Plaor was a real departure for me. With the move back to Boston and away from consulting I wanted to try something new: game development. Plaor gave me the opportunity to apply my Java and Web experience in an entirely new way and on a very limited budget. My main responsibility was game stability and performance.When I arrived the team had little to no working knowledge of Hibernate or Spring, which had resulted in them requiring a quadrulpal extra large RDS instance to support 2500 concurrent players, as caching and transaction problems had been solved by turning off the cache and wrapping individual database actions in their own transaction. Consulting has taught me that all code bases have a story, and in order to develop trust within a new team it is important to make those stories your own so that the transistion to the new feels organic and owned by the group. For that reason, I used the strangler pattern to remove small slices of the code base, and demonstrate how the technology could be used to dramatically improve performance and reduce costs. This pattern is now being rolled out across the codebase, by all members of the team and I expect to be able to have quartered database costs.Plaor's small team meant that I got to stretch my devops skills, working closely with ops to build out clusters and create a more stable and repeatable build process.

ThoughtWorks is a global, agile consultancy currently ranked 12th most desirable workplace for software engineers by LinkedIn and regarded to have the toughest interview process in Technology by Glassdoor. ThoughtWorks differentiates itself via its unique approach to Agile and the high quality of its developers.

This variety has enabled me to utilize and implement agile techniques in teams from 6 to 40 developers with both co-located and multi-timezone teams.ThoughtWorks Lead Developers are still developers, but in addition to creating high quality software we are also expected to provide solutions, allow our team members to grow and experiment whilst providing the interface between the business and the development team.

Reimplemented a SAP analytics application to improve reliability and reduce maintenance using Spring and Struts backed off Endeca MDEX 6.Maintenance costs were reduced by introducing dependency injection which allowed much better unit testing. Better unit testing lead to a cleaner, more configurable design.

There was a period of six months between entering the US and receiving my Green Card. During this period I telecommuted back to the UK and did some small consulting contracts.

Helped with the redesign of guardian.co.uk as it was transfered from Tcl/Tk to Java.

The HMRC account was the largest IT account in Europe. My role as a J2EE developer involved designing, developing, testing and deploying a varied selection of high volume, security and profile web applications based predominantly on BEA Weblogic (6.1 - 9.1) on both Windows NT and UNIX. The majority of the solutions were batch processing, and migration from batch processing to message bus.

Recruited to full time role from the position of freelance researcher. Juice Meisters were primarily a business consultancy firm specialising in delivering global business growth through use of enhanced creativity.
