// Open Source
Software
A selection of open-source tools and production-focused experiments.
// What I Do
Services
Technical expertise across infrastructure, engineering, and architecture.
Solution Architecture
Design of scalable technical systems with a focus on security, maintainability, and operational quality.
Software Engineering
Backend services, APIs, and full-stack applications with maintainable architecture and production focus.
DevOps & Infrastructure
Cloud-native infrastructure with Kubernetes, Terraform, CI/CD, monitoring, and automated delivery.
// Why
Built for outcomes, not slide decks.
Pragmatic architecture, reliable delivery, and engineering decisions that hold up in production.
Every engagement focuses on delivery quality, operational reliability, and measurable business impact. The goal is simple: to deliver architecture and implementation that remain easy to evolve, maintain, and scale long after launch, without slowing teams down as requirements grow.
01 Architecture First
Clear system design aligned with security, scale, and maintainability from day one.
02 Reliable Delivery
Transparent execution with measurable milestones and production readiness.
03 Long-Term Quality
Clean implementation, observability, and operational simplicity.

How I ended up implementing a cert-manager ACME DNS-01 solver webhook for All-Inkl.com
TL;DR: I wanted a TLS cert for an internal Keycloak, my DNS is at All-Inkl, no cert-manager webhook existed for them, so I wrote one: github.com/wenisch-tech/cert-manager-webhook-allinkl. This is the story of how a 20-minute job turned into a weekend Go project. It started with a redirect that wouldn’t redirect I was standing up a standalone Keycloak…

Meet Proxera: a self-hosted alternative to Cloudflare Tunnel
Proxera is a self-hosted reverse tunnel platform designed to expose private services without opening inbound ports, while keeping infrastructure ownership and routing control in the operator’s hands. It positions itself as an alternative to Cloudflare Tunnel by using the same outbound-connection model, but without depending on Cloudflare’s managed edge and account model. For teams running…

Validating Docker Image Pullability without the Docker cli or socket
When you’re running an uptime monitor, checking whether a container image is actually pullable is a surprisingly deep problem. The naive approach — spinning up a Docker daemon and running docker pull — is heavy, requires socket access, and introduces a serious security risk in most environments. Kairos solves this differently: by speaking directly to the OCI Distribution…
