About EFH

Built for engineers,
by engineers.

EmbeddedFirmwareHelper (EFH) is a firmware engineering company focused on one thing: building production-quality embedded software that ships reliably. We work with hardware teams who need firmware expertise without the overhead of building an in-house team.

Our work spans bare-metal Cortex-M firmware, RTOS-based architectures, communication protocol stacks, and full IoT device pipelines — from PCB bring-up to cloud connectivity.

✓
Production-grade firmware — not prototypes
✓
Architecture-first approach with documented interfaces
✓
Reusable IP stacks available for licensing
✓
Technical depth across MCU, RTOS, and connectivity layers
