About

I develop Software for a living. I'm enthusiastic about Kotlin and Spring Boot. I personally think that Android is the superior Mobile Operating System (for now...). In my spare time i run, climb and travel as much as i can.

Work Experience

Senior Staff Software Enginee - Mobimeo (former ReachNow), Berlin (10.2019 - Present)

Joined the pay-squad in the pre-merger ReachNow(✝) days. Maintaining and extending 4 fully Kotlin-written Spring Backend micro-services and a Angular written administrative Frontend. ReachNow's Tech department was later acquired by Mobimeo which also operates in the sector of multi-modal transportation.

The micro-services have been completely rewritten overtime to be fully reactive using Project Reactor. Assured tractability and observability with de-facto open source tooling like Grafana and Prometheus.

We used state of the art frameworks such as

Initial build using Jetbrains Teamcity CI and deployed to AWS ECS and currently build with GitHub Actions and deployed to a managed Kubenetes Cluster.

Software Developer - AOE GmbH, Wiesbaden (07.2015 - 09.2019)

I started out as Java Spring Backend Developer for the Congstar App when i joined AOE.

After the first stable release i joined the Congstar Android App Team. The task at hand was to write a native app from scratch to replace the old hybrid.

We used state of the art frameworks such as

The app got released and after a maintaince window i moved on towards helping to migrate the web app backend away from a monolithic php application towards a Spring Boot driven mircoservice architecture written in Groovy and now in production.

Moving on to the help with AOE's internal Project OM3. I've build and maintained several smaller mircoservices with Spring Boot (some with RabbitMQ integration) and AWS Lambda Functions in Kotlin. Everything build with GitLab, Jenkins and deployed into a Kubernetes Cluster.
