Open source Java developer
working on Kubernetes
and OpenShift.

Focused on GitOps, automation, and AI

Software Developer at IBM
Focus: Kubernetes

I work mainly in open source, building and testing Java-based tooling around Kubernetes and OpenShift. Most of my public work happens through collaborative projects like StreamsHub, skodjob, Strimzi, and EnMasse, with a lot of focus on GitOps, automation, and platform reliability. Lately I have also been spending time on AI tooling and MCP, mainly from the Java side.

Built for production.

My work sits at the intersection of software development, operations, and quality. I care about systems that are understandable, testable, and stable when people actually have to run them.

Profile

I write software, build test tooling, and help shape the delivery side around it. A lot of my work has been in Kubernetes and OpenShift environments, especially around operator testing, CI/CD, and production-like validation. I tend to work where development, platform concerns, and release confidence meet.

How I add value

  • Reduce friction between development, testing, and operations.
  • Design workflows that make reliable releases easier, not slower.
  • Automate validation around Kubernetes platforms and operator-based systems.
  • Keep engineering quality visible through faster, more useful feedback loops.

2 Major chapters

Professional track shaped by Red Hat and continued today within IBM.

Certifications

Professional credibility built through hands-on Red Hat certification tracks, public technical work, and ongoing badge-based learning. Architecture, OpenShift platform design, and cloud-native platforms are core areas.

Red Hat certifications

I hold Red Hat certifications including Red Hat Certified Architect and Red Hat Certified OpenShift Architect. Those certifications align directly with the platform, architecture, Kubernetes, OpenShift, and production-oriented engineering work I do.

Current direction

AI and MCP

Current exploration is focused on AI-native engineering workflows, practical automation, and building with MCP.

Experience

Publicly visible experience shows a path through Red Hat into IBM, with long-running focus on reliability, operator testing, automation, and delivery quality in Kubernetes-centered environments.

IBM

Continuing work across software development, engineering quality, and operational effectiveness. The emphasis is on dependable delivery, strong feedback cycles, and engineering systems that remain healthy as they evolve.

Red Hat

Built experience in environments where Kubernetes, OpenShift, platform reliability, and practical automation matter. That background continues to shape how I approach release quality, operator testing, and engineering workflow design.

Projects

Most of my public code is collaborative open-source work rather than standalone personal repositories. The strongest examples sit across StreamsHub, skodjob, Strimzi, and EnMasse.

Collaborative project

kubetest4j

A library for testing Kubernetes deployments and operators using the Fabric8 API. It fits closely with the kind of cloud-native testing and validation work I spend most of my time on.
