Project examples

Technical insight from platforms, DevOps, and implementation.

Three real excerpts from my work: Kubernetes platforms, SaaS product development, and on-prem AI infrastructure with operations, observability, and handover.

Projects

Three real-world projects.

Three different starting points, with the same focus: clarify the architecture, structure the implementation, and plan for operations.

01 Kubernetes platform for production operations A cloud Kubernetes platform was built as an automated, highly available foundation for custom software. Open details
Starting point
Custom applications needed a reliable Kubernetes foundation in the cloud, including infrastructure, deployment foundations, supporting services, and clear operating processes.
My contribution
Built the Kubernetes platform with Terraform, established Argo CD as the GitOps foundation, and integrated core platform services such as deployments, secrets, CI/CD connectivity, and the Grafana stack into operations.
Outcome
Highly available platform with backup processes, CI/CD automation, Grafana/Loki/Prometheus observability, documentation, clear workflows, and knowledge transfer.

Technologies and topics

  • Kubernetes
  • Docker
  • Terraform
  • Argo CD
  • Helm
  • CI/CD
  • Postgres
  • GitHub
  • Grafana
  • Loki
  • Prometheus
02 Technical support for a new venture A SaaS app for Android and iOS was built from product planning through cloud operations. Open details
Starting point
A new SaaS app needed Android and iOS clients, a backend, an admin interface, and cloud operations from product idea through technical implementation.
My contribution
Implemented the Flutter app, built the backend with Python and FastAPI, added the React admin app, and integrated observability with Grafana, Loki, and Prometheus.
Outcome
Cloud deployment with Terraform and GitHub CI/CD, creating a clear technical foundation for product development, operations, and future SaaS growth.

Technologies and topics

  • Flutter
  • Docker
  • FastAPI
  • Python
  • React
  • Postgres
  • Grafana
  • Loki
  • Prometheus
  • AWS
  • Terraform
  • GitHub
03 AI team platform for technical workflows An on-prem AI platform was built on a k3s cluster for internal technical workflows. Open details
Starting point
AI services needed to run on-prem on a Proxmox cluster - highly available, secured, and fully manageable by the team.
My contribution
Built the k3s cluster with Terraform and Ansible, set up Bitbucket CI/CD and Argo CD GitOps, integrated Keycloak/OIDC, and deployed Open WebUI, LiteLLM, Langfuse, MLflow, MCP servers, and AI agent services.
Outcome
Fully documented platform with secret management, authentication, backup/restore, plus Grafana stack, alerting, on-call integration, and Grafana MCP for incident response.

Common patterns

What these projects have in common.

Different products, similar technical requirements: infrastructure as code, automated deployments, observable operations, and clean team handover.

  • Infrastructure as code instead of manual setup
  • CI/CD and GitOps as the operating foundation
  • Observability, alerting, and backups from the start
  • Documentation and knowledge transfer for self-managed operations
