Tell me what you're building. I'll get a working prototype in your hands.
I'm an electrical engineer who does the whole job: schematic, board, firmware, and the bench work in between. You talk to me, not an account manager. We start with a short call, then I break your project into two phases so you get a working prototype before committing to a full build.
How it works
Every project is different, so I don't quote the whole thing up front. I split it in two:
Phase 1: Discovery, feasibility, bench prototype (usually 2 to 4 weeks)
Figure out what has to be true for this to work, then prove it on the bench with dev kits, modules, and whatever gets a real answer fastest. You get:
- A working bench prototype that does the core thing
- A short write-up of what worked, what didn't, and what it means
- Part and architecture direction with a rough BOM cost
- A Phase 2 quote based on what we learned
Phase 2: Custom board, firmware, first units (usually 6 to 10 weeks)
Turn what Phase 1 proved into a real board: schematic, layout, firmware, first units assembled and tested on my bench. You get:
- Assembled, tested prototype boards
- All source files: schematic, layout, firmware. You own them.
- A test procedure and a plan for production if that's where it's going
Between phases: you decide. If Phase 1 says "don't build this," you find out for a fraction of the cost and keep everything.
How it starts
- Email me. A paragraph on what you want to make or what's stuck. Sketches, datasheets, or a half-finished board are fine.
- We talk. 30 minutes. I'll ask what it has to do, what it can't cost, and what done looks like. If I'm the wrong person for it, I'll say so.
- You get a proposal. Within two business days: scope, deliverables, timeline, and price for Phase 1, plus a range for Phase 2.
What I do
Hardware
- Schematic and PCB layout in Altium: mixed-signal, multilayer, flex and rigid-flex
- Power: batteries, chargers, power path, DC-DC, high-voltage and isolation
- Motor drivers (BLDC, stepper), LED drivers, analog front ends and precision measurement
- BLE / 2.4 GHz RF integration, sensor interfaces, data acquisition
- EMC-aware layout, filtering, shielding, thermal
Firmware
- Bare-metal C on STM32, Silicon Labs EFR32/BGM13S, Nordic nRF52/53, ESP32, AVR
- FreeRTOS and Zephyr; bootloaders and OTA/DFU updates
- BLE and WiFi stacks, sensor drivers (I2C/SPI/UART), motor control
- Low-power design and sleep-current optimization
- Embedded Linux / Raspberry Pi; Python for tooling and test automation
Getting it built
- Design for manufacturing and test; BOM alternates and second sourcing
- Functional test fixtures: bed-of-nails hardware and fixture firmware
- Fab and assembly vendor management, first-article review, customs and import
- Medical devices: IEC 60601-1 / -1-2, CB Scheme, EMC testing at SGS, ISO 13485 production
Prototyping in-house
- Bench rework and hand SMT assembly
- Enclosures in Fusion 360; 3D printing, CNC, laser cutting; cable and harness design
What I've done
- 15+ years of electronics product development; thousands of boards designed and built
- Medical device electronics through IEC 60601 and EMC testing, ISO 13485 production
- Coordinated a production run of tens of thousands of units from fab through customs
- Medical, consumer lighting, IoT / smart home, and industrial products shipped
Not a fit
I don't take software-only or app-only projects, FPGA/ASIC work, pure mechanical design, or high-volume consumer products chasing the last penny of cost. If that's what you need, I'll tell you on the call and point you somewhere better.
