Project Summary: I am developing Kamyabi Cash, a completely free earning platform. This project requires a developer who treats security and fraud prevention as top priorities. If you struggle with advanced security systems or cannot deliver efficiently, this project will not be a good fit. 1. Security & Anti-Fraud Framework (Top Priority) Device Identification: Only one account per device is allowed. The system must rely on device fingerprinting combined with Android ID to uniquely recognize hardware, without using restricted identifiers like IMEI. Strict Enforcement: Any user detected using cloned apps, parallel environments, or multiple accounts must be banned instantly and permanently. User Verification: Integrate phone authentication via Firebase and WhatsApp, along with invisible bot protection such as reCAPTCHA or Cloudflare Turnstile, ensuring only genuine users can sign up. VPN & Proxy Blocking: Automatically detect and prevent access from VPN or proxy connections. Invite-Only Access: New accounts can only be created using a valid referral code. 2. Task Cycle & Reward Mechanics 24-Hour Task Reset: The task button should only reappear after a full 24-hour countdown from the previous completion. 3-Minute Delay Between Tasks: Each task must include a mandatory three-minute pause to promote genuine ad interaction. Task Breakdown: * Task 1 & 2 – Watch Ads: Users earn 15 PKR per task after fully viewing a Google advertisement. * Task 3 – Invite Requirement: Users must invite exactly 15 verified friends to unlock an 80 PKR reward. The claim button appears only after the 15th verified invite; if even one is missing, the reward remains zero. * Task 4 – Spin Wheel: Possible rewards: 15, 25, 50, or 199 PKR. The probability must heavily favor the lowest reward and “Try Again” outcomes. 3. Advertising Setup & Revenue Protection Main Network: Use Google AdMob as the primary ad provider. Backup Strategy: Add secondary ad SDKs such as Unity, AppLovin, or AdColony to maintain monetization if the main account is restricted. 4. Referral Structure & Income System Hierarchy: Admin should track six referral levels, while users can view up to three. Commission Rates: * Level 1: 10% * Level 2: 5% * Level 3: 2% Direct Referral Bonus: Users earn 3 PKR for each real and verified Level-1 referral. Monthly Salary Milestones: Verification-based rewards starting from 200 invites (1,500 PKR) up to 2,500 invites (30,000 PKR). 5. Technical Scope * Native Android application plus a professional landing page * Payment integrations: EasyPaisa, JazzCash, and Tether (USDT TRC-20) * Admin dashboard with full user control, blocking tools, and manual salary approval features * Community links for TikTok, Facebook, YouTube, WhatsApp groups, and Telegram

Hey there, I see you're building Kamyabi Cash as a truly secure and fraud-proof earning platform , your emphasis on advanced security and seamless task flow tells me this project demands precision and rigor, exactly where I excel. With extensive experience in PHP, Laravel, Android app development (Java/Kotlin), and API integrations, I've successfully implemented robust device fingerprinting and multi-factor user authentication systems before. I will ensure single-account-per-device enforcement by combining fingerprinting with Android ID, integrate Firebase and WhatsApp for phone verification, and embed invisible bot defenses like reCAPTCHA or Cloudflare Turnstile. To block VPNs/proxies, I'll leverage proven third-party services and configure strict referral validations. For rewards, I can script the 24-hour reset, enforce task delays, implement weighted spin wheel probabilities, and integrate Google AdMob plus secondary ad SDKs like Unity for reliable revenue streams. Your multi-level referral tracking and milestone-based salary feature will be crafted with intuitive admin controls and secure payment gateways (EasyPaisa, JazzCash, USDT TRC-20). I've shared an initial estimate based on your description, and once we go over a few technical or functional details, I'll confirm the exact cost and delivery schedule. Let’s start by refining your user security framework and task flow. How do you currently plan to manage device fingerprinting to ensure compliance with Android's ident

As a seasoned web and app developer, I have the perfect fit of skills and knowledge to bring your Kamyabi Cash project to life. From performing device identification using Android ID and device fingerprinting techniques to blocking VPN and proxy connections for added security, I have got what it takes to prioritize security and anti-fraud framework as you desire. Over the years, I've worked on numerous task cycle and reward mechanics projects; ensuring that each task is implemented effectively by encompassing all your requirements. From setting up a 24-hour countdown before reappearance of the task button to incorporating a three-minute pause between tasks for authentic ad interaction, I'll ensure your platform functions optimally. With my experience in payment integration, I am confident in my ability to integrate EasyPaisa, JazzCash, and Tether (USDT TRC-20) into the system. In addition, my experience working with Google AdMob as a primary ad provider gives me an edge in carrying out an effective advertising setup while ensuring revenue protection by adding secondary ad SDKs like Unity or AppLovin. I understand the importance of revenue generation in such platforms and will employ this understanding throughout the project.

Hello!!! I HAVE ALREADY WORKED ON SIMILAR TYPE OF PROJECT, OPEN CHAT WINDOW I WILL SHARE MY WORK. I have two questions: Do you want the 24-hour task reset and 3-minute delay logic handled entirely on the server side to prevent manipulation? And should the referral verification be automatic via OTP or manually approved by the admin? What I offer: ⭐ Native Android app development with high security and anti-fraud measures ⭐ Device fingerprinting, VPN/proxy blocking, and single-account enforcement ⭐ Firebase & WhatsApp verification with invisible bot protection ⭐ Task cycle logic with timers, ad integration, and reward mechanics ⭐ Multi-level referral tracking and commission system with dashboard controls ⭐ Payment integrations (EasyPaisa, JazzCash, USDT TRC-20) and admin panel I have 7+ years of experience in secure mobile apps, reward systems, and backend integrations. My approach: I will first set up the security and verification framework, then implement task and reward logic, followed by ad monetization and referral tracking. Finally, I will test thoroughly to ensure integrity and smooth performance. Let’s discuss in chat so I can share examples and finalize the plan. Best Regards, Shaiwan Sheikh

Hi there This type of earning platform lives or dies on security, fraud control, and stable monetisation — so the architecture has to be designed around abuse prevention from day one. I’ve worked on SaaS, fintech-style systems, and ad-driven platforms where anti-fraud, referral logic, and secure payouts were critical. **How I’d approach it:** • Device fingerprinting + Android ID hybrid identification with clone/app-parallel detection • Firebase phone auth + bot protection (reCAPTCHA/Turnstile) + VPN/proxy filtering • Strict referral validation logic with multi-level commission tracking • AdMob primary monetisation with fallback ad network integration • Secure payment flows for EasyPaisa, JazzCash, and USDT TRC-20 • Admin dashboard for user control, approvals, and fraud monitoring **Deliverables:** • Native Android app with secure earning workflow • Landing website aligned with the app branding • Full admin panel with fraud controls and reporting • Referral/reward system implemented as specified • Clean, maintainable code with deployment guidance If security, scalability, and long-term stability are the priority, I’d be glad to discuss the architecture and next steps.

Hi there, I am a strong fit for this scope because I have built reward-based Android platforms where fraud control, device restrictions, and revenue protection were core requirements from day one. I have implemented device fingerprinting with Android ID validation, Firebase phone authentication, referral hierarchies, timed task engines, wallet systems, and controlled payout flows with admin approval layers. I work with native Android in Kotlin, Firebase, secure REST APIs, server-side fraud detection logic, AdMob with fallback SDK mediation, and payment integrations including EasyPaisa, JazzCash, and USDT TRC-20. I reduce risk by enforcing server-side validation for every reward trigger, isolating anti-fraud logic from client code, logging suspicious behavior for audit review, and structuring monetization to avoid ad policy violations. I am available to start immediately and can begin with a clear technical architecture plan before development. Regards Chirag
