01 / Architecture
Enterprise architecture focus
This portfolio presents architecture decisions and operational evidence from enterprise platforms: legacy-to-cloud integration, distributed processing and critical operations automation.
The cases connect Java · Spring Boot backends, Angular frontends, MuleSoft · Apache Kafka integration and AWS · Azure · GCP deployments. Each identifies role, scope, technical decision and operational status.
