Freelancer profile translated to English.
Back to original languageAbout Lucas
I work on C firmwares (existing or to be developed), typically on STM32, FreeRTOS/RTOS, CAN to deliver stable and diagnosable products.
Typical cases:creation of a clean firmware base, bring-up, adding features without regression, field resets/freezes, unreproducible bugs, unmanageable legacy, MCU migration.
Result:fewer field/after-sales returns and "reduction of diagnostic time from ~30 min to <5 min.
Format:predominantly remote, short phases: 2-day audit -> sprints -> milestone execution.
👉 Tell me:MCU, RTOS, symptoms (or product objectives), constraints, and I'll propose the right framework.

Experience
- SyloriaFirmware Freelance | Diagnostic & StabilizationSOFTWARE PUBLISHINGOctober 2025 - Today (8 months)Bordeaux, FranceInterventions on existing firmwares (prototype or legacy) to make them diagnosable (we understand the cause of failures) and stable (hardened critical paths).Case studies:
- Prototype -> pre-series (STM32): hardening + MISRA-C 2012 compliance (MISRA = industrial C code rules), error/timeout management, SPI Flash storage (SPI = serial bus), JSON flux (JSON = structured text format).
- J1939 Migration (J1939 = vehicle/industrial CAN protocol): porting a legacy "8 bytes" stack to a 16-bit MCU with byte-level abstraction (byte-level = byte access).
- UDS Diagnostic (UDS = vehicle diagnostic protocol): instrumentation (cause of reset, persistent error codes, minimal logs) + root cause method to reduce field diagnostic time.
Delivered value:less time wasted on diagnostics, fewer avoidable incidents, and a maintainable base to accelerate evolution. - SharkRoboticsEmbedded Robotics EngineerAUTOMOBILESeptember 2022 - September 2025 (3 years)La Rochelle, FranceIntegration of STM32 drivers in C, CAN communication (CAN = industrial bus) and sensor interfaces in a FreeRTOS environment (RTOS = real-time operating system).Design and development of a 48V/20A BMS (BMS = Battery Management System) on STM32: schematics + PCB (KiCad), C firmware, INA228 current/voltage measurement on CAN, good EMC practices.ROS2 development for robotic platforms: standardization of software components (cost reduction ~30%).
