We built a global event management application for organisations running conferences, summits, and multi-venue programmes across regions — a scalable platform combining Ruby on Rails for core event domain services, Angular for the operator and attendee experience, and FastAPI for high-throughput APIs, integrations, and real-time workloads.

Outcomes

Shipped a production platform for planning, publishing, and operating events across multiple countries and time zones.
Delivered self-service registration, ticketing workflows, session scheduling, and venue capacity management at global scale.
Enabled role-separated experiences for organisers, staff, vendors, and attendees with audit-friendly activity trails.
Architected for elasticity — FastAPI services handle peak registration bursts and integration traffic without blocking core Rails workflows.
Launched real-time dashboards for check-in status, session occupancy, and operational alerts during live event windows.
Integrated email notifications, calendar exports, payment collection, and third-party CRM/marketing connectors.

Challenge

The client operated large-format events worldwide and had outgrown spreadsheet-driven planning and fragmented tooling. They needed one system that could model complex programmes — multi-track agendas, speaker rosters, sponsor packages, and on-site logistics — while staying responsive during registration spikes and live event days. Different teams needed tailored UIs, but all data had to stay consistent across regions. Legacy monolith approaches could not meet throughput and integration demands without sacrificing maintainability.

Solution

Built the core event domain on Ruby on Rails — organisations, events, venues, sessions, registrations, roles, and billing with mature conventions for rapid feature delivery.
Developed the primary web application in Angular — modular feature areas for programme builders, registration portals, check-in consoles, and reporting with responsive layouts for field staff.
Introduced FastAPI microservices for performance-sensitive paths: bulk registration APIs, webhook ingestion, search indexing, analytics aggregation, and partner integrations.
Designed an API gateway pattern so Angular clients consume a unified surface while Rails and FastAPI services own clear bounded contexts.
Implemented queue-backed jobs for email delivery, PDF badge generation, data exports, and post-event reconciliation during traffic peaks.
Added observability across services — structured logging, health checks, and alerting tuned for pre-event and live-event operational windows.

Stack

Core platform — Ruby on Rails, PostgreSQL, Redis, background job workers, REST APIs.
Frontend — Angular, TypeScript, component-driven UI, role-based routing, i18n for multi-region audiences.
High-throughput services — FastAPI, Python, async endpoints, integration adapters, real-time feeds.
Infrastructure — Containerised deployment, horizontal scaling for registration peaks, CDN for static assets, secrets and environment separation per stage.
Integrations — Payment gateways, email providers, calendar feeds, CRM/webhook partners, SSO for enterprise organisers.
