Precision PCB Heater
CompletedDesigned a PCB heater with thermistor feedback and PWM power control for controlled thermal environments.
Engineering the Physical Layer.
"The physical layer is unforgiving—it demands absolute truth."
I’m an electrical engineer working at the intersection of power electronics, embedded systems, and software. I’ve worked in and led small R&D teams, taking hardware from early requirements and system architecture through design, testing, and commissioning.
My experience includes electrical power systems for LEO satellites at Pixxel, battery management for ground-based energy storage, and grid-tied solar PV inverters at 10 kW and above. That work involves circuit and PCB design, firmware, prototype bring-up, and preparation for manufacture, alongside DFM/DFA, vendor coordination, and reliability analysis through FMECA, FMEA, and worst-case circuit analysis.
I also build the equipment and software needed to understand and verify those systems: electrical ground support equipment, hardware-in-the-loop setups, power loggers, and protection instrumentation. My desktop and embedded software work covers data acquisition, load analysis, billing, and engineering calculations. Alongside development, I’ve advised on spacecraft components and energy infrastructure, working with engineers, researchers, and vendors.
I want to keep doing hands-on engineering while taking products through the full development cycle and leading small R&D teams. I’m also interested in independent projects and collaborations with other engineers and researchers, particularly on hardware and tools that make engineering work easier to carry out, test, and understand.

Radio uses 41% of the average load power.
How this estimate works
Average load = Σ(on-state power × duty cycle). Battery draw = average load ÷ converter efficiency. Runtime = usable battery energy ÷ battery draw. Peak load ceiling assumes every load with a nonzero duty cycle can turn on together; it is measured at the load, before converter losses.
The values are an editable example, not measurements from a project. This simple model assumes constant conversion efficiency and zero off-state power. Enter usable energy after any battery derating; standby draw, temperature effects, startup surges, and changes in efficiency need a more detailed budget.
