Battery-powered device optimization
We profile and tune power consumption so your device lasts months or years on a battery instead of days.
- Power profiling & current budgets
- Sleep modes, wake sources, duty cycling
- Radio & peripheral power tuning
Embedded services · Consumer · IoT · Cloud
Firmware and connectivity for products that run on a battery and talk to the cloud.
We're a complete embedded team (3 engineers and a dedicated QA) building and maintaining connected consumer and IoT devices for companies in the US and EU. From requirements to field updates, we can own the whole lifecycle or take over a project already in progress.

Services
What we build
Device firmware, the wireless link and the cloud side, built by one team so the pieces fit together.
Bluetooth & wireless connectivity
BLE and Classic Bluetooth, UWB ranging and NFC, including custom GATT services and standard profiles.
- BLE: GAP, GATT, custom services
- Classic: A2DP, AVRCP, HFP/HSP, HID, PAN, MAP, OPP, PBAP
- UWB positioning, NFC pairing
OTA updates
Firmware updates that are safe to ship: signed images, rollback, and delivery over BLE or the cloud.
- Bootloaders & A/B image swap
- Image signing & verification
- Staged rollouts, recovery paths
Cloud & device communication
MQTT pipelines and cloud apps that provision, monitor and control your devices in the field.
- MQTT, TLS, device provisioning
- Telemetry, commands, device shadow
- Dashboards & backend services
Wireless charging
Firmware for the charger and receiver sides, covering charge control, device detection and thermal protection.
- Charging state machines
- Foreign object & thermal handling
- Integration with battery management
Project takeover
If your product is stuck, or the previous vendor has left, we audit the codebase, stabilize it and carry it through to launch.
- Code & architecture audit
- Knowledge transfer & documentation
- Stabilization roadmap

Industries
Where our experience comes from
We've worked in industries that don't tolerate field failures, and we bring those standards to consumer products.
Connected consumer devices
Wearables, audio, smart home and personal devices that pair with a phone app, update over the air and run for a long time on a small battery.
Automotive-grade discipline
Automotive work taught us to write down requirements, trace them through the code and test everything, and we work that way on every project.
Security by design
We plan secure boot, signed updates, encrypted links and key handling from the first architecture draft.
Connected monitoring devices
Monitoring devices that pair with a phone and cloud apps and update over the air.
IoT monitoring services
Cloud services that monitor IoT devices in the field.
Full SDLC & product management
One team, from idea to field
You can hire us for a single phase or for the whole lifecycle. Either way, one team is accountable from start to finish.
