    FP Developer / Mentor

    United Kingdom - Last active: 24 days ago - Tests: 2

    I'm an expert in Clojure and Scala functional programming, and scalable systems. My greater background is in Java development and I have sufficient knowledge of Javascript and web front end programming to be productive. I'm well versed in all stages of application development, from the early planning and pre-planning days on to post release. I'm a big fan of agile and the devops movement, and I love to work in great cross-discipline teams. I've been remote contracting for over a year now, I'm a great communicator and familiar with a wide range of remote collaboration tools. Before this I was an employee at Mind Candy, an entertainment startup based in London, where I was working on Scala and Java development, at first on the Moshi Monsters game and then later leading back end development on the Moshling Rescue mobile and Facebook game. Both titles required efficient, well designed code able to scale to many concurrent users and easily handle times of peak load. Throughout my time at Mind Candy I also acted as a mentor to other members of staff that were coming newly to Scala from a Java background, helping to ease their transition and become fully adept at writing idiomatic functional Scala code. As well as development I've been involved heavily in "developer multiplier" tasks, through such things as adding continuous integration servers, building a deployment pipeline, adding code metrics and other, more manual, things such as code reviews. I'm a big fan of sharing information, presenting what I'm working on and interested in and hearing about the same from others. I can help you with development, system design, choosing a database (SQL and NoSQL) and designing data types, scaling systems, migrating from Java to Clojure or Scala, improving your tooling and build chain, and more. I'm available for long term engagement, or for shorter projects.

    Rails Dev With Diverse Skill Set

    United States - Last active: 7 days ago - Tests: 5 - Portfolio: 5

    Hey, what's up? Thank you for reviewing my profile, I'm glad you stopped by! My name is Dave and here's the skill set I can bring to your project or team: Ruby on Rails Development - Experience with Heroku, Postgres, Devise, Pundit, Paperclip, Geocoder, etc. Front End Development - Bootstrap, Sass, Less, and a little bit of AngularJS Graphic Development and Retouching - 11+ years of Photoshop experience with an extensive focus on photo retouching, complex compositing, and stylized post production. Other Cool Stuff - Audio engineering, video editing / post production, marketing, and I'm a damn fine party planner! But wait, there's more! I also speak fluent English, am on EST time, and according to the Dali Llama, on my death bed I'll achieve total consciousness, so I got that going for me. On a serious note, I am looking primarily for ongoing rails positions that will challenge me and expand my knowledge. I also know that being able to fill some gaps when needed can be a huge benefit. I am happy to jump in and be of help in a range of areas outside of web development if needed, such as marketing and content creation. Finally, and as I would expect from anyone in web development in this day and age, I am very familiar with Wordpress and able to assist with just about anything a project could require. I would love to chat with you more about your thing / project / hopes and dreams / and the like... So please hit me up with a message and let's do lunch. Thanks again and talk soon!

    Linux sysadmin, cloud deployments specialist

    Czech Republic - Last active: 1 day 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.
