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. ...
