Unity WebGL + AWS Deployment — Get a Browser-Based Casino Demo Live

We have a fully-built 3D browser-based casino platform (Unity WebGL frontend + Spring Boot backend) that has never been deployed. All the code and infrastructure-as-code (Terraform) exists and is well-documented, but nobody has ever run a build or stood up the AWS infrastructure. We need someone to take this from "source code" to "working link I can demo to prospects." This is NOT a from-scratch build — it's deployment, configuration, and debugging of existing, documented code. WHAT EXISTS ALREADY: - Unity project (Unity 2023.2.19f1, WebGL target) — 3D casino environment with player movement, login/auth flow, wallet/balance UI, and two embedded slot game scenes. Has a README documenting exactly which URLs/config values need to be set before building. - Backend API (Spring Boot, Java 17, Gradle, Dockerised) — handles auth, balance, deposits, guides. Has a README with exact Docker build → ECR push steps. - Infrastructure as code (Terraform) — defines the full AWS stack: VPC, security groups, RDS (two instances — auth + wallet), ECS Fargate services, ALB, CloudFront, S3, IAM. Includes a documented terraform.tfvars template and required IAM permissions. - AWS account with admin access will be provided. GitHub repos (3 separate repos) will be shared with you. WHAT'S NOT DONE (this is the actual gap): - Unity project has never been built into a final WebGL package. - Backend Docker image has never been built or pushed to ECR. - Terraform has never been applied — zero live infrastructure currently exists. - No domain is currently pointed at anything real. SCOPE OF WORK: 1. Build the Spring Boot app, build the Docker image, push to ECR. 2. Set up terraform.tfvars with secrets (can be freshly generated), run terraform apply, debug any first-deploy issues. 3. Update Unity project's hardcoded API URLs and auth config (Auth0, Google, Facebook), build for WebGL. 4. Deploy frontend via S3 +
