• As Lead Cloud Architect, I ensure cost efficiency: Instead of paying €1 to Google Cloud Platform (GCP), I make sure our actual pay is ~60 cents

• I designed and built two Enterprise-grade GCP "tenants" incl. their foundational setup as well as the operational processes and guardrails

• I built the core GCP team and helped to grow it to 6 FTEs, including the hiring of 3 cloud architects and engineers

• I helped to adopt GCP from 0 to > €4M p.a., saving ~50% compared to on-premises

• I was directly involved in the implementation of several GCP discount agreements, e.g., with ~€270K additional saving in 2023 and ~€350K in 2024

• I helped to increase our overall 2024 production output by 2% (~€50M)

• I'm the sole developer of cecli, the missing gcloud browsers command

• As Architect, Common Build Services, I reduced CI capacity by ~20%, keeping the quantity to ~800 nightly builds and thousands of builds per day

• I help to introduce Enterprise-grade Kubernetes "the hard way", individually contributing to cluster- and application-level Observability

• As Development Manager for Oracle BPA Suite, I achieved ~140% ROI in 3 years

• I built up an office and a development outpost for 5 FTEs abroad, in the US

• As Team Manager Web Development, I saved a 7 digit figure deal from customer drop-out

• I mentored a thesis

• During my first 6 weeks, I developed a working prototype of a web-based search system, which was demoed at the world's largest IT trade fair, CeBIT

I served as a volunteer firefighter for over 30 years, starting as a junior cadet and eventually becoming a state-certified incident commander and group leader. During my tenure, I participated in over 100 firefighting operations, contributing to the safety and well-being of the community. Additionally, I created and developed the organization's website, enhancing communication and outreach efforts.

• Software Design and Implementation Using C++

"Diplom-Informatiker (FH)"

A location- and time-based reminder app for Android and iOS.

• I implemented the app using Flutter, enabling cross-platform development

• I integrated Geofencing and Google Maps

• I published the article "Dynamic (and Secure) Google Maps API Key in Flutter" on Medium, sharing insights and challenges faced during the project in regards to securely handling Google Maps API keys in Flutter applications

• I published the article "Geofencing in Flutter" on Medium, detailing the implementation and use cases of Geofencing in the app

A cloud-native implementation of how to measure agility using Kubernetes Deployment Frequency.

• Inspired by the book "Accelerate - The Science Behind DevOps: Building and Scaling High Performing Technology Organizations" (Forsgren, Humble, and Kim), I implemented this project to illustrate the concept of the KPI Deployment Frequency (DF) (or Throughput)

• I implemented the project using Golang and Kubernetes, demonstrating how to measure agility through Kubernetes Deployment Frequency

• I integrated Prometheus and Grafana for monitoring and visualization of deployment metrics
