"Both Andre and Mike worked for me when I was manager of Texas Instruments' UK Design Group in Northampton. Their judgement was always sound, their circuits passed international compliance standards and they were both the key circuit architects (digital & analogue) responsible for TI's entire highly profitable, discrete network chip product range."

- Brian Shore; Texas Instruments UK Design Manager & later Engineering Project Director at Global Silicon.


In addition to his very strong technical skills, Mike has an open mind, a disciplined approach, and a willingness to take risks. Mike and I worked together to increase the usable data rate of an existing SerDes design by 25%. In two weeks we identified a technical approach and then shared the remaining effort equally between our two groups. The project was completed in four months, was successful, and was a model for inter-company collaboration. I am also aware that Mike's leadership has given TI's SerDes technology some important performance advantages, some of them subtle, over any other SerDes in the industry.

- Michael Steinberger; Circuits Manager Cray, & later Distinguished Member of Technical Staff at Signal Integrity Software, Inc.


I have known Andre for over thirty years as a system network chip designer at Texas Instruments. Andre is able to take high level system designs, and then determine how to optimize these designs between software and hardware. He can implement detailed logic in silicon. This unique capability to convert a system into a chip design, making both contributions to the system design and logic design, makes Andre a rare individual in todays world of specialization.

- Jim Carlo; President of J.Carlo Consulting LLC, IEEE Fellow, Ex chair IEEE802, Ex TI Fellow.


I have worked with Andre for many years, on multiple ASICs. He has always been the "go to" person for challenging problems, and consistently delivered solid solutions. He is an expert in his field, and I have sought his advice on numerous occasions. I highly recommend him.

I worked with Mike at Plessey and TI and he is a highly creative and commercially focussed senior engineer with s very strong track record of success.
