Hire this company. Opsero has consistently provided high quality, dependable designs, on time and on budget. Jeff Johnson is of character and integrity beyond reproach. One of the challenges that we faced as a company was finding an engineer who saw the potential in our design as we envisioned it; Jeff did, and the result is a product that surpasses what even the manufacturers thought was ‘impossible’. Thank you for a great design. Peter Monahan

We had Opsero design and build a complex controller board for us using the Zynq 70z20 dual ARM core with FPGA and multiple special analog features DAC’s, ADC’s programmable I/O supplies etc. Jeff had good knowledge and understood well what we were trying to accomplish. We used his experience with the chip to help us determine best paths for the design. His communication with my team was top notch and he stayed on top of the job during a long trip he had long planned, allowing us to keep on schedule. We would highly recommend him and will use him on future projects. Lance Jones

I have been very pleased with Jeff’s knowledge and accomplishments on the Virtex5 FPGA. He understands the ISE, XPS and SDK platforms as well as the ML506 eval board. His response to the project design and changes has been excellent. He has been very reasonable and fair with his time estimates. I have no hesitation in highly recommending him to anyone who needs FPGA help. Larry Jorstad
