Custom firmware development and IoT software architecture
Reliable, secure, and power-optimized software tailored to your hardware’s specific constraints, from low-level drivers to application logic.

Architecture Design
We build modular and scalable firmware architectures that maximize hardware performance while minimizing memory and power footprints.

Connectivity Integration
Expert implementation of wireless stacks (BLE, LoRaWAN, Cellular) ensuring robust data transmission and seamless cloud synchronization.

Security & Updates
Robust implementation of secure boot, encrypted communications, and Over-the-Air (OTA) update systems to keep devices protected and up-to-date.
