10/2014 ? today: Hardware and software design

Role: Owner

Customer: [Company name on request]

Tasks:
I am the founder, owner and sole employee of [Company name on request] in Hong Kong, providing engineering consultancy and expertise. The current contracts are:

• Hardware and software design of a new control unit for an injection moulding machine. The design is an embedded controller with an Android tablet front end.

2009 - 2014: development 

Role: Development Engineer

Customer: BMW AG

Tasks:
Following the end of BMW involvement with Formula 1 racing, I moved to work on the development of concept prototypes of automotive electric drive components at BMW AG.

• Adapted standard BMW motor controllers for prototype vehicles using permanent magnet and externally excited synchronous motors, as well as one proof-of-concept project using an asynchronous motor.
• Wrote interface code to allow model-based software developed with Matlab/Simulink to work smoothly with the underlying system architecture. This interface software worked in a multi-processor environment, based on concepts taken from the AUTOSAT RTE, shielding the Simulink developers from the complexity of the underlying software.
• Adapted the BMW standard embedded OS (OSEK-based) for the TriCore TC1782 embedded processor.
• Software integration, build and release manager for various projects in the concept stage of development.

2001 ? 2009: Developed embedded logger and telemetry system

Role: Development Engineer

Customer: BMW Motorsport (Formula 1)

Tasks:

• Developed embedded logger and telemetry system in C for a multiprocessor Engine Control Unit (ECU). This included the logger data sampler, and flash-filesystem storage, data transmission over telemetry and Ethernet offload of the logged data.
• Developed the PC logger and telemetry decoder in C++/MFC for the ECU.
• Specified the feature set and internal architecture for the PC tool used by the engine and chassis engineers to configure the ECU. This tool is a C++/MFC application, and supports a large object-oriented COM interface.
• As technical project leader for the above, coordinated the work of a team of six software developers and testers, interfacing with the primary users, as well as managing the release process.
• System architect and project leader for the development of the BMW-specific tools for the Formula 1 race team using C#/.NET.
• Specified and implemented UDP-based communications protocol used between the PC tools and the embedded system, supporting multiple devices, each with multiple processors. A modified version of this protocol is used between the PC tools.
