Interactive architecture

A frontend is a living system.

Move through the layers—or hover the 3D nodes—to see how I connect interface, state, and services.

Selected work

Products built around real decisions.

Three real product builds spanning emissions analytics, privacy-first local AI, and interactive geospatial comparison.

Engineering with context

I build the bridge between product intent and production code.

I have delivered enterprise frontend work for Bridgestone, built reusable components and custom hooks that reduced development time by about 30%, and mentored junior developers and interns. My current Master’s work extends that product background into AI, data analytics, RAG, and cloud technologies.
