Embedded systems & mechatronics engineer, based in Paris.
I make silicon move things. Come on in, the terminal's warm.

Elegoo Neptune 4 on Klipper. Prints robot parts, enclosures,
and the occasional plate of spaghetti. PETG and I are still negotiating.

Cats: the only coworkers allowed to walk on my keyboard.
Got one? Send a picture, I mean it.

Embedded, robotics, medtech. And a good chat about any of them._| Project | What it does | Stack |
|---|---|---|
| Myoelectric hand prosthesis | Final-year project: EMG acquisition and embedded signal processing driving tendon-actuated fingers. It didn't fully work, and it taught me more than the projects that did. | STM32, C, EMG front-end |
| STM32 validation lab | Personal test automation platform for Arm Cortex-M validation. Caught a DMA glitch on circular ADC transfers and an MDF clock inconsistency. | HAL/LL, ST-Link, oscilloscope, logic analyzer, Python |
| AN5795 contribution | That MDF clock finding became a correction to an official STMicroelectronics application note. | STM32 MDF, documentation |
| ST Wiki: FIR Signal Processing | Official ST tutorial I wrote: a real-time ADC → FIR → DAC pipeline on STM32C5, DMA double-buffering, CMSIS-DSP. | STM32C5, NUCLEO-C562RE, CMSIS-DSP |
| ST Wiki: GPDMA and Linked-list | Official ST tutorial I wrote: chaining autonomous DMA transfers through linked-list nodes, zero CPU involvement. | STM32H5, GPDMA, STM32CubeMX |
| 30 jours de STM32 | Public LinkedIn series: one STM32 concept a day, explained from scratch. | Teaching, STM32 |
Currently building: BMS-VirtualLab, a battery state-of-charge estimator (Extended Kalman Filter on a 2RC model, validated on real LG 18650 data), and a humanoid robot built from recycled printer parts.
