Über mich

Secure, scalable and maintainable architecture is always my goal at my work.

I have for example helped a big bank to succeed in their big data analysis and projects related to that, I've helped a big European online retailer to implement technical architecture to scale their subscription based business European wide and I've also helped small startups to build their software products from scratch.

During the course of the last three years I've used and most enjoyed working with Kubernetes, Kafka, Elastic, Platform Engineering Azure and software architecture.
