I’m looking to work on exciting projects and with people who care about technology and about providing cutting edge solutions to business problems. I’m interested in providing reliable tested software solutions to users who need them in short time frames consistently. If you’re interested in what I can bring to your team of developers and your software development cycles drop me a line.
I’m a predominantly Microsoft.NET C# developer with over sixteen years experience in architecting and developing software systems using industry recognized patterns and practises. I’m a believer of test driven development ( TDD) and the natural fit that it has with Agile and XP development methodologies. I’m interested in messaging based event driven architecture (EDA) and the loose coupling it achieves which in turn allows for highly scalable systems.
I’m also an avid supporter of domain driven design (DDD) as a way of bringing development closer to the business and effectively delivering business requirements whilst also delivering a system which mirrors in the code the way the business should run. Another paradigm I’m investigating and working with is command query responsibility segregation (CQRS) which fits nicely with the impedance mismatch between relational data structures and the object orientated world most developers live in.

As a consultant working for Digiterre I worked primarily as the team lead on a large project for an EON Energy Trading developing a Transfer Pricing management tool. The project team was spread over London, Dusseldorf and India and required strong coordination and communication to keep the project on track. In the last two years we have brought this project to completion and are now in the process of handing it over for support and maintenance to an outsourced provider chosen by the EON.
The solution we provided made use of Oracle, server side service components and a WPF user interface. The system worked on large sets of data output by models and involved a series of calculations and data manipulation in order to output the required reports and data analysis required by the business.

I worked as part of large team developing a budgeting application for the firms internal budgeting and cost monitoring of matters. The application was a web based tool relying on data from disparate systems from finance to firm control work management systems. Users of the system would budget costs of estimated work catering for different partners, fee-earners and other resources at different exchange rates. The budget was then eventually compared against actual outcomes of work done on a matter and various reports were available to help monitor the progress of a budget.
The budgeting tool was developed using agile / XP practices and methodolgies. Daily stand-up meetings, bi-weekly development iterations and breakdown of work into stories, tasks, defects and spikes. the application was developed in ASP.NET with ASP.NET Ajax 1.0 for a responsive, interactive UI.
The MVC/Model 2 architecture was used and test coverage of over 90% was achieved on the code base. The application interacted with multiple firm-wide components using WCF services and messaging using SOAP over TCP resulting in a loosely-coupled, service orientated enterprise architecture.
