01 · The problem
v2 endpoints needed measurable improvements in latency and reliability while coordinating multi-service business logic consumed by dependent teams.
Internal crew management APIs supporting complex business rules across Node.js and Spring Boot services, modernized for latency and maintainability.
02 · My role
Technical Lead · API modernization (Myridius / Disney)
03 · The result
Migrated and improved v2 endpoints, coordinated business logic across Node.js and Spring Boot, and aligned with enterprise patterns used by API consumers.
04 · Architecture
- 01
Multi-service API surface spanning Node.js and Spring Boot
- 02
v2 endpoint modernization with clearer contracts
- 03
Enterprise patterns for dependent consumer teams
Implementation
- Improved v2 crew management endpoints
- Cross-service business rule coordination
- Enterprise-aligned API patterns for consumers
Challenges & outcomes
Challenges
- Improving latency without breaking dependent consumers
- Coordinating logic across heterogeneous service stacks
Outcomes
- Measurable latency and reliability gains on modernized endpoints
Lessons
- API modernization is as much about consumer contracts as raw speed
- Heterogeneous stacks need explicit ownership of business rules
