Expertise
Grouped by the kind of evidence behind each claim rather than by a proficiency rating. A percentage next to a technology would tell you nothing; where the evidence comes from tells you something.
Professional practice
Done repeatedly, in shipped industrial hardware.
High-speed & mixed-signalControlled impedance, differential signalling, stack-up, termination and interconnect.
Signal & power integrityPower distribution architecture, sequencing, startup behaviour, inrush and pre-bias.
EMC / EMIDesigned in from architecture and layout, not tested at the end.
Camera & sensor electronicsSensor interfaces, high-speed image data paths, triggering and synchronisation.
Bring-up & validationMeasurement-driven debugging, root-cause analysis, product verification.
Design for manufacturingProduction constraints, component availability, documentation, lifecycle workflows.
