Tomokichi profile

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
