📖 Summary

Java Server Analyst / Senior Developer / Technical Architect 15 years Industry Experience - Strong Skills Specialties: Java, Spring, Hibernate, neo4jSenior Java Developer @ Linkdex is a ground breaking SEO service. From May 2012 to Present (3 years 8 months) London, United KingdomHead of Development (Dorking Office) @ This role involves a fair degree of hands-on coding, but also responsibility for management of the 9 strong development team, standards, methodologies, toolsets, quality control, code management, infrastrusture, etc, with a free hand in terms of recommending and implementing change; close collaboration with Project Managers, helping them deliver their projects; line management of all developers and promoting expanding skillsets; involvement in technical elements of new business opportunities, tender responses, RFIs and RFPs; client interaction in both new business project situations; overall bringing rigour, best practice and personal development opportunities to the development team. From August 2011 to May 2012 (10 months) Senior Server Developer / Architect @ Originally hired to rewrite www.gospoken.com's PHP website, I created from scratch a Java / Spring / Hibernate server platform capable of sustaining multiple white-label brandings and multiple configurable billing engines, which now powers online bookshops for Orange (including the Prize For Fiction website), T-Mobile, WHSmith, Movistar in Spain (Telefonica) and SingTel in Singapore. The platform is fully internationalised, supporting multiple European languages, and many currencies. It is also capable of providing content to almost any web device, from primitive Nokia feature-phones through to modern smartphones and tablets, as well as e-reader (Kindle-like) devices, and a wide array of desktop browsers. The books sold are capable of being read on all these devices, through a variety of client-side technologies, including J2ME, Android and Apple apps, and using Adobe encrypted epubs for desktops and e-readers. At first playing the role of a “hero-coder”, the team soon expanded to 3, and then to 5 developers, plus UI developers. Starting as a simple Spring MVC / JSP light-weight webapp, I architected and coded the entire thing for the first few months, before shifting gears in order to grow the product to a corporate scale. Eventually the build was highly componentised and managed through Maven, with the next step being to transform large chunks of “internal” services into remote webservice apps, through the use of Spring Integration. Additionally, an entire separate webapp was spawned in order to administrate the bookshops and allow reporting of analytics. Internal search engine brings back results from over 50,000 books. From November 2009 to July 2011 (1 year 9 months) London, United KingdomJava Server Application Developer @ Tradespace is a huge B2B and B2C e-commerce website allowing thousands of small (and not so small) businesses to gain an established web presence. The architecture has 3 tiers: a web tier and a service/database tier, both implemented using a Spring based, lightweight framework deployed on Tomcat; plus an Enterprise Service Bus deployed with Fuse ESB (based on Apache ServiceMix). Each tier communicates using SOAP services; web layer implemented with Spring MVC and JSP 2.1; database abstraction with Hibernate. Largest and best run agile project I've been involved with. From July 2009 to October 2009 (4 months) London, United KingdomContractor @ Updates to multiple websites and creating new from templates; Struts and EJB3 on JBoss 4. From June 2009 to June 2009 (1 month) Senior Java Web Developer @ Ajax-intensive website for Incomes Data Services (IDS) for statistical data aggregation, filtering and charting. Statistical data on Pay Levels, Pay Settlements and Executive Compensation, are presented with feature rich, interactive filter controls which update data tables and charts dynamically through Ajax. Implemented with Java 6.0, Spring 2.5; the web layer with Servlet 2.5, JSP 2.1 and Spring MVC with Tiles 2.0, as well as jQuery. The charting was achieved with Flash based FusionCharts, interacting with javascript and XML updates from the server. The database layer used Annotations driven Hibernate. From January 2009 to May 2009 (5 months) London, United KingdomJava Web Developer @ As part of a small Agile team, rewrote and enhanced BSkyB's existing search engine, based on Google for web searches, and Autonomy for Sky site searches. Additionally, developed a Sky branded affiliate shopping site, with highly configurable editorials and including search functionality. Implemented with Java 6.0, Spring 2.5; the web layer with Servlet 2.5, JSP 2.1 and Spring MVC with Tiles 2.0, as well as Ajax technologies. Runtime management and performance monitoring achieved through JMX and AOP. Broad use of XML parsing technologies used throughout the applications. Extensive use of FitNesse acceptance tests to achieve a strongly agile, test-based approach. From March 2008 to December 2008 (10 months) London, United KingdomSenior Portal Developer @ Designed and implemented custom JSR 168 portlets and services for Skill Gaming's Funcurrent gaming web portal which is part of Skill Gaming's new suite of gaming and media services. The portal engine used was Liferay 4.3, and much of Liferay's own source code was extended or overridden to achieve desired effects, including ajax popups, portlet layout customization, skinning tricks, workarounds (such as for classloading), services customization and fixing Liferay bugs. The framework for portlets was JSF, with components being used and extended from Sun and Apache Tomahawk, as well custom components. Integration made good use of Spring and various framework bridges. From July 2007 to March 2008 (9 months) London, United KingdomWeb Application Developer @ Worked on upgrade to UBS's internal Equity Investor website aimed at constructing custom equity products for customers of their Wealth Management division. Equity Investor is a large application consisting of a web application built using Java 5.0, Spring 2.0 including MVC, Hibernate, and Ajax technologies with several Java 5.0 and C++ background calculation and processing applications. It also used GlazedLists caching. Databases used were Oracle and Sybase. The application also supported PDF generation through FOP/XSLT. Also worked on UBS's Presidium custom permissioning system, built using Echo2 web framework. From January 2007 to June 2007 (6 months) London, United KingdomWeb Application Developer @ Regul8 was built to assist financial services firms, with Financial Services Authority (FSA) and London Market regulation. Runtime configurable custom workflows are followed by advisors in their arranging of General Insurance, Mortgage, Retail Investment, etc. From these Regul8 produces FSA Returns and other compliance reports. The application extends to workflows for complaints and claims procedures; document generation and management; calculations and rules engines which raises alerts; electronic XML submission of Returns; and managing Principals* and Appointed Representatives*. The core is implemented with Java 5.0 and Spring 1.2 framework; persistence with Hibernate 3.1 Object-Relational Mapping (ORM); and the web layer with Servlet 2.4, JSP 2.0 and Struts 1.2.7. The rules and calculations engine is implemented with a custom framework built on top of Beanshell 2.0. The calculations are configured at runtime from database stored java code. Custom interfaces and extensions built on Struts’ Validator provided “dynamic validation” for each workflow element, and provided injection of the data into the calculation engine. Together with dynamic configuration of Struts’ Tiles mechanism, this allowed total control at runtime of a workflow’s configuration, whilst retaining slick & professional presentation and handling of a workflow’s data. Application security is a high priority: achieved through the use of sslext plugin for Struts, Acegi Security, the overriding of Servlet 2.4’s role-based security and data-based permissions framework. Document generation is done with XML which, through XSL, FOP and Open Office, creates the needed formats of PDF, MS Excel and MS Word. Expert CSS and Javascript give final polish to the usability and ease of use of the application.
