About

I am a dedicated and motivated Windows Server Administrator and Identity Access Management (IAM) professional with over 10 years of IT experience. Throughout my career, I have excelled in roles that require strong technical skills, attention to detail, and a proactive approach to problem-solving. My recent position as a Security Administrator at SYNOT Games involved defending systems against unauthorized access, performing vulnerability tests, and supporting security tools such as firewalls and antivirus software. Additionally, I have experience as an Azure DevOps Administrator, where I supported customer compliance issues, managed Azure infrastructure, and developed continuous deployment pipelines. Previously, I worked as an Identity & Access Management Engineering Operation Specialist at Bank Julius Bär & Co AG, where I onboarded applications to the IAM system, modeled business roles, and configured access in Active Directory. My experience also includes roles such as Application Service Desk Support at Frequentis AG, Windows Delivery Lead at DXC Technology Slovakia, and System Administrator at ANEXT. I have managed complex IT environments, provided technical support, and led projects that involved cloud migrations and service delivery improvements. My education in mechatronics further complements my technical expertise, enabling me to approach challenges with a comprehensive understanding of both software and hardware systems.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
