About me
I'm a full time electronics engineer and I'm new to freelancing. My day job is PCB layout and firmware, mostly STM32 and FPGA boards. Most of what I do is power and motor drive. Buck converters, stepper drivers, LED drivers. The most complex board I've built is a 6 layer around a 169 ball BGA, driving four channels at 10 A each, with Ethernet. I work in KiCad. Before anything leaves I run DRC and ERC clean and check the routed board against the schematic, so what you fab is what you drew. You get the project files, not just the outputs. If your fab flags anything, I'll fix it.... Read more

Designed a 6-layer power board around a 169-ball BGA FPGA, delivering 40 A total at 24 V across four channels in a tight footprint; split the power plane into four while keeping the ground plane solid, with 2 oz inner copper on the high-current paths. Released 10 production boards end to end (schematic, layout, BOM, fab package), including a 4-layer STM32H5 high-current controller, a circular LED array, and a multi-protocol control board with RS-485, Ethernet, and I2C on a 24 V rail. Designed and wrote the firmware for a daisy-chainable 4-axis stepper motor control board (STM32H5) in a $450,000 inspection machine; the master's non-standard I2C meant writing bare-metal I2C with a custom address-arbitration algorithm. Worked with the mechanical team to check board outlines and mounting holes against the enclosure before release. Collaborated with the software team to integrate the board firmware with the machine's user interface. Recognized at annual review for full-cycle turnaround speed, schematic to fab-ready. Replaced a hardware-controlled PIC32 with an STM32 slave, writing register-level SPI code fast enough to answer the master within the same SCK cycle.
