I'm excited to share Daymark, a productivity web application I've been building to make everyday note-taking and task management simple, accessible, and reliable — even without an internet connection.

**What is Daymark?**

Daymark is an offline-first, local-first Progressive Web App (PWA) designed to help users organize their daily work through:

- 📝 Notes management

- ✅ Task management and organization

- 📁 Folders and tags

- 🔍 Search, archive, and trash

- 💾 Local data persistence

- 📶 Offline access through service worker caching

- 📦 JSON backup and restore

**Technology Stack**

React 19, TypeScript, Vite , Zustand, Dexie.js, IndexedDB, Tailwind CSS, Workbox, Vitest and Playwright.

🔗 GitHub: [https://github.com/ARUNAGIRINATHAN-K/daymark](https://github.com/ARUNAGIRINATHAN-K/daymark.git)

🌐 Live Demo: [https://daymark-umber-nine.vercel.app/](https://daymark-umber-nine.vercel.app/)

Daymark uses local-first architecture, storing data in-browser via IndexedDB for offline note/task operations. I've also built syn queue and conflict management for future sync. I'm improving the app, refining architecture, strengthening testing, and exploring enhancements. 

Building Daymark taught me modern frontend tech, browser storage, offline-first architecture, and PWA development. Feedback welcome!
