B.Sc. Bioinformatics

Computer Science graduate running a homelab on Proxmox and learning DevOps by building things myself. Most of my projects are self-hosted on Gitea because I prefer keeping control over my infrastructure and data.

Currently looking for opportunities in DevOps, Platform Engineering, or Site Reliability - open to Backend roles as well.

Built a complete Kubernetes infrastructure on Proxmox with automated deployments:

• 3-node K3s cluster with high-availability setup
• Private Docker registry and self-hosted GitHub Actions runner
• ArgoCD handling GitOps - code push to deployment in ~5 minutes
• Prometheus + Grafana for monitoring with custom application metrics
• Zero-downtime deployments using rolling updates

Main challenges: Debugging ServiceMonitor configurations to get Prometheus scraping working, preventing infinite CI/CD loops, and getting anti-affinity scheduling right.

Stack: Kubernetes (K3s), ArgoCD, GitHub Actions, Docker, Prometheus, Grafana, FastAPI

Bachelor thesis project - built a neural network framework in Python and Rust without using ML libraries (only NumPy/ndarray for math). Implemented everything from backpropagation to training loops to compare performance between the two languages.

Running various services on Proxmox: Nextcloud for files, TrueNAS for storage with automated backups, PostgreSQL databases, and InfluxDB + Grafana for metrics. Learned the importance of backups the hard way after a server crash.

Most of my work lives on my private Gitea instance, so my GitHub activity doesn't show the full picture.

Expanding beyond GitOps into other DevOps areas - service mesh, Infrastructure as Code with Terraform, centralized logging, and better monitoring/alerting setups.

I prefer building things myself instead of just following tutorials. Takes longer sometimes, but I understand how everything actually works. Self-hosting is important to me - I like having full control over my infrastructure and data.
