About
At Rakuten, I spent six months on one question: why do first-time buyers not come back? The answer wasn't a missing feature. Cashback already existed — customers just waited up to 45 days to get it, and most never realized they were earning it at all. I made it land instantly, the moment the package hits the mailbox, and put the balance in the site header where people actually decide. Three months later: +10% repurchase rate.
That's the pattern I keep coming back to — the build matters, but so does whether anyone understands it. I write the code, design the system, and ask whether we should ship it at all. IRIS runs a 0.5B LLM fully on-device because I wanted zero data leaving the machine, which meant actually learning tokenization and quantization instead of calling an API. My irrigation system reads 15 soil sensors off a Raspberry Pi. My homelab runs Home Assistant, n8n, a NAS, and WireGuard, and I maintain all of it.
Graduated from ECE Paris in 2026 (Product Engineering & Innovation), with semesters in Malta and Taiwan along the way. Now looking for an AI engineer role in Japan — not a vague preference: two years of daily Japanese study, targeting JLPT N3, available to start.

Recommendations
What stood out most throughout the six months was Maxence's intellectual curiosity and his drive to understand the full picture — from user problems to technical constraints.
Margaux BobinProduct Manager, Checkout & Loyalty · Rakuten FranceMy manager during my six-month Product Manager internship, Jan–July 2026.
“He identified the opportunity, drove it forward, and delivered improvements that had a real effect on the product.”
“He handled these high-visibility moments with confidence and clarity.”
“Always willing to help, share information, and make himself available — qualities that made him a trusted and well-liked member of the group.”
“I had the opportunity of working with Maxence when he was interning in the Product organization I led at Rakuten France.
Maxence impressed us with his work ethics, his oversized curiosity and overall resilience. He is a promising Product Manager with all the right tools to reach his goals and achieve success in his next endeavour.
Any team would benefit from Maxence joining their ranks!”
