What I bring
End-to-end experience from specification, architecture and feasibility studies to transistor-level design, layout support, verification, EM modeling, measurements and customer-facing technical discussions.
Freelance Consulting
Analog and RFIC design support
I help semiconductor teams move from early feasibility and RF system definition to circuit implementation, EM modeling and lab validation. My work spans automotive, radar, phased array, RFIC, MMIC and mixed-signal ICs up to 120 GHz.
