Senior Full-stack Ruby on Rails & AI Engineer

I am a Software Engineer with 5 years of experience building secure, maintainable, and data-driven web applications. I specialize in full-stack architecture, migrating complex legacy processes (like unmanaged Excel data) into modern relational PostgreSQL schemas, and integrating AI workflows. Highlights: - Architected a Rails 8 application migrating legacy Excel datasets into PostgreSQL with real-time visualizations. - Integrated Gemini AI to automate i18n tasks and extract medical data from uploaded images. - Implemented robust authentication systems including OmniAuth integration for Google, GitHub, and LINE.
