I’m a Mechatronics Engineer focused on where software and hardware converge. I build embedded firmware for industrial IoT systems and pair it with Python backends that turn telemetry into cloud-ready, decision-ready data.

At SEINTMA SAS, I developed real-time firmware on ESP32 using FreeRTOS (dual-core), integrating industrial sensors, GSM/LTE modems (A7670) via AT commands, and SD card management over dedicated SPI buses (SdFat). I also built monitoring systems for Slick Line and Wire Line operations, including efficient 12-byte binary serial telemetry for field-to-system transmission.

I bring strong control and hardware design experience: I implemented movement sequences for telescopic cranes and CAN/CANopen control systems for manlift and industrial crane equipment. I also designed PCBs in EasyEDA under industrial and electrical standards for Raspberry Pi-based embedded systems, and created a Unity/C# crane simulator to support operator training and validation.

On the data and integration side, I model and persist industrial datasets with SQL scripting (e.g., Hook Load indicator logging) and deliver cloud pipelines with Python ETL into Azure services. In parallel, I integrated the Siigo API, automated reporting/notifications, and processed bulk accounting movement data from XML, PDF, and Excel to keep financial provisioning timely.
