Workverse Simulation Platform

A product company needed a complete backend for a training game: assessments, scoring, rewards, analytics, certificates and trustworthy sign-in on mobile devices, plus a dashboard for the organisations running it.

• Architected the full backend on Node.js, Express.js and MongoDB.
• Built assessments, a scoring engine, badge rewards, analytics tracking and automated certificate generation.
• Implemented Firebase Auth, Google OAuth2 and Apple token verification with device-level identity rules.
• Deployed and scaled on AWS; containerised services; set up Nginx and CI/CD.

1. 01

   Game clients

   Mobile clients authenticate through Firebase, Google OAuth2 and Apple token verification.

2. 02

   API services

   Node.js and Express services, containerised with Docker behind Nginx.

3. 03

   Data & storage

   MongoDB for game and assessment data; S3 for assets and generated certificates.

4. 04

   Async work

   SQS, Lambda and SES for background jobs and email, monitored through CloudWatch.

5. 05

   Admin dashboard

   A Next.js dashboard lets organisations manage learners and licences.

• Verify identity on the server for every platform, not just on the client.
• Move slow or retry-prone work (certificates, email) to queues instead of the request path.

• Enforcing identity rules per device without making sign-in painful.
• Keeping scoring consistent and auditable as assessment types grew.

• Backend platform, authentication, scoring and certificate generation.
• Admin dashboard for organisations (dashboard.workverse.in).
• AWS deployment with Docker, Nginx and GitHub Actions CI/CD.
