From board bring-up to volume production. We design, debug, and harden the firmware and hardware of IoT devices for teams shipping at scale.
Our work is focused on the device itself — the firmware and the hardware it runs on. That focus is deliberate, and it's where field failures are born and battery budgets are won.
Bare-metal and RTOS development in C/C++. Drivers, HALs, bootloaders, OTA update design, and register-level debugging on real hardware.
Schematic and layout review, component selection, board bring-up, and hardware/firmware co-debug when the prototype misbehaves.
I²C, SPI, UART, ADC integration. Low-power sensor subsystems and clean on-device data handling.
Sleep/wake architecture, energy profiling, and battery-budget engineering for devices that must live years on a cell.
Root-cause analysis of devices failing in the field: environmental, electrical, and firmware-interaction failures. DFM/DFT for the next revision.
Taking a working bench prototype to a manufacturable product: design hardening, test strategy, and contract-manufacturer coordination.
Straightforward scoping, honest proposals, and hands-on engineering.
A focused technical conversation about your device, your constraints, and what done looks like.
A concrete proposal: what we'll build or fix, how we'll verify it, and what it costs.
Hands-on engineering with direct communication — working firmware and findings at every milestone.
Verification on real hardware, documentation your team can own, and a clean handoff.
