Software Engineer

First principles, then make.

Rio Miyata

I'm a full-stack engineer with a focus on building web applications that are structured to last. I enjoy working across the entire stack — from crafting intuitive, component-driven UIs to designing backend architectures with clean module boundaries and strong data integrity. What drives me is creating systems where both the user experience and the underlying code are equally well thought out.

Most recently, I built a home-buying simulation platform from scratch, owning the entire stack end to end — designing an API layer with deliberate module boundaries, building the frontend with optimized state management, and setting up secure file handling in the cloud. What I'm most proud of is the investment in long-term maintainability: automated documentation, visual architecture mapping, and coding standards that kept the codebase approachable well beyond the initial build.

Outside of work, you can usually find me soaking in hot springs around Japan, hunting down cozy local cafés, or tinkering with whatever side project has my attention that week.
