_ Methodology: _ Siemens Evolution Process (bespoke software process for coordinated delivery and iteration with software, firmware, hardware, and on-site deployment technicians)

_ Description: _ SiPass has been installed at 1300 sites in 55 countries world-wide, securing notable locations Huawei HQ (2000 doors), Beijing Television Centre (784 doors) and Wohnpark Alt Erlaa in Austria (744 doors).

_ Achievements: _

• Smart Card Hardware API Development: Gained development expertise in smart card hardware APIs (GemPlus 332, HID 6055B).
• Innovative Feature Development: Developed a component supporting smart card access control for personal office rooms’ cylinders, a major product selling point. Contributed to 15% uptick in sales.
• DVR API Module Lead: Managed the Digital Video Recording (DVR) API module, responsible for image capturing sequencing based on alarm events. Developed C++ COM solutions for third party recording hardware innovations working directly with third party DVR vendors to source requirements. (C++, ATL, STL, COM)
• Live Anomaly Solutions: Delivered solutions to non-deterministic critical live anomalies, reducing end-user client complaints. Glowing feedback from client appraising analysis skills and won team award for ‘anomaly hunter’
• Recognized for my diligence in tracking and resolving bad patterns throughout the codebase. C++, C# .NET, COM, .NET Remoting, SQL Server, Wise, Memory Leaks
• Driven by a strong sense of ownership and a proven ability to deliver zero-risk solutions, I earned the trust of the project manager, who consequently delegated more critical site issues, enhancements, and development areas to me. Recognized for my leadership qualities and development expertise, I was assigned as the lead developer, managing a team of one to three engineers and taking full responsibility for the outcome of our key tasks.
• Resolved a complex, non-deterministic OLE Server Busy issue that had remained unsolved for many years. Through rigorous root cause analysis, I identified the issue as a performance related in the C++ RPC connectivity to the server. With the help of engineers experienced in these legacy modules (C++, MFC), we successfully resolved and delivered the solution.
• I was also assigned the responsibility for quality assurance of requirements, design, and API manuals from other engineers, in recognition of my attention to quality.
• Cost-Reduction Automation Tool: Developed a tool that cut language localization costs by over 40% reducing expenses by €1.5 million. With the growing number of languages (12+) per release moving away from manual steps, I was self-motivated to engineer process optimization. Promoted to localization expert and led a team of two to three engineers to push this engineering effort. (C# .NET, Scripting, C++ RC-WinTrans API)

_ Projects _:

SiPass Enterprise

• Designed and implemented the alarm module for system-wide alarm triggering, acknowledging, and reporting. Implemented integration bridge with SiPass (C++) and Enterprise (C#) for cross-communication interop. (C# .NET, WinForms .NET, Composite UI Application Block, NUnit .NET, COM+ Message Queue, XML)
• Created a custom hashing algorithm for license generation (C++.NET, NUnit .NET, C++ COM Unit Test, ASP.NET Unit Test).

Sipass Hardware Mechanics

• Designed & Implemented a module that supports pre-released smart card readers (two developments; GemPlus, HID, OmniKey) using a C++ API interface. (C++, OO Design, API interfacing). Managed the smart card division of SiPass from thereon.
• Designed & implemented a module that introduced turnstile door types to the system. Required conceptualisation of the turnstile operation. (C++, MFC, COM, SQL Server, XML)
• Led the Digital Video Recording division, developing C++ COM interfaces for third party device drivers. Developed enhancement C++ COM to maintain the video stream between the hardware in SiPass. (C++, ATL, STL, COM)
• Innovated a smart-card digital locking cylinder with a fellow engineer, providing a wireless unlocking effect for door users (HID’s new R&D invention). This was a success and the pattern we invented were used henceforth for future client-server developments. (C#, .NET, Design Patterns, .NET Remoting, SQL Server)

SiPass Integrated

• Designed & implemented enhancement where visitors are allowed access to the building on particular dates (C++, MFC)
• Designed & implemented enhancement where users can scroll through a large database of cardholders with high performance & concurrency considerations. (C++, MFC, SQL Server UDFs)
• Designed & implemented mechanism for system-wide fetching of database credential information. (C++, COM, C++ .NET, C# .NET, C++ Cryptology, Wise for Windows Installer). The challenge overcame was designing it with extensibility in mind as it was used for all future projects data access.
• Designed & implemented mechanism for system-wide fetching of system sensitive database credential information. (C++, COM, C++ .NET, C# .NET, C++ Cryptology, Wise for Windows Installer)
• Integrated an external legacy access control system into SiPass by designing a migration tool and developing integration features into SiPass. (C++, COM, MFC, ODBC)
• Resolved issue with where user sessions were not identified properly and caused reporting of logged in users incorrectly, C++, COM
• Designed 20+ system bite sized enhancements requested by product line (C# .NET, COM+ MFC, .NET Message Queue, Crystal Reports, C++)
• Designed & implemented VC++7 module to detect which SQLServer versions are available on the domain & implementing into Wise for Windows Installer. (VC++7, Wise for Windows Installer)
• Detected & resolved C++ quality of code criteria to pass official Windows Vista Certification
• Implemented Wise for Windows Installer packaging for packaging new system components.
