Order Orchestration Platform - Microservices Redesign

Led the architectural redesign of a complex order orchestration platform serving millions of transactions. Implemented Spring Boot microservices with Spring Cloud for service discovery, circuit breakers, and distributed tracing. Migrated from monolithic architecture to cloud-native microservices on AWS.

Key Achievements

30% reduction in system latency
40% decrease in technical debt
Zero-downtime deployments achieved
Team of 12+ engineers successfully led
Improved system reliability from 99.5% to 99.9%

Challenges

!
High latency in order processing (average 500ms+ response time)
!
Monolithic architecture causing deployment bottlenecks
!
Difficulty scaling individual components independently
!
Complex business logic tightly coupled across services
!
Need for zero-downtime deployments
!
Legacy system integration while maintaining backward compatibility
