## Implementation Phases

### Phase 1: Project Setup & Auth (Week 1)

**Goal:** Bootable app with authentication.

1. Initialize Expo project with TypeScript template
2. Install dependencies: `expo-router`, `nativewind`, `convex`, `@convex-dev/auth`, `expo-image-picker`, `react-native-maps`, `expo-location`
3. Configure NativeWind (Tailwind) + constants (colors, Macedonian strings)
4. Set up Convex project & self-deploy
5. Define `schema.ts` with all tables
6. Configure Convex Auth (email/password + phone)
7. Build root `_layout.tsx` with auth state observer
8. Build `(auth)/login.tsx` - email/phone login
9. Build `(auth)/register.tsx` - role selection (handyman/customer) + profile creation
10. Build UI primitives: Button, Input, Card, Loading

**Deliverable:** User can sign up, log in, see role-specific tab layout.

---

### Phase 2: Home & Categories (Week 2)

**Goal:** Browse and discover handymen.

1. Seed `categories` table (Мајстор за сѐ, Водоинсталатер, Електричар, Тескар, Фарбар, Керамичар, Зидар, Градежник, столар, Молер, Електричар, Клима монтажер, etc.)
2. Build `(tabs)/_layout.tsx` - bottom nav (Почетна, Пребарување, Огласи, Чат, Профил)
3. Build `(tabs)/index.tsx` - home screen with hero search + category grid + featured ads
4. Build `CategoryGrid` component with icons per category
5. Build `SearchBar` component with text + location filter
6. Build `(tabs)/explore.tsx` - category list → filtered ad list
7. Build `AdCard` component (image, title, rating, location, price range)
8. Create `ads.ts` Convex queries: `list`, `getByCategory`, `search`, `getByHandyman`
9. Wire up real data to ad listings

**Deliverable:** Customer can browse categories and see handyman ads.

---

### Phase 3: Ad Creation & Detail (Week 3)

**Goal:** Handymen can post and manage ads.

1. Build `ad/create.tsx` - multi-step form:
   - Step 1: Category selection
   - Step 2: Title, description, price range
   - Step 3: Location (map picker or text)
   - Step 4: Availability schedule
   - Step 5: Photo upload (up to 5)
2. Build `ad/[id].tsx` - ad detail page:
   - Gallery, description, location map, availability, rating, reviews
   - "Започни разговор" (Start chat) button
   - "Напиши оценка" (Write review) button
3. Create `ads.ts` mutations: `create`, `update`, `delete`
4. Handle image upload via Convex file storage + `expo-image-picker`
5. Build `profile.tsx` - handyman view with their ads list, edit/delete

**Deliverable:** Handymen can create, view, edit, delete their ads. Customers can view full details.

---

### Phase 4: Customer Posts (Week 4)

**Goal:** Customers can post their needs; handymen can respond.

1. Build `post/create.tsx` - customer need form (title, description, category, location, budget, urgency)
2. Build `post/[id].tsx` - post detail with responses
3. Build `(tabs)/posts.tsx` - feed of open customer posts
4. Create `posts.ts` Convex queries & mutations: `create`, `list`, `getByCustomer`, `close`
5. Add "Одговори на оглас" (Respond to post) flow for handymen → starts a chat

**Deliverable:** Customers post needs, handymen browse and respond.

---

### Phase 5: In-App Chat (Week 5)

**Goal:** Real-time messaging between customer and handyman.

1. Build `(tabs)/chat.tsx` - chat list with last message preview, unread indicator
2. Build `chat/[id].tsx` - full conversation screen with:

   - Input bar with send button + image picker
   - Real-time updates via Convex `onUpdate`
3. Create `chats.ts` Convex queries & mutations: `create`, `listByUser`
4. Create `messages.ts` Convex queries & mutations: `send`, `listByChat` (paginated)
5. Add push notification support via Expo Notifications
6. Add "Започни разговор" button on ad detail → creates or opens existing chat

**Deliverable:** Users can chat in real-time with image support.

---

### Phase 6: Reviews & Ratings (Week 6)

**Goal:** Customer can rate and review handymen.

1. Build `review/create.tsx` - star rating + comment form

3. Pull-to-refresh on list screens
4. Pagination on ad feeds and chat messages
5. Offline-first considerations (Convex optimistic updates)
6. Deep linking configuration
7. App icon & splash screen (Macedonian-themed)
8. EAS Build configuration for iOS + Android

10. Performance audit (list virtualization, image optimization)
11. Accessibility pass (labels, contrast, font scaling)

**Deliverable:** Published app on App Store & Google Play.

## Key Decisions & Notes

- **Language:** All user-facing text is in Macedonian (Македонски). Code variables and comments in English.
- **Role system:** Determined at registration. Handymen see ad creation; customers see post creation. Both can chat.
- **Maps:** Use `react-native-maps` with OpenStreetMap tiles (no Google API key needed for MVP).
- **Convex self-deploy:** Deploy via Docker on own infra for full data sovereignty.
- **Auth strategy:** Start with email/password, add phone OTP via Twilio in Phase 7.
- **Image optimization:** Compress before upload using `expo-image-manipulator`. Max 5 images per ad.
- **Search:** Convex full-text search on ad title/description. Location filter via lat/lng bounding box.
