Hi, I'm Raphael! 👋

Full-stack developer with a background in Big 4 Tax consultant (Deloitte) and a Le Wagon graduate (Mar 2026).

At Le Wagon Tokyo, I built Dōjin Master and PR Tomo: full-stack apps with Rails, PostgreSQL, and JavaScript, with 3 colleagues.

I now focus on Node.js, React, and TypeScript, building full-stack applications on the JS stack.

I'm currently working on Forin: a platform to analyze trends on foreigners living in Japan. If you are a foreigner living in Japan, I'd appreciate your input in the surveys.

Check out my pinned repos or my portfolio to learn more about my projects.

You may reach me at [email protected] or via LinkedIn.

My stack:

JavaScript Node.js React TypeScript Ruby Rails PostgreSQL MongoDB HTML5 CSS3
