ABOUT ME

As an SAP Basis Consultant, I focus on making sure SAP systems run smoothly and efficiently. This means handling everything from installations and upgrades to ongoing technical maintenance across the SAP landscape. I also take part in key technical discussions about SAP’s future direction. With over 14 years of experience, I’m proud to consistently deliver projects that meet—and often exceed—customer expectations, reflected in my 100% customer satisfaction rate. My approach is straightforward: I stay positive, dive into the details, and ensure quality in everything I do.

Over the years, I’ve had the pleasure of working with multinational clients and teams, exploring the latest SAP and database technologies on a range of operating systems. Beyond the day-to-day, I’m passionate about SAP solutions, cloud-based technologies, and the Linux ecosystem, and I’m always excited to dig into new challenges and solutions in these areas.

Jan Hrusovsky

SAP Basis Consultant

I’m proud of my strong work ethic, which shows in my ability to quickly pick up new concepts and reliably get the job done. With a solid background in SAP system administration, I bring a lot of hands-on experience to any team, making me a trusted asset. I enjoy setting and surpassing goals, approaching every task with an organized, structured mindset. Even in high-pressure situations, I’ve consistently completed a wide range of SAP projects. I’m committed to teamwork and seek out challenges as opportunities for personal and professional growth.


I especially enjoy working on diverse projects, particularly those involving system upgrades, migrations, and other complex initiatives. Challenging projects are my favorite—they keep me motivated and provide chances to push boundaries, develop new skills, and deliver impactful solutions.


In terms of latest certifications, I earned the AZ-104 Microsoft Certified: Azure Administrator Associate in February 2022, the AZ-120 Microsoft Certified: Azure for SAP Workloads Specialty in July 2022, and the Associate Google Cloud Engineer certification in December 2023.
