Profile01

From idea to production.

I work across the full product lifecycle. I shape the architecture, model data, build APIs and interfaces, automate quality and support every release. I pair technical judgment with product focus to solve real problems and leave foundations that teams can sustain.

Editorial anime discovery archive

  • I design and build an anime archive on top of the official MyAnimeList API, with Next.js and TypeScript, including the hand-written CSS design system and the poster-first editorial interface.
  • I pair incremental static regeneration on the index pages with server-side rendering for search and dossiers. The API key never leaves the server, and a fallback catalogue keeps the site standing when the upstream source fails.
  • I work spec-driven: I document decisions before implementing them and use coding agents to speed up implementation and review.
