Job Description

Project Overview

I have a mobile card game app built in Unity for iOS and Android that needs to be restored and made ready for submission to the app stores. The front end (C# in Unity) and back end (JavaScript) are mostly complete, but the database files have been lost. I am looking for an experienced Unity developer to:

Rebuild the backend and database.

Ensure the app is functional and ready for submission to the Apple App Store and Google Play Store.

Provide a quote for additional features (outlined below).

About the App

Blvcker is a multiplayer card game app that allows players to compete in various card-playing styles. Key features include:

Multiplayer Gameplay: Supports different card game styles.

Player Profiles: Users can add friends, track win/loss data, and maintain stats.

Messaging: Text-based chat with image-sharing capabilities.

Leaderboards: Displays rankings and achievements.

The immediate goal is to restore the database and ensure the current app is polished and published. After that, I plan to add new features such as in-game voice chat, live streaming, and an AI-assisted learning mode.

Project Details

Current Tech Stack

Front End: Unity (C#)

Back End: JavaScript

The app is largely complete, but the database must be rebuilt due to missing files.

Responsibilities

Code Assessment: Review the existing Unity front-end and JavaScript backend.

Database Reconstruction: Restore or rebuild the database to support player profiles, messaging, leaderboards, and gameplay.

Testing & Debugging: Ensure the app runs smoothly on both iOS and Android devices.

Additional Features (Quoted Separately)

After completing the core rebuild, I will need a separate quote for:

In-Game Voice Chat

Live Streaming & Text Chat (watch gameplay in real-time)

AI-Assisted Tutorial (teaching new users how to play the card game)

These features are not included in the initial $1,500 budget but will be estimated once the database rebuild is complete.

Skills & Qualifications

Unity (C#): Experience with mobile game development.

Backend Development (JavaScript): Ability to work with server-side code.

Database Design: Expertise in creating schemas and data structures for profiles, messaging, and leaderboards.

iOS & Android Deployment: Familiarity with submission processes for Apple and Google Play.

Version Control: Experience with Git or similar tools.

Bonus Skills: Knowledge of real-time communication features (voice chat, live streaming).

Budget & Timeline

Budget: $1,500 for rebuilding the backend and database, plus store submission.

Payment Terms: Open to milestone-based or project-based payments.

Timeline: Target completion within 4–6 weeks, including testing and submission.

Success Criteria

Functional Backend: Players can register, log in, and update profiles.

Stable Multiplayer: Card gameplay works smoothly across devices.

Messaging & Leaderboards: Fully operational within the app.

App Store Submission: Approved or close to approval by Apple and Google.

Feature Planning: High-level estimate for implementing additional features.
