The end-to-end chain
A connected system is a chain: if one link is weak, everything fails. I follow the whole chain, from the device to the applications, which means a single point of contact.
- 01
Device
ARM Cortex-M / Cortex-A, STM32, NXP, ESP32
- 02
Firmware
C / C++, FreeRTOS, Embedded Linux (Yocto, Buildroot)
- 03
Protocols
MQTT, Modbus, CAN, RS-485, NFC, BLE
- 04
Cloud
Node.js, Django, PostgreSQL, InfluxDB, AWS, Docker
- 05
Applications
React, Qt, Flutter (Android, iOS, Windows, Linux)
Less friction between teams
Firmware, backend and apps are designed together, with no finger-pointing.
Clear responsibilities
I know what happens at every point of the chain and I answer personally for the result.
Consistent architecture
Protocols, data and interfaces come from one technical vision.
Services
Three ways of working together, depending on where my contribution is needed.
Fields of experience
Systems that work in the field every day, in sectors where reliability is not negotiable.
Payment systems
Cash, NFC cards and e-wallets, integrating validators and readers into one consistent system.
