About

I'm a Product Engineer graduating from ECE Paris (Product Engineering & Innovation), with international experience across Europe and Asia — including an exchange semester at NTUST in Taiwan and currently completing a Product Manager internship at Rakuten in Paris.

I sit at the intersection of engineering and product: I can write the code, design the system, and ask whether we should build it at all. My projects span AI tooling, IoT systems, full self-hosted infrastructure, and game dev.

I'm also self-studying Japanese (≈ N3) and have a strong drive to work in Japan.
