New Professional Title Options: Option 1 (Super Tight): High-Security Earning App: Native Java (Android) & Laravel (Backend) Expert Required Option 2 (Full Professional): Full-Stack Developer for "Kamyabi Cash": Native Android App & Scalable Laravel Admin
Budget: $140 – $180 USD
Important Note for Bidders:
We previously initiated this project with another developer, but due to technical errors on their side, they were unable to complete it. We are now looking for a top-tier expert who can understand our existing logic and deliver a rock-solid system. Only serious experts should bid; further details will be discussed in private chat.
Project Overview:
I am building "Kamyabi Cash," a 100% Free Earning Platform. This project requires an expert who prioritizes high-level security and anti-fraud mechanisms. If you cannot handle complex security logic or are a slow developer, please do not apply.
1. Core Security & Anti-Fraud System (Critical):
Device Fingerprinting: Strictly One Account per Device. The system must use Device Fingerprinting and Android ID to uniquely identify hardware (avoiding restricted IMEI).
Zero Tolerance Policy: Instant and permanent ban for any user using Clones, Parallel Space, or Multiple Accounts.
Smart Verification: Integration of Firebase Phone/WhatsApp Authentication and Invisible reCAPTCHA/Cloudflare Turnstile to ensure only real users register.
VPN Detection: Automatic detection and blocking of users attempting to use VPNs or Proxies.
Referral Lock: Registration is impossible without a valid invitation code.
2. Daily Task Logic & Economy:
24-Hour Task Cycle: The "Task" button must only appear after the full 24-hour countdown from the previous cycle is complete.
3-Minute Cooldown: A mandatory 3-minute interval between each task to ensure quality ad engagement.
Task List:
Task 1 & 2 (Ad Watch): Earn 15 PKR per task after watching a full Google Ad.
Task 3 (The Invite Challenge): Invite exactly 15 verified friends. Reward: 80 PKR. The "Receive" button only appears when the 15th invite is verified. If even one is missing, reward is 0 PKR.
Task 4 (The Spin Wheel): Rewards of 15, 25, 50, and 199 PKR. Logic must favor 15 PKR and "Try Again" results.
3. Ad Integration & Revenue Safety:
Primary: Google AdMob.
Fallback Strategy: Integration of secondary SDKs (Unity, AppLovin, or AdColony) to ensure revenue continuity if the primary account is limited.
4. Multi-Level Referral & Salary System:
Structure: 6-Level tracking for Admin; 3-Level visibility for users.
Commission: Level 1 (10%), Level 2 (5%), Level 3 (2%).
Referral Reward: 3 PKR for every real, verified Level 1 invite.
Monthly Salary Tiers: Range from 200 invites (1,500 PKR) up to 2,500 invites (30,000 PKR) based on real user verification.
5. Technical Requirements:
Native Android App + Professional Landing Page.
Payment Gateways: EasyPaisa, JazzCash, and USDT (TRC-20).
Admin Panel: Comprehensive control over user management, blocking, and manual salary approvals.
Community: Links for TikTok, FB, YouTube, WhatsApp Community, and Telegram.
