About
Alper Arinç — DevOps Engineer
Profile
I have 10 years of DevOps and infrastructure experience, focused on Linux systems and automation. I currently run the DevOps processes of a multi-product software family in the fintech sector. My work covers operational automation with Python and Bash, CI/CD pipeline design on Jenkins and GitHub Actions, containerized architecture with Docker / Kubernetes (RKE2) / Helm, in-pipeline security and quality gates with Trivy and SonarQube, and Prometheus / Grafana based observability. I built the DevOps practice from scratch in an enterprise environment.
Before that, for 3+ years I was the sole person responsible for 24/7 critical systems in a hospital, keeping operations running without interruption; my calm, results-oriented approach during critical incidents comes from there. The entire infrastructure stack I work with is open source.
Now
- WildFly 36 production base image — CVE remediation on UBI 9, Trivy scans, Nexus & Harbor dual-push
- RandevuGo microservice architecture on a Hetzner RKE2 cluster
- Local AI Lab — Ollama, pgvector RAG and CrewAI multi-agent experiments on a Mac Mini M4
- InfraMemory — enterprise incident knowledge base built on pgvector + Ollama
- Jenkins shared library — dynamic tag/branch selection via the Gitea API, SonarQube + Trivy integration
