About me
Frontend Engineer / Web Developer
I'm Tomokichi, a frontend engineer building apps, blogs, and tools with TypeScript, Astro, and Next.js — and writing about what I learn along the way.
What I Build
- Web apps — practical tools like an AI-powered travel itinerary planner
- Blogs — this engineering log and an active travel blog in production
- Dev tools — small utilities that make everyday development a bit faster
Engineering Interests
- Performance optimization and Core Web Vitals — measure, improve, repeat
- Static site architecture and edge deployment with Cloudflare Workers
- AI-assisted product development and prompt design
- Developer experience (DX) — tooling, linting, build pipelines
- Accessibility and SEO — baked in from the design phase, not bolted on later
Current Focus
- Refining this Astro-based static site — architecture, performance, and SEO
- Expanding Tabidea — an AI travel-planning app built with Next.js and Supabase
