Error rate reduction

Problem

Enterprise clients needed backend services that could handle growing data volumes without proportional infrastructure cost increases, while maintaining strict uptime and response-time SLAs.

Key Decisions

Quarkus over Spring Boot

Faster startup times and lower memory footprint in containerized environments, which is critical for elastic scaling under variable load and reducing cold-start penalty in Docker/K8s.

Layered architecture (resource → service → repository)

Kept test coverage tractable and made onboarding new engineers faster. Each layer has a single responsibility and can be tested in isolation.

Results

  • ✓25% improvement in data processing efficiency
  • ✓15% reduction in API response time
  • ✓95% service uptime maintained across production deployments
  • ✓30% reduction in error rates post-migration to structured exception handling
