Optional Enhancements

Caching Improvements

What Is Caching?

Imagine you have a popular recipe that you photocopy frequently. Instead of rewriting it each time, you keep copies ready. Caching is the same - keeping frequently accessed data ready so you don't have to re-fetch it from the database.

Current Situation:

✅ We have Redis (a fast caching system) but not all endpoints use it yet.

Enhancement Opportunities:

• Cache user profile data (user details don't change often)
• Cache pathway information (rarely updated)
• Cache language lists and settings
• Cache search results

Benefits:

• Faster response times (users don't wait)
• Lower database load
• Better performance during peak times

Timeline:

Easy wins, can be done incrementally - 1-2 weeks total

Push Notifications

What It Does:

Send alerts to user devices directly (like WhatsApp notifications) when something important happens.

Possible Uses:

• 📧 New message: "You have a new letter from your therapist"
• 📅 Appointment reminder: "Your appointment is tomorrow at 2 PM"
• 🎯 Goal update: "You've reached a milestone!"
• ⚠️ Important updates: "New features available"

Implementation:

• Requires Firebase or similar service
• Mobile app needs permission from user
• Backend sends notification requests

Timeline:

2-3 weeks if using Firebase (straightforward setup)

Email Notifications

What It Does:

Send emails when important events happen (login alerts, new messages, reminders).

Current Status:

⚙️ Mail system is configured but not heavily used yet.

Opportunities:

• Welcome email for new users
• Password reset emails
• Activity summaries (weekly digest)
• Important announcements

Benefits:

• Users stay informed
• Increases engagement
• Reduces support questions

Timeline:

Already mostly ready, just need queue setup - 1 week

Advanced Search Features

Current State:

Basic search exists but could be enhanced.

Improvements:

• Filter by multiple criteria (date range, type, status)
• Saved searches (users bookmark favorite searches)
• Search history
• Suggest similar searches

Timeline:

Phased over 3-4 weeks

Export Functionality

What Users Want:

Download their data in common formats (CSV, PDF, Excel).

Examples:

• Export diary entries as PDF or Word document
• Download activity history as CSV
• Generate progress report

Benefits:

• Users feel they own their data
• Useful for sharing with healthcare providers
• Data portability (legal requirement in some regions)

Timeline:

2-3 weeks implementation

Two-Factor Authentication (2FA)

What It Does:

Users enter password AND a code from their phone to login (extra security layer).

Implementation Options:

• SMS codes (text message with code)
• Authenticator apps (Google Authenticator, Authy)
• Email codes
• Biometric (fingerprint, face recognition)

Benefits:

• Protects against password theft
• Better compliance with security standards
• Users appreciate the security option

Timeline:

2-3 weeks (authenticator apps easiest)

API Rate Limiting Details

Current Status:

⚙️ Basic structure exists, could be enhanced.

Enhancements:

• Different limits for different endpoints
• Different limits for free vs premium users
• Graduated backoff (slowly reduce rate as limit approaches)

Timeline:

1-2 weeks
