Technical Expertise
Circuit Design
Circuit design and development for analogue and digital circuits, high speed PCIe buses and interfaces like USB, RS485 and ethernet.
Often also involved with prototypes is writing the firmware to operate on the micro-controller or micro-processor used. This has been normally written in embedded C.
Technical Support, Analysis of Issues and Problem Solving
Various issues can appear during development, and I have provided a consulting service to provide technical insight.

I have resolved technical issues, provided circuit analysis, root-cause analysis, fault analysis, design reviews and reports.
