Project Snapshot

Large-scale ticketing requires more than a monolith. This platform delivers fault-tolerant ticket sales through a suite of focused services, synchronized via NATS JetStream and packaged for Kubernetes deployments.

Business Context

  • Designed as a blueprint for marketplaces that need resilient shopping and payment flows.
  • Demonstrates battle-tested event patterns, ready to extend into high-availability production environments.
  • Enables rapid onboarding of frontend teams thanks to a modern Next.js client already wired to the APIs.

Core Capabilities

  • Microservice topology covering authentication, ticket inventory, orders, payments, and expirations.
  • JetStream event bus embedded in the app for at-least-once delivery without extra infrastructure overhead.
  • JWT-secured access with HTTP-only cookies and shared validation packages in common/.
  • Responsive frontend built in Next.js + Tailwind CSS, delivering a premium checkout experience.
  • Automated expirations that release tickets back to inventory when shoppers abandon carts.

Architecture Highlights

  • Dockerized services orchestrated via Kubernetes, with Skaffold scripts to streamline local dev loops.
  • MongoDB stores transactional data while Redis can back transient caching or event replays.
  • Shared TypeScript packages ensure consistent events, models, and error handling across services.
  • Jest and Supertest guard critical workflows through unit and integration coverage.

Implementation Notes

  • Prioritizes observable, maintainable code: modular structure, dedicated namespaces, and defensive middleware.
  • Real-time messaging flows documented for teammates stepping into the platform or extending integrations.
  • MIT-licensed foundations that welcome customization for corporate environments or startups alike.

My Role

I architected the distributed system, implemented the service contracts, and hardened the DevOps tooling so teams can iterate quickly without compromising reliability.
