Device firmware and hardware engineering for connected products.

From board bring-up to volume production. We design, debug, and harden the firmware and hardware of IoT devices for teams shipping at scale.

What we do

Engineering services for the device layer.

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.

Embedded Firmware

Bare-metal and RTOS development in C/C++. Drivers, HALs, bootloaders, OTA update design, and register-level debugging on real hardware.

Board-Level Hardware

Schematic and layout review, component selection, board bring-up, and hardware/firmware co-debug when the prototype misbehaves.

Sensors & Peripherals

I²C, SPI, UART, ADC integration. Low-power sensor subsystems and clean on-device data handling.

Power & Battery Life

Sleep/wake architecture, energy profiling, and battery-budget engineering for devices that must live years on a cell.

Reliability & Field Failures

Root-cause analysis of devices failing in the field: environmental, electrical, and firmware-interaction failures. DFM/DFT for the next revision.

Prototype to Production

Taking a working bench prototype to a manufacturable product: design hardening, test strategy, and contract-manufacturer coordination.

How we work

A short path to useful work.

Straightforward scoping, honest proposals, and hands-on engineering.

Scope

A focused technical conversation about your device, your constraints, and what done looks like.

Plan

A concrete proposal: what we'll build or fix, how we'll verify it, and what it costs.

Build

Hands-on engineering with direct communication — working firmware and findings at every milestone.

Harden

Verification on real hardware, documentation your team can own, and a clean handoff.

Operating principles

How we run engagements.

The IoT Firmware Field-Reliability Checklist

Twenty-two checks that separate a build that passes on the bench from firmware that survives a fleet in the field. Tell us where to send it.
