Schematic & PCB Design
Multi-layer boards up to 6 layers with impedance-controlled routing, designed against UL and FCC EMC/EMI and thermal requirements from the first schematic rather than after the first failed scan.
Services
I work with hardware teams and product companies that need a connected electronic product taken from concept to something a contract manufacturer can actually build — and with telecom operators that need the optical layer designed or debugged.
What I do
Embedded Firmware & Bring-up
C/C++ on ESP32, ARM and PIC — ESP-IDF, FreeRTOS, bare metal. Board bring-up, drivers, OTA update paths over LTE or CANBus, and production test firmware.
Optical Systems & Link Design
CWDM/DWDM link budgets, transceiver selection and integration, fibre sensing, and optical performance characterization with OSA, OTDR and power-meter measurements.
EMC Pre-compliance & Debug
Finding why a board fails a scan and fixing it in layout rather than in a shield can. Pre-scan, root cause, and a mitigation plan you can hand to your CM.
How we work together
- Fixed scope
- A defined deliverable with a clear boundary — one board spun, one firmware feature, one EMC investigation.
- Hourly
- Exploratory work, debugging, or design review where the scope genuinely is not knowable up front.
- Retainer
- Ongoing engineering capacity for a team shipping a roadmap of revisions.
Before we start
- Requirements or a functional spec, however rough
- Mechanical constraints and target enclosure
- Target certifications and markets (UL, FCC, CE)
- Expected production volume
- Existing design files, if you are picking up an in-flight project
Next step
Send a short description of the product and where it is stuck. I will reply with whether I am the right person for it, a rough shape for the work, and a quote — or a pointer to someone better suited.
