What we do

Hardware, firmware, and HMI, under one roof.

We design the electronics, write the firmware, build the touchscreen interface, and ship the product. No vendor hand-offs, no integration debt. One team owns concept through manufacturing.

The team

Mechatronics & senior embedded engineering.

Two disciplines that usually live in different companies. Mechatronics for the boards, the sensors, the motion. Senior embedded for the firmware that runs on them: RTOS scheduling, peripheral drivers, OTA, secure boot. Hire one team; ship one product.

Embedded systems technical work
Mechatronics engineering
Skilled engineers for critical gaps: contract capacity, interim coverage, or full-time project-driven technologists.
Senior embedded systems
RTOS scheduling, peripheral drivers, OTA pipelines, and secure boot. Production firmware for devices that ship and stay alive in the field.

How we're different

Four concrete commitments.

Bare-metal to Linux, in-house

RTOS architectures, embedded Linux (Yocto/Buildroot), and bare-metal MCU firmware. One team owns the full stack.

Production-ready hardware

PCB design through DFM hand-off. Schematics, layout, BOM optimisation, and contract-manufacturer-ready Gerbers.

OTA built for the field

Field-proven over-the-air update pipelines and secure boot chains. Devices stay current and authenticated after deployment.

24-hour reply, fixed-fee scoping

Reply within one business day. Fixed-fee feasibility studies before larger engagements. No open-ended discovery contracts.
