About Me
🧑💻 I’m a Full-Stack Developer who enjoys building end-to-end web applications that are fast, scalable, and user-focused. I’ve collaborated with developers from over 10 nationalities, gaining experience in both front-end and back-end development while learning to turn complex ideas into reliable digital products.
🎓 I hold a B.Sc. in Digital Business & Innovation from Tokyo and graduated from Le Wagon’s Full-Stack Web Development Bootcamp, where I built and deployed 5+ applications including an AI-powered FinTech platform.
⚙️ My core stack includes Ruby on Rails, JavaScript, React, Python, and PostgreSQL. I’m also experienced with AWS, DevOps, and CI/CD pipelines.
🤖 I build data-driven web applications that combine clean engineering with modern AI integration. From AI-powered features like RAG and Embeddings to scalable automation, I design systems that learn, adapt, and scale—bridging full-stack development with AI innovation.
