About me

Logo Électronique

I transitioned from programming to electronics driven by a simple realization: while software lives only on screens, electronics brings ideas to life in the real world. This passion for creating tangible, functional products shapes my approach to every project.

My focus centers on hardware development, but I believe in complete product realization. From initial concept through PCB design, firmware development, and 3D-printed enclosures, I handle the entire development cycle myself. Each project becomes a comprehensive learning experience, thoroughly documented from conception to completion.

Looking ahead to more demanding fields like high-power LED electronics and FPGA development, I approach each new challenge as an opportunity to build both practical solutions and technical expertise. The goal isn't just to create working prototypes, but to develop full-fledged products that demonstrate the potential of thoughtful hardware design.
