Software Engineer

Capital ID•  August 2006 - January 2012

As a programmer I was part of a small, but effective team of development experts responsible for the Capital ID Framework (CFW). The framework leverages .Net technology to provide Application Development Teams with lean building blocks. It contains data classes, a comprehensive workflow engine, an output generator, schedulable tasks and several user interface components. I began working on solving bugs and implementing new modules for ID manager. Gradually I moved on to more advanced duties like restructuring the framework. UI Layer: building new and richer controls, redesigning the way pages and control interact with the business layer. Data Layer: moving away from a static to an object oriented approach. I also implemented a system wide file wrapper for the secure handling of file based resources. Programmers at Capital ID need to be all-rounders. Besides programming new ID manager features I’ve worked with Application Development Teams on client implementations. This gave me the opportunity to work for clients as Unive, Ohra, Randstad, Rabobank, The Body Shop, Akzo Nobel and Starbucks. Techniques used: C#, Microsoft ASP.Net 2.0, Microsoft SQL Server 2005, HTML, CSS, JavaScript, XML, XSLT, Reflection, IIS
