FIRMWARE.
A blinking prototype is not a product. NAK writes embedded firmware that gets connected devices through board bring-up, demos, test fixtures, manufacturing, and field updates without turning every hardware quirk into a support problem.
We work where firmware usually bites: timing, memory, interrupts, battery life, drivers, radios, boot paths, diagnostics, update behavior, and recovery. The work is practical because customers do not care which layer failed. They care that the product failed.
If the device works sometimes but not reliably enough to ship, firmware is probably where the truth is hiding. We help find it, fix it, and leave your team with code they can live with after launch.
