Hi, I'm Jaylen. I build test automation and internal tooling for other engineers.
In QA and test engineering since 2018, most of it spent building the tooling rather than running the tests.

Recent work
A few of the things I've been building lately, mostly on nights and weekends.
nas-media-pipeline
A toolkit that pulls public-domain media off the Internet Archive, quarantines anything dangerous, verifies it byte-for-byte onto the NAS, and renames it into the layout Jellyfin expects.
PokePlaybook
A SwiftUI app for building and analyzing competitive Pokémon teams, with live type coverage, a full Pokédex, and an AI review that tells you what the team is missing.
jaylen.dev
A personal site built on Next.js 16 and Tailwind 4, with every piece of content kept in typed files that tests can check before a build ships.
