Don’t just take my word for it
I worked closely with Jean for several years while he was contracted to Ford Motor Company. His in-depth knowledge of protocol analysis and network troubleshooting are second to none. Jean helped to solve many complex application and network issues while he was working with us. He was a definite asset to our team. His skills are solid and I would highly, highly recommend him!

I worked closely with Jean over a number of years at OPNET and later at Riverbed. His knowledge of IP, use of protocol analysis tools and excellent troubleshooting methodology helped during several client problems. In addition to his technical expertise (which is extensive), Jean is an excellent documenter and helped edit several documents that I’d written for customers. I would highly recommend Jean as a Senior Network Engineer and Network Architect.
