Point Pickup: Microservices Transformation
From Monolith to Scalable Microservices Architecture
Industry:Last-Mile Delivery
Duration:18 months
Team Size:12 engineers
Client:Point Pickup Technologies
The Challenge
Point Pickup's monolithic architecture was struggling to handle rapid growth, with frequent outages, slow deployment cycles, and difficulty scaling individual components. The system was processing 100K+ deliveries daily but couldn't scale efficiently.
Key Pain Points
- ⚠️60+ minute incident response times
- ⚠️Weekly deployment cycles with high risk
- ⚠️Inability to scale components independently
- ⚠️Tight coupling causing cascading failures
- ⚠️Developer productivity bottlenecks
The Solution
Architected and led the migration to event-driven microservices using Domain-Driven Design principles, implementing zero-trust security and automated deployment pipelines.
Solution Approach
- ✅Strangler Fig pattern for gradual migration
- ✅Event-driven architecture with Apache Kafka
- ✅Zero-trust security with service mesh
- ✅Automated CI/CD with blue-green deployments
- ✅Comprehensive monitoring and observability
