About François Guéguen
I build products and solve customer deployment problems directly with product and engineering teams.
Experience
I am a French software engineer based in Japan with more than 15 years of experience across product engineering, startups, developer tooling, language systems, and TypeScript-heavy platforms.
I am most useful when a project crosses boundaries: understanding the workflow, making product decisions, building the system, finding failure modes, and handing it over clearly.
Languages and location
I work in English and French and hold JLPT N2. That supports day-to-day Japanese communication, but I do not present myself as a native Japanese negotiator.
I work remotely with international teams and can overlap with Japan, Europe, and part of the US working day.
