Maxence Fromentin — I write the code, design the system, and ask whether we should ship it at all. Now looking for an AI engineer role in Japan.
At Rakuten, I spent six months on one question: why don't first-time buyers come back? Cashback existed — customers just waited up to 45 days and never noticed. I made it land instantly and put the balance in the header, where people decide. Three months later: +10% repurchase rate.
The build matters, but so does whether anyone understands it. ECE Paris '26 (Product Engineering & Innovation), with semesters in Malta and Taiwan. Two years of daily Japanese, targeting JLPT N3. Available now.
Full-stack Japanese learning platform: React 19 + Vite front end, FastAPI back end, and Supabase Postgres with row-level security. Vocabulary and grammar drills are generated by Mistral AI, with a local Ollama model kept as a fallback.
Privacy-first local AI assistant powered by a 0.5B LLM — no external APIs, all inference runs on-device ensuring zero data leaves the machine.
Raspberry Pi–hosted web app that automates irrigation by controlling solenoid valves based on real-time data from 15 soil sensors.
Full self-hosted homelab: Home Assistant for automation, n8n for workflow orchestration, NAS for storage, WireGuard VPN, and multiple VMs.
Managing cross-functional technical projects with engineering teams, ensuring timely delivery. Coordinating product delivery across engineering, design, and business stakeholders. Gaining hands-on exposure to e-commerce platform architecture and transactional systems.
Courses in Advanced Modern Networking, AI Technologies & Business Applications, Ergonomics in Design, Global Marketing Management, Mandarin, and Japanese.
Designed and developed a Python-based HMI to support engineers in ADAS washing circuit design. Implemented automated calculation and visualization features, significantly reducing manual workload and accelerating design processes.
Built and delivered a fully functional website aligned with strict client requirements and timelines, working closely with a cross-functional team.
Courses in Management, Engineering Drawing, and NLP / human-computer interaction.
Specialization in Product Engineering & Innovation (PEI). Courses include UX/UI design, Web & Mobile Development, Project Management, HMI, and Gamification.
“Intellectual curiosity and a drive to understand the full picture — from user problems to technical constraints.”
“Work ethics, oversized curiosity and overall resilience. Any team would benefit from Maxence joining their ranks.”
