+| **Account** | `test@email.com` |
+| **Company ID** | `69dbef4e0917c63d28787737` |
+
+All requests returned **HTTP 200** on every run.

+## Average response time
+
+| # | Endpoint | Method | Avg (ms) | Min (ms) | Max (ms) | Blocks UI? | % of blocking load |
+|---|----------|--------|----------|----------|----------|------------|-------------------|
+| 1 | `/api/v1/tender-approvals/stats` | GET | **614** | 520 | 793 | Yes | 3.4% |
+| 2 | `/api/v1/tender-approvals?limit=10&offset=0` | GET | **16,688** | 16,503 | 17,061 | Yes | **93.6%** |

+| 5 | `/api/v1/tenders/recommend?limit=10&offset=0` | GET | **5,716** | 4,010 | 8,361 | No* | — |
+
+\* Call #5 only fires when call #2 returns an empty tender list. It does not block the initial loading spinner, but still adds server load and may update the list shortly after render.
+
+---
+
+## Totals
+
+| Metric | Time |
+|--------|------|
+| **Sequential blocking total** (calls 1 + 2 + 3) | **~17.9 s** |
+| **Slowest single endpoint** | `GET /api/v1/tender-approvals` — **16.7 s avg** |
+| **Fastest endpoint** | `GET /api/v1/notifications` — **0.5 s avg** |
+
+The home page waits on calls 1 → 2 → 3 in series before rendering. **`/api/v1/tender-approvals` accounts for ~94% of that wait.**

+# Home Page API Calls
+
+Document for the backend team. Describes every HTTP request the mobile/web client fires when the user opens `/home`, including call order, parameters, and what blocks the UI from rendering.
+
+**Context:** Home page load feels slow. The client currently waits on **3 sequential API calls** before showing content. A 4th call runs in the background; a 5th may fire when the user has no "your tenders".
+
+**Base URL:** `https://app.opplenz.com`  
+**Auth:** All requests include `Authorization: Bearer <access_token>`.
+
+---
+
+## Summary
+
+| # | Endpoint | Method | Blocking UI? | When |
+|---|----------|--------|--------------|------|
+| 1 | `/api/v1/tender-approvals/stats` | GET | **Yes** | Always on home load |
+| 2 | `/api/v1/tender-approvals?limit=10&offset=0` | GET | **Yes** | Always on home load |
+| 3 | `/api/v1/feedback?feedback_type=like&limit=1&offset=0` | GET | **Yes** | Always on home load |
+| 4 | `/api/v1/notifications?seen=false&limit=1&event_type=PUSH` | GET | No (background) | App shell mount (parallel) |
+| 5 | `/api/v1/tenders/recommend?limit=10&offset=0` | GET | No | Only when call #2 returns an empty tender list |
+
+**Minimum calls on first load:** 4 (calls 1–3 + 4)  
+**Maximum calls on first load:** 5 (adds call 5 when user has no your-tenders)
+
+**Perceived load time (client-side):** Sum of response times for calls 1 → 2 → 3 (sequential `await` chain).
+
+---
+
+## Call sequence
+
+```
+User opens /home
+│
+├─ [parallel, background] App shell
+│   └─ GET /api/v1/notifications?seen=false&limit=1&event_type=PUSH

+    ├─ 2. GET /api/v1/tender-approvals?limit=10&offset=0   ← await
+    │      └─ if tenders[] is empty (fire-and-forget, not awaited):
+    │         GET /api/v1/tenders/recommend?limit=10&offset=0

+
+## API details
+
+### 1. Tender approval stats
+
+Partnership / self-apply progress rings on the home dashboard.
+
+| Field | Value |
+|-------|-------|
+| **Method** | `GET` |
+| **Path** | `/api/v1/tender-approvals/stats` |
+| **Query params** | None |
+| **Blocking** | Yes — first call in `init()` |
+| **Response fields used** | `data.partnership_count`, `data.self_apply_count` |
+
+**Example:**
+```http
+GET /api/v1/tender-approvals/stats
+Authorization: Bearer <token>
+Accept: application/json
+```
+
+---
+
+### 2. Your tenders (horizontal list)
+
+Main tender carousel and "Your Tenders" section.
+
+| Field | Value |
+|-------|-------|
+| **Method** | `GET` |
+| **Path** | `/api/v1/tender-approvals` |
+| **Query params** | `limit=10`, `offset=0` |
+| **Optional filters** | Not sent from home (`status`, `created_from`, `created_to` are empty) |
+| **Blocking** | Yes — second call in `init()` |
+| **Response fields used** | `data.tenders[].tender` (full tender objects), `data.metadata.pages` (pagination) |
+
+**Example:**
+```http
+GET /api/v1/tender-approvals?limit=10&offset=0
+Authorization: Bearer <token>
+Accept: application/json
+```
+
+**Note:** This is likely the heaviest call — it returns up to 10 full tender objects with nested data.
+
+---
+
+### 3. Liked tenders count
+
+"Liked Tenders" stat card count.
+
+| Field | Value |
+|-------|-------|
+| **Method** | `GET` |
+| **Path** | `/api/v1/feedback` |
+| **Query params** | `feedback_type=like`, `limit=1`, `offset=0` |
+| **Blocking** | Yes — third call in `init()` |
+| **Response fields used** | `data.meta.total` only (client ignores the single returned item) |
+
+**Example:**
+```http
+GET /api/v1/feedback?feedback_type=like&limit=1&offset=0
+Authorization: Bearer <token>
+Accept: application/json
+```
+
+**Optimization opportunity:** Client only needs a count. A dedicated count endpoint (or `meta.total` without loading feedback records) would be faster than a full feedback query.
+
+---
+
+### 4. Unread notification check (background)
+
+Red dot on the notification tab icon.
+
+| Field | Value |
+|-------|-------|
+| **Method** | `GET` |
+| **Path** | `/api/v1/notifications` |
+| **Query params** | `seen=false`, `limit=1`, `event_type=PUSH` |
+| **Blocking** | No — fired from app shell `postFrameCallback` |
+| **Response fields used** | Presence of any result (updates `NotificationStateService`) |
+
+**Example:**
+```http
+GET /api/v1/notifications?seen=false&limit=1&event_type=PUSH
+Authorization: Bearer <token>
+Accept: application/json
+```
+
+Source: `lib/core/routes/app_shell/app_shell_screen.dart`
+
+---
+
+### 5. Recommended tenders (conditional fallback)
+
+Shown when the user has no "your tenders". Replaces the horizontal list label with "Recommended Tenders".
+
+| Field | Value |
+|-------|-------|
+| **Method** | `GET` |
+| **Path** | `/api/v1/tenders/recommend` |
+| **Query params** | `limit=10`, `offset=0` |
+| **Blocking** | No — triggered inside `getYourTenders()` without `await` |
+| **Condition** | Fires only when call #2 returns `data.tenders` empty |
+| **Response fields used** | `data.tenders[]` (full tender objects) |
+
+**Example:**
+```http
+GET /api/v1/tenders/recommend?limit=10&offset=0
+Authorization: Bearer <token>
+Accept: application/json
+```
+
+---
+
+## Pagination (scroll, not initial load)
+
+After the home page renders, scrolling the horizontal tender list near the end triggers additional calls:
+
+| Mode | Endpoint | Params |
+|------|----------|--------|
+| Your tenders | `GET /api/v1/tender-approvals` | `limit=10`, `offset=<page * 10>` |
+| Recommended (fallback mode) | `GET /api/v1/tenders/recommend` | `limit=10`, `offset=<page * 10>` |
+
+Page size is always **10**.
+
+---
+
+## Re-fetch triggers
+
+The full `init()` sequence (calls 1–3, and possibly 5) runs again when:
+
+- User switches away from Home tab and returns to it
+- User navigates to Liked Tenders and comes back (`homeViewModel.init()` on return)
+
+This means the same 3–5 API calls can repeat on every tab switch back to Home.
+
+---
+
+## APIs defined but NOT called on home load
+
+| Endpoint | Notes |
+|----------|-------|
+| `GET /api/v1/feedback/stats/company` | Defined in client (`HomeApi.statsCompany`) but never called from home |
+
+Some home stat cards show hardcoded `0` values (approved tenders count, tender value) — no API backing today.
+
+---
+
+## Performance notes for backend
+
+### Client-side bottleneck
+
+The client **does not parallelize** calls 1, 2, and 3. Total time-to-interactive ≈ `T(stats) + T(your-tenders) + T(liked-count)`.
+
+### Suggested backend investigations
+
+1. **`GET /api/v1/tender-approvals?limit=10&offset=0`** — Likely the slowest call. Check query plans, N+1 joins, and payload size (10 full tender objects).
+2. **`GET /api/v1/tender-approvals/stats`** — Runs before every home load; consider caching per company/user.
+3. **`GET /api/v1/feedback?feedback_type=like&limit=1&offset=0`** — Client only reads `meta.total`. A lightweight `GET /api/v1/feedback/count?feedback_type=like` would avoid loading feedback rows.
+4. **`GET /api/v1/tenders/recommend`** — May involve recommendation/AI logic; profile separately from tender-approvals.
+
+### Suggested backend optimizations
+
+| Idea | Benefit |
+|------|---------|
+| Single aggregated `GET /api/v1/home` endpoint | One round-trip instead of 3 sequential |
+| Return stats + liked count alongside tender-approvals list | Eliminate calls 1 and 3 |
+| Slim tender DTO for list views (id, title, deadline, status only) | Smaller payloads on call #2 and #5 |
+| Cache stats and liked count with short TTL | Faster repeat visits / tab switches |
+
+### Suggested client optimizations (for reference)
+
+These are frontend changes the mobile team could make independently:
+
+- Run calls 1, 2, and 3 in parallel (`Future.wait`)
+- Do not re-run full `init()` on every tab switch — refresh only stale data
+- Await the recommend fallback before clearing loading state (avoids UI flicker)
+

+
+## Source files (client)
+
+| File | Role |
+|------|------|
+| `lib/view_models/home_view_model.dart` | Orchestrates all home API calls |
+| `lib/data/repositories/home_repository.dart` | Repository layer |
+| `lib/data/services/home_service.dart` | Stats, recommend, notifications |
+| `lib/data/services/your_tenders_service.dart` | Your tenders list |
+| `lib/data/services/liked_tenders_service.dart` | Liked count |
+| `lib/data/services/api/home_api.dart` | Endpoint path constants |
+| `lib/data/services/api/your_tenders_api.dart` | Tender-approvals URL builder |
+| `lib/data/services/api/liked_tenders_api.dart` | Feedback URL builder |
+| `lib/core/routes/app_shell/app_shell_screen.dart` | Background notification check |
+| `lib/views/home/pages/home_screen.dart` | Re-init on tab return |
+
+---
+
+## Quick test commands
+
+Replace `$TOKEN` with a valid access token.
+
+```bash
+# 1. Stats
+curl -s -w "\n%{http_code} %{time_total}s\n" \
+  'https://app.opplenz.com/api/v1/tender-approvals/stats' \
+  -H "Authorization: Bearer $TOKEN" | tail -1
+
+# 2. Your tenders
+curl -s -w "\n%{http_code} %{time_total}s\n" \
+  'https://app.opplenz.com/api/v1/tender-approvals?limit=10&offset=0' \
+  -H "Authorization: Bearer $TOKEN" | tail -1
+
+# 3. Liked count
+curl -s -w "\n%{http_code} %{time_total}s\n" \
+  'https://app.opplenz.com/api/v1/feedback?feedback_type=like&limit=1&offset=0' \
+  -H "Authorization: Bearer $TOKEN" | tail -1
+
+# 4. Notifications (background)
+curl -s -w "\n%{http_code} %{time_total}s\n" \
+  'https://app.opplenz.com/api/v1/notifications?seen=false&limit=1&event_type=PUSH' \
+  -H "Authorization: Bearer $TOKEN" | tail -1
+
+# 5. Recommended (only when your tenders empty)
+curl -s -w "\n%{http_code} %{time_total}s\n" \
+  'https://app.opplenz.com/api/v1/tenders/recommend?limit=10&offset=0' \
+  -H "Authorization: Bearer $TOKEN" | tail -1
+```
+
+Run all five and compare `time_total` to identify the slowest endpoint.
