October 2013July 2014 (10 months) Cardiff

At Monitise, I was Scrum Master to three teams assigned to delivering Monitise mPOS, a Mobile Point of Sale Application for iOS and Android.

My responsibilities as Scrum Master included: coaching team members on various aspects of agile software development such as Scrum, writing user stories, estimating, forecasting, pair programming, TDD and BDD; facilitating key Scrum meetings such as planning and retrospectives; resolving impediments; making development process improvements and resolving conflict.

Scrum Master / Software Engineer


Nonprofit; 201-500 employees; Education Management industry

May 2013October 2013 (6 months) Cheltenham, United Kingdom

At UCAS I helped to deliver the 2014 release of the UCAS Teacher Training application.

The application included components using Java EE, Spring and Hibernate with Oracle and Informix on OC4J and WebLogic. My project responsibilities included coaching the wider project team on agile methodologies, assisting in release & resource planning and software development.

During my time at UCAS I led an effort to move release builds from IDE-based tasks on developer machines to Maven-based jobs on a CI server. In addition, I pioneered a universal database update mechanism across all database upgrades to simplify development and deployment. Other achievements included increasing pair programming take up, and code review practices.

Scrum Master / Senior Software Engineer

Specific Media

Privately Held; 501-1000 employees; Internet industry

December 2012May 2013 (6 months) Cardiff, United Kingdom

At Specific Media, I was part of a Scrum team responsible for designing and developing an application for capturing user analytics from Smart Televisions.

My work included writing a client component in CoffeeScript to invoke a Node.js REST server, which stores request fragments in MongoDB. A proprietary extract, transform and load (ETL) application was used to enrich those fragments with geospatial data, before being stored in MySQL, for interrogation by a proprietary reporting application.

I was also involved in the development of a Java EE-based advertising brokerage service, which was used by C++ and CoffeeScript components on Smart Televisions for selecting image and video advertisements for display to end users.

I was instrumental in improving the Scrum implementation within the team and the wider company. I was chosen to serve as the team Scrum Master after only three weeks and have become the coordinator of the Scrum Improvement Community.

Team Lead


Public Company; 501-1000 employees; MONI; Financial Services industry

May 2011November 2012 (1 year 7 months) Nantgarw, United Kingdom

At Monitise, I was part of a professional services team delivering mobile banking features to Visa.

I successfully delivered a RESTful service for locating ATMs and Visa payment terminals across the USA using Spring, Glassfish and Oracle. I refactored the existing service to improve the way distances between locations were calculated, and wrote a comprehensive regression test suite in JBehave.

In addition, I was part of a team who delivered an m-commerce platform to a joint venture between Monitise, Carphone Warehouse and Visa in an extremely high-pressure environment. The application used Spring, Apache Camel, Glassfish and Oracle to take credit card payments, conduct fraud checks and integrate with numerous retail applications over SOAP. I was awarded for my outstanding contribution to the project after recommendations from my peers.

As team leader, I used my influence to introduce Scrum concepts, including a sustainable pace, a product backlog, backlog grooming, sprint reviews and retrospectives. After a 3 month trial period, the team abandoned Scrum to better adapt to the customer’s needs, but retained a lot of lessons and improvements.

I also contributed to the award-winning Natwest and RBS mobile banking applications on iOS, Android and Blackberry through improvements to Monitise’s mobile money platform.

At NetDev, I was responsible for introducing performance improvements on the flagship call-handling application, in addition to working on new features and fixing defects.

I increased the call-handing capability of the application from 160 to 400 calls-per-second on the same hardware by introducing a messaging-based replication mechanism using JMS.

The application used Restlet, Google Guice, MyBatis and TimesTen in a Java SE environment.

Software Engineer

ThruPoint Ltd

January 2008March 2010 (2 years 3 months) Cardiff, United Kingdom

At Avaya, I was part of a team specialising in security. As part of this, I was responsible for delivering the client and server components of a certificate and key distribution application making use of the Java Cryptography Architecture . I was also a key contributor to the project tasked with migrating Avaya’s VOIP application server from sockets to NIO for SSL traffic.

Whilst at Avaya, I began work on an open-source PKI enrollment library. Eventually my work was licensed back to ThruPoint for use in mobile device management on Android and Blackberry.


Technical Director

Wired Media

Privately Held; 11-50 employees; Internet industry

At Wired Media, I designed and implemented a content management and e-commerce platform used by small and medium enterprises. The platform was based on PHP and PostgreSQL, and deployed on Apache and Microsoft IIS.

I also delivered a prototype application for larger customers based on the emerging JSR 286 Portlet specification, using Apache Pluto, Apache Tomcat and PostgreSQL.

I was responsible for all aspects of the technical direction of the company, including recruitment, training, networking and server maintenance. Whilst at Wired Media, I introduced source control, managed backups, networking security and the migration to a managed hosting provider.

Firstly, the extraction of data from Oracle using JDBC for the generation of XML documents of user-specific property recommendations. The XML documents were transformed using XSL to create multipart MIME e-mail in plain text and HTML.
