Kojo Ampia-Addison
@kojoampia-addison
I build secure cloud-native Java platforms, modernize critical systems, and lead DevOps, monitoring, and architecture delivery.
What I'm looking for
I've migrated, refactored, and improved core finance APIs at Bundesrechenzentrum (BRZ), supporting access management, client changes, and operations with metrics, traces, logs, and GitOps-based deployments.
For Abofonsa Mobile Health Service and Bedrock Insurance Ghana, I led architecture and delivery of role-based dashboards, public web platforms, and near-real-time communication services using Java, Spring Boot, JHipster, Angular, Kafka, MongoDB, Prometheus, and Grafana.
I've delivered DevOps and observability work for Accenture, Austrian Railways (ÖBB), and Swiss Railways (SBB), including OpenShift migrations, SLI/SLO metrics, CI/CD pipelines, operational dashboards, and tooling to improve stability.
My background spans secure software, cloud platforms, microservices, database engineering, web engineering, telecommunications billing, and technical leadership. I lead architecture, quality, stability, and project delivery while mentoring junior developers.
