, MySQL, NoSQL, Sphinx, Solr, HTML5/CSS3, jQuery, Bootstrap, Backbone.js, Nginx, Apache, Git, AWS, Heroku, data scraping.  less
