Projekthistorie
Architected and migrated a mission-critical infrastructure from DCOS/Mesos to a Kubernetes cluster, integrating Kafka, Zookeeper, API-Gateway, Elasticsearch, NiFi, Graph, Neo4j microservices, MongoDB, PostgreSQL, and Oracle23, achieving 95% availability.
Designed high-availability Oracle architectures using DataGuard + GoldenGate with primary and standby databases, delivering 99% uptime with automated failover.
Led a large-scale migration from Oracle to MongoDB with zero data loss and full transactional consistency across enterprise systems.
Implemented end-to-end CI/CD pipelines with GitLab CI (build, test, SonarQube coverage, deployment), eliminating 50+ repetitive manual tasks and accelerating delivery cycles by 40%.
Deployed proactive monitoring with Zabbix and Grafana, reducing incident response time by 80% and enabling predictive alerting.
Automated backup strategies for 100+ GitLab repositories, Oracle databases, and PostgreSQL instances, guaranteeing 99% backup reliability.
Built N8N automation workflows to calculate 100% of developer productivity metrics, visualized in Grafana dashboards for engineering leadership
- Led the complete virtualization transformation from physical to virtual infrastructure using VMware vSphere and Proxmox, reducing operational costs by over 50% and enabling the deployment of 35+ new public services.
- Managed and maintained 35+ Linux servers with full automation using Ansible and custom Bash/Python scripts, achieving 99.9% configuration consistency.
- Provided Level 2 and 3 technical support for internal and external stakeholders, resolving complex infrastructure incidents within SLA targets.
