What I am all about.

Current Focus
Cloud Transformation, Operational Excellence, Resilience, Cost Efficiency, Security, Zero Trust, Developer Productivity, Environmental Impact

What I do
Cloud & IT Transformation, Analyzing and optimizing Processes, Business transformation, Cloud Foundation, Security, Governance (aka Landingzone), Developer Experience, and how to build it reliably and maintainable with a focus on automation and software-defined infrastructure. The goal is to enable teams to self service and operate production. I am cloud-agnostic but focus mainly on GCP, AWS, and Azure or a combination also with the occasional Datacenter. I bring a strong background both in Software Development and Architecture, but also how to operate and govern all of that in different regulated environments. With that background, business and product are always the most important aspect, while all else has to make them succeed.

Happy times!

"If you're looking for a curious mind that can puzzle through the most difficult issues with streaming data processing pipelines, or just core system infrastructure questions, then Sandro is for sure the person you want to talk to. As a freelancer his contributions allowed us to avoid several dangerous paths, and his contributions were so valuable we tried to convince him to join us full time!" , Jeff Katz - Entrepreneur, Technologist, Engineer

"Having worked with Sandro for over 10 years now, I can say with certainty that he knows what he's doing. Proficient in a range of technologies, always up to date, he also knows when to use existing frameworks and when to write your own. You're guaranteed to get no-nonsense, rapid development and a clear vision. Look no further!" , Anatol Ulrich - Digital Wizard

"I worked with Sandro at solarisBank A.G. He is a dedicated professional, extremely well versed in different aspects needed to build a solid software system. No matter if it's "just" coding or distributed system architecture, Sandro is the guy to go to. If you are looking for someone who will deliver on all fronts, I would wholeheartedly recommend having Sandro on your team." , Armin Pašalić - Software Engineering Team Lead

"Sandro is a great guy with a lot of ideas and loads of technological knowledge. He quickly understands problems and find appropriate solutions for that without loosing focus. I would recommend him to everybody who needs a problem-solver and/or somebody to drive the projects to success." , Jan de Cooman - Staff Engineer

"I have known Sandro for some time now and last year I had the pleasure of working directly with him in our Solution Architect team here in Germany on several large projects. Sandro has what I consider to be an outstanding expertise which he has been able to apply very successfully and profitably in our daily project work. Sandro convinced and supported with these skills the most difficult project situations in the preparation phase as well as internal and external implementation - I have rarely experienced such a profound expertise in the architectural environment. The interaction with Sandro was always impeccable and professionally refreshing. Complex project scenarios could be implemented with his help, packaged in easy-to-understand work packages, to full customer satisfaction. Due to Sandro's quick perception and his distinctive analytical thinking, he was able to recognise the essentials at any time and grasped even the most difficult correlations. Sandro was always fully committed and able to convince us with his excellent motivation and extraordinary enthusiasm. In situations with a heavy workload, he always proved to be able to work under unrestricted pressure and was always available to us in word and deed. He fulfilled the planning and control of his tasks extremely quickly and in an extraordinary manner, not least because of his impressive organisational talent. He acted independently, with extreme care, concentration and flexibility. Trustworthiness and absolute reliability characterized his working style at all times. Due to his unrestrictedly friendly and balanced nature Sandro was highly appreciated by everyone. He was always helpful, courteous and, if necessary, put personal interests aside. His behaviour in the team and towards customers was without exception exemplary and always loyal. I would work with Sandro again at any time and I can say that he is missed by everyone here in the team." , Patrick Pächnatz - Principal Security Architect

"Having Sandro on my team while building new IoT solutions at Telefonica was a lifesaver. No matter what the issue or language in question, he tackled the issue by coming up with clever solutions. The definition of a great engineer. He is the first to volunteer to learn new technological advancements and apply them to make efficient software that will scale." , Karen Nemeth - Bringing the World's Wonders to VR

"I's been an amazing experience to work with Sandro in the same team. He's a really proficient guy in the technical field, and also and easy going person always willing to help. He knows his stuff and how to proceed to do things right, with high quality standards. He's also not afraid to say how things can be improved in a positive way, leading the works to get there. I've found in him a highly valuable asset when it comes to bring software development projects to a success." , Mariano Navas - Scala guy, Blockchainer, FP junkie, nerdy by nature, Monads 4 everything

"I have been working together with Sandro at Geeny. During this time, I have come to appreciate him as both an individual as well as software architect. His pragmatic approach to problem solving and efficiency of finding solutions that just work is outstanding. He is well versed with a number of technologies and follows industry trends closely to keep his skills sharp and up-to-date. His leadership style and persona makes him a very valuable addition to any team. I would always recommend him for any projects he chooses, as I believe he will have a positive impact on both the culture and development speed of any team." , Marcelo Grebois - Cloud Infrastructure Architect, Daimler Mobility Services

Batman would be jealous.

Distributed Systems

This is where I grew up as a professional programmer. How things communicate has always been my favorite topic and inspiration here comes from all areas. It's simply fun to do this well.



It has always been about data. Be it in the past with 3D Engines having different optimizations, but similar problems. Sometimes a lot, when you consider CUDA here. But its not just about speed.


Mobile / Web / Frontend

Having also wandered into the Art School in Dresden, there was no way around not also getting my hands dirty with frontends. It has been fun, not something I need to do much anymore, but it helps me a lot in other endeavors.


Embedded / IoT

It's a fun market. Those little things, that have hardly any power and you still need to save energy. But again, connecting them is where the fun is for me. Who wants the single master node, where your home can be hacked? Scary.



Having done all kinds of things helps a lot. Finding the right tools and evolvable architectures to solve problems efficiently and maintainable is my key focus. It's fun. You can make me use UML, but I think, we can find better ways to communicate.


Security & Privacy

Who wouldn't want that! Freedom is good and all that, but you know the drill.


Those pesky little things.

Where was my swatter...
