Electrical Engineer (BSEE + MSEE) with 25+ years experience, located in Los Alamos, NM. IPC certified CID+ expert in PCB layout. I specialize in analog front ends, digital design, and mixed signal product development. I have done hundreds of PCB layouts, most of which are high layer count, mixed signal, high speed, controlled impedance, FPGA and microcontroller designs. Experienced in PCB production and manufacturing, with over 10 years experience operating a variety of pick and place machines. I don't just lay boards out - I build, test, program, troubleshoot, and document them. This allows me to know what works and what doesn't in a PCB design from a Design For Manufacturing (DFM) standpoint. Proficient embedded designer, implementing microcontrollers in C/assembly, or FPGAs in Verilog/VHDL, depending on requirements. I can write the code for your project from scratch, or optimize existing code that may already exist for a given project. Domestic, "Made in USA" production capabilities, able to quick turn small and moderate sized PCB production runs. Having someone in the US that you can directly communicate with regarding production may be beneficial to your project. I am extremely experienced in component selection and sourcing, from both domestic and offshore sources. If domestic manufacturing is not wanted, I can also coordinate to have your product manufactured offshore. Give me a partial design, an existing design that needs rework, or simply an idea for a product. I will work closely with you to get exactly what you want built, and get it to market in the minimum time possible. Inquiries and invites are always welcome, and I look forward to working with you!
