About me


“Digital transformation should be like a caterpillar turning into a butterfly, but too many orgs are only aiming to be fast caterpillars.” With this little quote from George Westerman, Principal Research Scientist at MIT, welcome to my website.

My name is Michael Höller - I would like to give wings to the digitalization of your company and turn your ideas into a butterfly! For more than 20 years I have been working as an independent software architect, developer, and consultant.

Many companies are reinventing themselves in these times of Industry 4.0 to employ digital transformation trends, necessary cloud strategies, and IoT. Particularly small and medium-sized enterprises, but also many startups, are suddenly faced with tasks that have little or nothing to do with their actual core business. More and more, you may find that MongoDB, serverless architectures, data lakes and data visualization are overwhelming your daily job duties. You may find yourself slowly losing track between data analytics, Docker, Jenkins, the decision between on-premise or cloud and countless microservices. If this sounds familiar, then now is the time for a dedicated IT professional with a broad wealth of experience.

Whether it’s logistics or telecommunications, electronics or chemicals, or sales and marketing, I'd love to help your development teams design, build, and deploy high-performance solutions.

As a MongoDB Champion with a passion for agile and innovative technologies, I am actively engaged with the open source community - fostering the adoption of flexible and scalable databases while providing technical support for business decisions.

In interdisciplinary projects, stands for an analytical, process-oriented way of working and for solutions that do not simply meet customer demands, but rather exceed those demands to fit seamlessly into existing IT landscapes. As if they had always been there.

I look forward to actively supporting your company soon!
Michael Höller
