Overview
What I built & why
Open source note-taking and to-do app with end-to-end encryption sync. Desktop, mobile, and CLI clients all share the same SQLite store.
Designed for users moving away from Evernote, with one-click import.

Process
Challenge & solution
The challenge
A patchwork of spreadsheets and three different inboxes meant nobody knew the real status of a job until the customer complained.
The solution
Rebuilt the front-end around mobile-first layouts, prefetching, and aggressive image optimisation — the new TTI is under one second.
