Working with a small team of developers specialising in delivering APEX applications to support and enable business processes.

  • APEX 5 with Javascript, JQuery, AJAX, CSS, etc.
  • Extensive PL/SQL and database design to support the front end APEX application
  • Java and SAP integration
  • Private Financial Institution - City of London

    As lead developer for the full lifecycle of the Bank's flagship e-commerce project, I designed and developed the middleware Oracle database to interface with the Bank's legacy systems and a 3rd party front-end application. This large-scale, highly pressurised project ran for over 2 years and gave me exposure to a number of the advanced features and best practices of Oracle when building an OLTP/Operational Datastore such as:

  • Advanced PL/SQL (Use of BULK operations, analytic functions, Oracle Advanced Queues, XMLDB)
  • APEX with Javascript and AJAX
  • Materialized views
  • Oracle Messaging Gateway
  • Oracle Designer
  • Performance Tuning
  • 3rd Party Integration with IBM Websphere and Crystal Reports

  • Outside of this project I heavily utilised APEX and the Oracle Web Toolkit (mod_plsql) to create new and enhance existing internal applications that are key to the Bank's daily operations. The application suite was augmented with Microsoft technologies such as .Net (C#/VB/ADO), SQL Server, SSIS and VBA that I helped to develop.

    UK Border Agency (Security Cleared ) - London Suburbs

    Working amongst a large team of highly skilled developers, I enjoyed putting my Oracle skills into practice whilst constantly improving my Microsoft development knowledge. I was fortunate enough to work on both 2-tier and 3-tier architecture. This ranged from Visual Basic 6 applications that ran directly on top of Oracle databases to using ASP presentation layers, COM+ middle tiers and, again, Oracle database backends.

    Major UK Bank - City of London

    My introduction to the world of I.T came as a graduate trainee for this household named bank. Initially I found my way into development work through working with complex Excel macros and Visual Basic for Applications. This lead me to forge a role as an Oracle DBA/Developer role joining a team which shared the following responsibilities:

  • Oracle DBA tasks on 2 large databases, one an OLTP database with a Forms front end, and one a datawarehouse optimised for Business Objects reports
  • Provided bug fixes and enhancements to the batch processing which was developed in PL/SQL and ProC* and controlled via Cron jobs executing Shell scripts
  • Provide on-call support 24/7 x 365 for the databases and the overnight batch processing
