As team lead in a team of four developers I was responsible for full SDLCon the Credit Assessment Tool which included:

• Iterative process analysis, technical specification writing, 3 tier C# windows application architecture, design, implementation of SQL data model, overseeing and technical implementation of the software modules,unit-, regression- and user acceptance testing.
• The application architecture implemented the observer patternfor custom controls to notify a change in state. The application view requests data via background worker threads to ensure usability of the application.
• Manage project plan activities on a daily basis together with code reviews, refactoring of code and management of change requests.
• I collaborated with the business to ensure all their requirements were met, and the system architect to ensure system scalability, performance and reliability.Also collaborated with the offshore vendorto ensure the tool integrate with their Dealer Front End (DFE) system. The tool implemented the BMWFS USA framework 2.0 which uses web services as a middle tier to communicate to the database of the DFE system and the existing Retail system, with a significant improvement in turnaround time (75% of decisions within 15 minutes) and quality of business.
• Due to the significant improvement in the business process and the quality of the Credit Assessment Tool I was promoted to Technical Lead.
• Designed and implemented a multithreaded WPF UI (DispatcherObject,MVVM) for the day end bulk process, together with C#.Net dynamic linked libraries (COM object) to read/write data between the existing BMW retail system (VB6) and CollectSmart (third party) that manages clients with accounts in arrears.
• This implementation significantly lowered the delinquency rate for business operations.
• Wrote a multithreaded WPFbulk document printing generation tool.
• The daily business process was improved by automatically printing on average 200 different letters to be mailed where previously each letter had to be printed manually.
• Wrote a tracer allocation component in VB6 for the existing BMW Retail System as part of the requirements together with updating existing components.
• Developed a C# desktop application for users to log their daily time against project, division and task.
• Developed a C# web service interfacing with SAP system for BMW employees (Fleet management) to apply for credit without displaying sensitive information.
• Developed a C# windows service to generate word documents for a credit application making use of WCF(SOA). A web servicehosted within the service received a message via http from the client with the reference number of the client applying for credit.
• The New Lending Suite (NLS) project I was responsible as Technical Lead for:
• The initial interface designs (XML, XSD) to be implemented between internal modules and NLS. The initial design consisted of creating use case documents for all the required business processes, i.e. deal activation, reversals, payout to dealers, etc. I worked together with the project manager and other relevant business users to define all the required use case scenario documents.
