WordPress Kundali Plugin Stabilization & Export

I have an existing kundali system built using multiple WPCode snippets. It is partially working but not stable.

I need FULL CONVERSION into ONE CLEAN CUSTOM PLUGIN with complete stability and future scalability.

========================
CORE REQUIREMENT
========================
- Convert all existing WPCode snippets (10+) into ONE custom plugin
- No dependency on WPCode after completion
- Modular architecture (each function independent)
- If one module fails, system should NOT break

========================
CORE FIXES
========================
- Fix blank screen / crash after API call
- Proper error handling (no raw echo)
- Structured response handling
- Logging system (store errors + API responses)

========================
API + CACHE SYSTEM
========================
- Use Prokerala API (already integrated)
- Implement caching based on:
DOB + TOB + POB
- Same input should NOT call API again
- Only ONE API call per unique data
- Store API response JSON in DB
- If API fails:
→ show cached result OR proper error message

========================
TESTING (IMPORTANT)
========================
- My API credits are exhausted
- You must develop using:
→ mock API response OR stored JSON
- System must work WITHOUT live API during development
- After completion:
→ We will test with real API

========================
SECURITY
========================
- Move API keys to secure config
- Validate all inputs
- Add rate limiting using:
→ mobile
→ email
→ IP

========================
LIMIT SYSTEM
========================
- Free limit = 5 per user
- Admin unlimited
- After limit → block + upgrade message

========================
DATA STORAGE
========================
- Store all client data
- Store API response JSON

========================
EXCEL EXPORT
========================
- Export CSV/Excel
- Filters:
→ Date-wise
→ Mobile-wise
→ Full export

========================
PERFORMANCE
========================
- AJAX-based system
- Loading indicator + retry

========================
STABILITY
========================
- No plugin conflicts
- Multiple testing should not break system

========================
FUTURE READY
========================
- Plugin must support:
→ Payment integration
→ Wallet system
→ Paid kundali
- Clean modular structure required

========================
FINAL DELIVERY
========================
- Clean plugin
- Fully working stable system
- No WPCode dependency

========================
SUPPORT
========================
- 7 days support after delivery
