Board bring-up.
Get a new board to first signs of life without guessing: power checks, bootloader setup, peripheral validation, and enough firmware to prove the hardware is worth building on.
NAK Engineering / Firmware
Firmware that makes hardware worth shipping.
A prototype can blink an LED and still be miles from a product. NAK writes the embedded firmware that gets connected devices through bring-up, demos, test fixtures, manufacturing, and field updates without turning every hardware surprise into a schedule fire.

Product promise Something customers can trust
Why teams call us
The hard part is not the demo. It is everything after the demo.
Firmware is where hardware decisions become user experience. If timing drifts, batteries die early, radios drop, updates brick devices, or factories cannot diagnose failures, customers do not blame the microcontroller. They blame the product.
We help when a team has real hardware on the bench, a launch date getting closer, and too much risk hiding in the device layer. The work is practical: readable state machines, measured timing, recoverable boot paths, useful logs, and tests that catch the boring failures before users do.
Capabilities
Firmware help where connected products usually get stuck.
RTOS and bare-metal firmware.
Write embedded C and C++ for the constraints that actually bite: timing, memory, interrupts, battery life, and systems that need either a bare-metal loop or a real RTOS.
Drivers and protocols.
Make sensors, radios, displays, motors, storage, and custom silicon behave predictably, then expose clean interfaces for the app, cloud, or test bench.
Power and performance tuning.
Measure on the real device, then tune latency, sleep states, throughput, and failure cases instead of hoping the bench demo survives a customer environment.
Secure update paths.
Design update, rollback, signing, and recovery behavior before devices leave the building, because field fixes should not depend on a screwdriver and luck.
Test and production readiness.
Add diagnostics, factory hooks, validation fixtures, and repeatable tests so the firmware helps manufacturing find problems instead of hiding them.
Lifecycle
Plan for the product you will have after launch.
The first version only proves the idea. Then parts change, edge cases show up, manufacturing needs faster checks, and customers expect safe updates instead of recalls. We build firmware with that next phase in mind, so the codebase does not become a trap the moment the product works.
