Mechatronics Engineer | Hardware, IoT & Battery Systems Expert
Need to transform a complex technical idea into a tangible and functional product?
Mechatronics engineer with 6 years of experience in industrial R&D, I will guide you through the entire hardware product development cycle. My specialty? A "Full-stack Hardware" approach, combining electronics, mechanics, and embedded software under a single expertise.
🛠️ What I can bring you:
From Proof of Concept (PoC) to industrialization, I intervene to overcome your technical challenges:
Electronics & IoT: Design and routing of complex PCBs (Altium Designer, KiCad). Integration of sensors (IMU, pressure) and connected solutions.
Mechanics & CAD: Advanced 3D modeling (Fusion 360, SolidWorks), design of waterproof enclosures and articulated robotic systems.
Li-ion Battery Expertise: Complete custom pack design, BMS management, and validation through safety tests (charge/discharge, shock, vibration).
Embedded Intelligence: Firmware development (C/C++, Python, STM32) and advanced features (OpenCV, face tracking).
🚀 My added value:
"Maker" Culture & Rapid Prototyping: I have my own equipped workshop (FDM, SLS, CNC, laser cutting). This allows me to deliver functional physical prototypes in record time.
Global Product Vision: I design electronics with consideration for mechanical integration and robustness in demanding environments (outdoor, sport tech).
Critical Systems: From batteries to high-power electric vehicles (motorcycles, eFoils), I master power and safety challenges.
📦 Typical deliverables:
Complete manufacturing files (Gerber, BOM, CAD files).
Documented and optimized firmware source code.
Assembled functional prototypes for your testing or fundraising.
