Tiketfy
Full-Stack Developer
About the Project
Tiketfy is a live event ticketing platform, now running on the NestJS + Next.js architecture I migrated it to from a legacy Vite/Supabase stack. The platform handles event discovery and management, ticket sales with Paystack payment processing, background job queues, and WebSocket-based real-time notifications, with a separate organizer console alongside the public site. I rebuilt the stack with a focus on scalability and proper role-based access control.
Key Highlights
- Migrated the platform off a legacy Vite/Supabase stack onto NestJS + Next.js without downtime
- Built RBAC system with granular roles and permissions for event organizers
- Integrated Paystack for secure payment processing and ticket purchases
- Implemented real-time notifications via WebSocket (Socket.io)
- Atomic ticket counting with background job queues (BullMQ) to prevent overselling
Technical Challenges
Migrating a live platform to a completely new architecture while maintaining service continuity required careful parallel development. The atomic ticket counting system was critical — using database-level locks and a reservation queue to handle concurrent purchases without race conditions.
