    German Engineered Ruby on Rails Solutions & Reliable Project Managment

    Germany - Last active: 7 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! :)

    Senior PHP/Javascript/SQL Developer

    Australia - Last active: 1 day ago - Tests: 5 - Portfolio: 3

    Over the last 12 years I've worked with PHP, MySQL/PostgreSQL/MSSQL, JavaScript, HTML/CSS and related web technologies to create a large number of websites and web applications. I've worked for a number of startups and for a large listed company. My strength is the knowledge I have of what the web application stack is capable of, how interacts with the underlying server software/hardware and browser. This insight allows me to build robust, sophisticated and fast software. Most recently I have been building thick client side applications using Backbone.js and Require.js. I believe that the future of consumer software is going to be dominated by this type of software stack. It gives me great pleasure to be building the future right now. I also have excellent Ubuntu/Debian/CentOS Linux administration skills and have managed a large number of different servers. If you're after a serious and capable programmer then look no further.

    Linux sysadmin, cloud deployments specialist

    Czech Republic - Last active: 15 hours ago - Tests: 9 - Portfolio: 1

    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.
