Past Work Experience

 GameStation project (http://www.gamestation.co.uk), a large-scale Web-based application in United Kingdom
A large-scale web-based application that has intuitive navigation for a fast and secure checkout. The Shopping cart persists across service invocations (WCF) without using session. Websites work with .NET WCF based White Label platform. This implementation was done using a high programming language (Visual Studio ASP.NET 2008, C# .NET 2008) and it has a feature for JavaScript ON/OFF. AGILE development methodologies were incorporated through the use of Scrum or Extreme Programming and Test Driven Development due to the nature of the product, client and developers character.

 Communicating Data from Wireless Sensor Networks in Real-time
An application that connects through the PC USB port to a serial COM RS-232 port in the Access Point of the wireless sensor network using C# (.NET Framework v2.0 GDI+ for 2D and Managed DirectX for 3D) and SNODE2 (PIC18XX inside each node in the network). Data from the wireless is received and displayed in real time in its 3D form. I've developed this application under the supervision and council at Ibaraki University, Japan. AGILE/SCRUM methodology was used;

 Fixed Asset System for a Bank (Financial Transactions Processing, Reserve, and Clearing House Activities)
Worked with key users to design and develop a complete package (Oracle 8i Database, Oracle Forms Developer 6i, Oracle Reports Developer 6i) for managing fixed assets in a bank. This system provides full control over fixed assets according to users roles, including: depreciation schedules (by month, quarter or year), asset detail, journal entries, projections, historical depreciation, asset additions, sales, abandonment, trades, transfers, asset dispositions including gain/loss (full and partial).
