// 01 Core expertise

What we build, end to end.

Firmware delivered as a complete engineering practice: architecture, integration, security, and maintainability. Built to survive field conditions and audits.

01

RTOS Architecture

Modular firmware design with Zephyr, NuttX, and FreeRTOS on ARM Cortex-M, Xtensa, and RISC-V MCUs.

02

Secure Bootloaders & OTA

MCUboot multi-partition with RSA/ECDSA signing, AES/ECIES encryption, and proprietary update channels (CAN, RS-485, UART, SD Card).

03

Industrial & IoT Protocols

CAN-FD, CANopen, J1939, Modbus, DNP3, MDB, ISO-TP, Zigbee, LoRa, integrated and production-ready.

04

Embedded UI & Remote Access

LVGL and TouchGFX on RGB (LTDC) and SPI touchscreens, plus VNC server for remote control.

// 02 How we work

Three phases.
Zero surprises.

01

Requirements & Architecture

Understanding the problem before writing a single line. Risks mapped, interfaces defined, partitioning decided.

02

Build & Integrate

Modular firmware with automated testing and reviews. Incremental merges into a working device from week one.

03

Delivery & Handover

Production-ready code plus training and documentation. Your team owns the codebase, not the consultant.
