Hi, I'm Axel

I'm a serial entrepreneur, public speaker and software development expert based in Munich.


I am the founder of CloudCaptain (previously known as Boxfuse). Our self-service cloud deployment platform enables hundreds of small and medium size companies to focus on development, while we take care of infrastructure and operations. CloudCaptain reliably and securely provisions our customers' applications in the AWS cloud and updates them with zero downtime thanks to our unique immutable infrastructure with minimal fully baked machine images approach. We also take care of all supporting resources including elastic IPs, load balancers, databases, security groups, DNS and more so that our customers can focus their attention where it matters most: delighting their users.


In 2010 I also created Flyway, and grew it into the world's most popular database migration tool. By late 2017 I extended the project beyond its open-source roots and turned it into a very successful business, acquiring many of the world's largest companies and public institutions as customers for the new commercial pro and enterprise editions we launched. After just under two years of very rapid growth, I sold the company to Redgate in 2019.


In the past I have also spoken regularly at many large international conferences including JavaOne, Devoxx, Jfokus, JavaZone, JAX and more about a wide range of topics including modular monoliths, immutable infrastructure and continuous delivery. As part of this I received the JavaOne RockStar speaker award and thanks to my broad industry contributions I was elected Java Champion by Oracle.

Over the last few years, I have given a large number of talks at conferences and user groups.
The focus has been Modular Monoliths, Immutable Infrastructure, Continuous Delivery, Flyway and Boxfuse.

This talk is pure Gold. This talk must be mandatory for every software developer. Thanks for this tremendous knowledge
Waldo Araya at Devoxx Belgium 2018 in Antwerp
A masterclass in my opinion. Especially relevant in my home country of New Zealand where we have a small population (under 5 million) so the vast majority of software written to serve subsets of that population does not need the rather costly benefits that come with microservices.
