"Achim Galeski is an inspiring, genuine, and hands-on leader. He is the kind that you know would go to bat for you and enjoys getting into the field with his team. He combines leadership so well with experience and deep technical know-how to manage a cross-functional and diverse team. With Achim, you are never standing still, and there are a ton of optimizations to reduce toil, improve automation, and have a lot of fun while doing it. In making decisions, he ensures to get valuable inputs from the team on potential solutions. In my time working with him, he has had an immense impact on my career, and really helped me excel at my work as a Cloud Administrator, and eventually as a DevOps Engineer by clearly defining how my work can align with the business’s goals, and then giving me a great deal of autonomy to get the job done. This level of detail and communication went a long way in getting my work noticed on many levels for various infrastructure improvements on AWS, architecture decisions, and cost optimization strategies that I helped implement. On any given day, Achim can be seen simultaneously driving a ton of different backend, frontend, and AWS cloud infrastructure topics without breaking a sweat. Achim is also 100% committed to getting results and enjoys getting down to solve problems that arise quickly and transparently. He works extremely hard, solves hard problems and pushes for designing solutions that scale beautifully over many users while being not overly complex if they are maintainable, fast, and long-term effective. I recommend him highly!"

"I worked with Achim for 4 years, where he not only migrated a formerly static system into the AWS cloud with an automatic vertical and horizontal scaling set up (quite some night shifts were needed for this) to accommodate also hugh traffic spikes, but also developed and set up a safe and secure tech-environment. As (product) partner in crime he developed quite some marketing requested features e.g. all kinds of coupon options, but also catering to customer, operation and customer service needs - all on this fast, precise and with dedication. Furthermore, he is dedicated to setting up and evolving his team catering to any of cultural and technical background."

Anna-Barbara Merkel, Head of Digital Product @ Invincible Brands

"Achim excels at concisely explaining and implementing technical solutions. Despite humbly referring to himself as a "Backend developer", his extensive knowledge of IT enables him to be equally as effective in DevOps and System Administration roles. He's the rare, sought after breed of Developer who's capable of both swift hot-fixes and meticulously crafted codebases. A pleasure to work with and someone whose feedback and input I always value."
