My specialty is in digital and analog circuit design, with emphasis on DSP and RF for communications systems:

WiFi, 3G/4G/5G, DSL, audio, digital, acoustics, bespoke systems...etc, as well as scientific and numerical analysis.

Implementations include ASIC/FPGA, firmware and full web stack development.

I design, code and model in Matlab, Python, Verilog, VHDL, bash, PHP, JS, SQL, Java, Swift, C/C++.

The depicted "P2000" in my profile picture was my first computing platform, a Z80 with 16K RAM and 42K "mass" storage mini-cassette. Those were the days of biking to school uphill and against the wind, both ways.

I am available for short and long term contracting work. You can get in touch with me by commenting on any of my older answers (good or bad...) and I will get back to you via LinkedIn.
