@iosifpeterfi

I'm Iosif Peterfi, 15+ years helping brands ship impactful web and mobile experiences. This is my speciality: turning multi-brand game concepts into a single, polished mobile experience with secure sign-in, reliable payments, fair leaderboards, and admin-ready controls that protect prizes. You need a Unity mobile game for iOS and Android with two branded modes (general trivia and sports trivia) plus a jigsaw puzzle, plus backend API, database, and admin panel. I will deliver a unified project for both brands, with brand switching, a backend and database, and an admin panel to manage winners, weekly puzzles, and fraud alerts - all documented for updates. A similar project for a regional trivia brand shifted from manual prize checks to automated verification, cutting disputes and support time by over 40%. Daily top players and weekly puzzles boosted engagement by 25%. Happy to discuss scope alignment. Let's chat - I can walk you through my approach in 15 minutes.

I pride myself on my intense attention-to-detail while integrating REST APIs, including payment gateways and leaderboards, ensuring seamless operations. Additionally, I have a wealth of expertise in database design using MySQL and PostgreSQL and building admin panels. My estimated timeline for this project is flexible based on the complexity of your specific requirements. However, you can rest assured that I will prioritize quality in my work while delivering timely solutions within any parameters or budget set forth. Let's connect so we can discuss your project needs further!

@slavkom1

Hi there. Your quiz, sports trivia, and weekly puzzle app is clear, and I can take it on in a direct way. I’ve shipped several Unity mobile games using C#, custom APIs, Entra-style auth, and payment flows, so the mix here is familiar. I’d build it step by step: - Set up both trivia modes and the puzzle mode inside one Unity project with brand switching - Build clean REST APIs for payments, leaderboards, and game data - Set up the database design for daily and weekly resets - Build the admin panel for uploads, winner checks, and anti-fraud logs - Handle Entra ID, device checks, and deploy to your Hostinger VPS I can start right away and expect around three weeks for a full first version. Do you want leaderboard timing stored in raw milliseconds from the device or normalized on the server for stricter anti-fraud control? Thanks, Slavko

Hello, there! I’m a senior Unity developer with strong experience delivering full-cycle mobile game systems, including backend APIs, payments, and secure competition logic. I’ve also developed the Swappies game, which involved interactive gameplay systems, real-time state handling, and polished UI/UX—directly relevant to your quiz and puzzle mechanics. I’ve built Unity mobile games (iOS/Android) using C#, integrated REST APIs for payments and leaderboards, and developed scalable backends with FastAPI/Node.js and PostgreSQL. I have experience implementing authentication flows (including Azure-based systems), as well as anti-fraud measures such as device fingerprinting, IP tracking, and session logging. For your app, I would design a unified Unity project with brand-based switching for CGN and QOS while maintaining a clean, maintainable architecture. The backend will handle millisecond-precision leaderboards, daily/weekly resets, and secure winner validation. The admin panel will allow full control over content, verification, and fraud monitoring. I focus on delivering stable, secure, and production-ready systems with clear communication throughout development. Best regards, Ian Brown

@adisonw

Dear Sir, I am thrilled to bid your project. This is a full product build, not just a game, and I understand the importance of combining stable Unity gameplay with a secure backend, payments, and fraud protection for real-money competitions. I have experience working with Unity mobile apps, REST APIs, payment integrations, and admin dashboards, and I focus on building systems that are reliable, scalable, and easy to manage after launch. For your project, I would structure it with a clean Unity app supporting both brands via theme switching, integrated with a backend API for authentication, leaderboards, payments, and fraud tracking. I can implement daily and weekly leaderboard resets, millisecond-level timing for fair ranking, and admin verification workflows for winners including ID checks and audit logs. On the backend, I would design a secure API with database structure for sessions, scores, payments, and anti-fraud signals such as device fingerprinting and IP tracking. The admin panel will allow you to manage winners, upload puzzles, review flags, and control core content without technical effort. I will also ensure proper deployment on your VPS and provide full documentation for maintenance. One key question I’d like to confirm first is this: for the anti-fraud system, do you want strict blocking rules (auto-disqualify suspicious users) or a flag-and-review approach handled through the admin panel? Sincerely, Adison.

@carlosd178

Hello, I’d be glad to help build your project by delivering a complete Unity-based quiz and puzzle app with a secure backend and admin system. I’m a full-stack developer experienced in **Unity (C#), mobile app development (iOS/Android), REST API integration, PostgreSQL/MySQL, payment gateway integration, and admin panel development**, with a strong focus on performance and reliability. One of the key challenges in projects like this is ensuring **real-time leaderboard accuracy, secure payment handling, and anti-fraud mechanisms while keeping gameplay smooth across devices**. My approach is to structure the Unity app with modular game modes, build a secure backend API for user, payment, and leaderboard logic. A couple of quick answers: • Examples: I’ve worked on Unity-based mobile apps with leaderboard systems, timed challenges, and API-driven gameplay (can share links privately due to client NDA). • Payment integration: experience with REST-based gateways, handling secure transactions, callbacks, and server-side validation. • Leaderboard & anti-fraud: server-authoritative scoring, timestamp validation, device fingerprinting, IP/session tracking, and admin verification flows. • Timeline & estimate: 5–7 weeks for MVP delivery, with a fixed budget proposal after reviewing full specs (or hourly if preferred). I’m interested in a long-term collaboration and help scale your projects reliably. Best regards, Carlos

As an enthusiastic Unity Game Developer with extensive experience and technical expertise, I believe I'm the perfect fit for your Unity mobile quiz and puzzle game project. I’ve already created a series of mobile games that are live on both the App Store and Google Play Store, including a 2D Shape Shifting Puzzle Game that shares similar mechanics with your puzzle game mode. Having done REST API integrations, payment gateway implementations, MySQL/PostgreSQL database design as well as developed admin panels throughout my career, I am confident in delivering every aspect of your anticipated app with remarkable proficiency. Though I'm relatively new here on Freelancer platform, my track record outside is impeccable. Let's start by building trust together through a small test project or create an initial milestone so we can both familiarize ourselves with the work environment. So let’s stop waiting - together let's build something awesome

@cindyviorinar

Hello Client, I’ve read your brief carefully and am confident I can deliver a secure, polished Unity mobile app combining CGN (general trivia), QOS (sports trivia) and the weekly jigsaw puzzle mode. I have extensive Unity (C#) mobile experience, REST API integration, payment gateway work and backend + admin panels. I will build a single Unity project with theme switching, integrate Microsoft Entra ID for auth and SMS verification, connect EpinLimited for payments, implement leaderboards with daily/weekly resets, and add device fingerprinting, IP tracking and session logging for anti-fraud. Backend (Node.js or PHP) + PostgreSQL, hosted and deployed to your Hostinger VPS, plus an admin panel to verify winners, upload weekly puzzle images, and review fraud flags. I’ll provide iOS and Android builds, documentation, and a staged deployment plan. I can start within 5 business days and aim to deliver an MVP in ~30 days with iterative releases and testing. Which prize payout and verification workflow should the admin follow when multiple fast perfect-game submissions arrive within the same millisecond window? Sincerely, Cindy Viorina
