Bare-metal and RTOS firmware
Deterministic, memory-bounded C and Rust with power budgets that let battery devices last their rated life.
Infrastructure
Firmware that runs for years untouched.
Bare-metal and RTOS firmware, secure connectivity, and over-the-air updates for fleets you can't physically reach.
Discuss this project
10–16 weeks from bring-up to field-ready
The short version
Embedded software fails differently. There's no refresh button on a sensor in a field, a memory leak surfaces after four months of uptime, and a bad firmware push can brick a thousand units at once.
We build for those constraints: bounded memory, watchdogs, brownout handling, and update paths designed to fail safe. Devices come online with signed firmware, report health, and can be updated over the air without a truck roll.
Typically built with
C C++ Rust FreeRTOS Zephyr MQTT Go TimescaleDB
What's included
How we approach embedded systems development
Connectivity that copes
MQTT, BLE, LoRa and cellular with store-and-forward buffering for the long stretches with no signal.
Safe over-the-air updates
Signed images, A/B partitions and automatic rollback, so a bad release can't brick the fleet.
Fleet visibility
Device health, firmware versions and telemetry in one dashboard, with staged rollouts by cohort.
What you get
Delivered at the end
- Production firmware with source and build toolchain
- OTA update infrastructure with signing and rollback
- Fleet management dashboard
- Hardware bring-up notes and test procedures
Right fit
This is for you if
- 01 Hardware startups moving from prototype to production
- 02 Existing devices that need connectivity or OTA
- 03 Fleets managed today by spreadsheet and site visits

A clear path from idea to impact
- 01
Discover
We map your goals, users, and constraints into a sharp, prioritized scope.
- 02
Design
Architecture and interfaces are prototyped and validated before a line ships.
- 03
Build
Engineers deliver in tight sprints — you see working software every week.
- 04
Scale
We launch, monitor, and harden — then grow the system alongside your business.
Questions
What clients ask about embedded systems development
The things that come up most on the first call. Anything else, just ask — we answer straight.
-
Do you design hardware too?
We do the firmware, connectivity and cloud side, and work alongside your hardware engineers or EMS partner. We'll review schematics from a firmware standpoint and flag problems early, but we don't lay out boards.
-
How do you test without the full fleet?
Hardware-in-the-loop rigs plus simulated fleets for the cloud side. OTA rollouts then go out in staged cohorts, so a problem hits a handful of devices rather than all of them.
-
What about security on devices in the field?
Secure boot, signed firmware, per-device credentials and encrypted transport as the baseline. A device you can't physically protect has to assume someone will try.
