Overview
Led the architecture and development of a comprehensive affiliate tracking platform for a major iGaming company. The system needed to handle millions of players, track complex referral chains, and calculate commissions with financial-grade accuracy.
The Challenge
Build a distributed tracking system handling millions of players and thousands of affiliates with financial-grade accuracy
- Legacy system couldn't scale beyond 1000 events/minute
- Manual commission calculations led to disputes and delays
- No real-time visibility into affiliate performance
- Data inconsistencies between tracking and payment systems
The Solution
01Distributed event ingestion pipeline
02Real-time processing architecture
03High-accuracy tracking system
04Scalable microservices design
Technical Approach
- Designed event-driven architecture using AWS Lambda and SQS for decoupled processing
- Implemented CQRS pattern to separate read and write workloads
- Built real-time dashboards using Hasura GraphQL subscriptions
- Created idempotent event handlers to ensure exactly-once processing
Key Decisions
Chose Serverless over Kubernetes
Why: Auto-scaling requirements and cost optimization for bursty traffic patterns
PostgreSQL with Hasura over custom GraphQL
Why: Rapid development with built-in subscriptions while maintaining flexibility
Event sourcing for financial transactions
Why: Complete audit trail and ability to replay events for reconciliation
Results
10x improvement in event processing capacity
Reduced commission calculation time from hours to real-time
99.9% accuracy in tracking attribution
Zero data loss during peak traffic periods
Lessons Learned
- 1.Event-driven architectures require robust dead-letter queue handling
- 2.Financial systems need idempotency at every layer
- 3.Real-time doesn't always mean instant - define acceptable latency
