Setlist and Fennevia are my two main projects: a public music-search service and a modular four-edge shell for stock Firefox. Dial Canvas is the smaller Firefox-first experiment alongside them. All three are public and still evolving.
Setlist is a self-hosted search index for VTuber karaoke. It finds public YouTube archives, extracts timestamped song lists from comments, and links each result to the start of the performance.
Architecture
Setlist crosses the whole stack: search UI, ingestion workers, a relational data model, and a deployment I operate on my own infrastructure.
Fennevia is an experimental, content-first interface for stock Firefox. It turns browser chrome into a modular four-edge workspace where nearly every visible control can be moved, nested, or reoriented. A narrow, validated bridge leaves security-sensitive flows with Firefox and can fall back to the retained native interface. The Windows prerelease tracks current Firefox Release builds and is intended for a dedicated profile.
A free-form speed-dial canvas for the new tab page. Dials and widgets can be moved, resized, and arranged without a rigid grid. Data stays local unless optional Firefox Sync is turned on.
The common thread
The shape changes from project to project, but the test is the same: the interface should feel clear, the system should be recoverable, and the maintenance should still make sense six months later.
