Real-time Multiplayer Educational Quiz App for Medical Students

We are seeking an experienced mobile app development team or freelancer to create Revaliday, a real-time, multiplayer educational quiz and academic competition platform. This application is specifically designed for medical students across South America, with a primary focus on preparing candidates for medical certification exams, such as the Brazilian "Revalida," through gamified, highly competitive, and interactive clinical simulations. The goal is to deliver a robust and engaging platform that enhances learning and exam preparation.

Core Gameplay & Mechanics:

User Profiles: The app will feature user profiles where players can enter a unique nickname and select their medical specialty (e.g., Clinical Medicine, Cardiology, Surgery). This information will be used for matchmaking and displaying in-game.

Matchmaking Arena: A sophisticated matchmaking system is required. When a user selects "Play" or attempts to join a specific room, the system must initiate a real-time matchmaking process. A critical feature is the seamless integration of highly realistic AI-driven "medical bots" (e.g., Dr. Ramos - Cardiology or Dra. Beatriz - Pediatrics) to fill lobbies if human players are unavailable. These bots need distinct visual identifiers (colors/avatars) and varying difficulty levels to ensure a challenging experience.

Round-Based Matches: Each competition will consist of dynamic rounds, typically featuring 3 clinical questions per round. Questions must be presented simultaneously to all participating players in the room.

Real-Time Interaction: Players will submit their answers within a strict time limit. The user interface must clearly indicate which players have submitted their answers (without revealing their choices) to build suspense and maintain engagement throughout the round.

Live Chat: An integrated, secure live chat room is essential for players and AI bots to interact during the match, fostering a competitive and social environment.

Instant Feedback & Scoring: Immediately after all players have submitted their answers or the time limit expires, the correct answer will be revealed. Player scores (acertos) must be updated and displayed in real-time, providing immediate feedback on performance.

We are looking for a solution that is scalable, secure, and provides an excellent user experience.
