Developer for Subscription-Based Sports Prediction Platform

Reference: https://sportybet.com/

We are building a subscription-driven sports prediction platform similar in concept to a legal, skill-based betting system.
Users will subscribe monthly and get one daily bet opportunity consisting of three game predictions (football, tennis, basketball, etc).

If all three predictions are correct, users earn points that contribute to daily and season leaderboards.
The platform integrates real-time odds and game data from external sports APIs (e.g., API-Sports, Sportradar, or OddsAPI).

Core Features & Requirements:

1- User System

Custom registration (name, DOB, username, email, password, bank info).

Monthly subscription system (Stripe / Paystack / PayPal).

Auto-renewal every 30 days with a countdown timer.

Email verification (phone optional).

2- Betting / Prediction Logic

Each user can place 1 bet per day consisting of 3 games in one slip.

Supports Football, Tennis, and Basketball (expandable to 5 sports).

Odds automatically fetched from external API and locked at bet time.

If any prediction fails, the entire bet is void (0 points).

Only matches starting on the current day can be selected.

3- Leaderboard System

Daily Leaderboard: Top 20 users with highest total odds (earlier timestamp wins in case of tie).

Season Leaderboard: Cumulative performance over time.

Leaderboards display username, odds, and timestamp.

Ability for users to click on other users’ profiles and chat.

4- Chat System

Real-time user-to-user messaging (WhatsApp-style).

Notifications for new messages.

5- Game Results & Odds

Fetched automatically from APIs (e.g., Sportradar, API-Football, SportsDataIO).

Admin fallback to manually enter or correct results.

6- Payouts

Automatic daily payout to users’ registered bank accounts (based on winning or leaderboard position).

7- Admin Dashboard

Real-time monitoring of system, users, and chats.

User management (CRUD, approvals, upgrades).

Manage sports data, leaderboards, and payouts.

Push notifications for opt-in users.

Analytics and performance metrics dashboard.
