    Dan Midwood

    FP Developer / Mentor

    United Kingdom - Last active: 7 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.
