Dawna Daigneault, a self-worth coach, had a Figma Make prototype of a guided self-worth journaling app: exercises across four pillars, a daily journal with mood tracking, an affirmation deck and milestones. As sole engineer I hardened and deployed the web PWA, then ported it to a native Expo app with on-device storage, iPad layouts, haptics and animation.
Analytics are metadata-only and never capture journal or affirmation text. Updates ship over the air with an in-app restart prompt. I also handled the signed Android releases, store listings and data-safety forms, and fixed a silent OTA failure caused by runtime-version drift.
