I have been working in the IT department since 2015. Since 2023, I have held the position of IT Security Analyst at ista Technologies. My responsibilities include monitoring the network as well as the devices and identities within it using Microsoft tools such as MS Sentinel, Security Portal, and Azure Entra. I manage system vulnerabilities, prepare documentation, and strive to follow best practices in the field of cybersecurity. Previously, I worked as an Application Administrator. I use my mathematical and analytical skills in my work, which I was improving over the years. In year 2002 I’ve graduated Mathematics & Physics Department at The Silesian University of Technology in Gliwice. The same year I’ve started my job experience with ista Shared Services as a billing specialist in Polish and then English language working directly with departments located in USA. I’ve taken advantage that my company gave me to develop my skills and to fulfil my own ideas and I became a Team Leader in a year 2006. For almost 8 years I’ve learned a lot about team management, team work and work with the people. That was great experience that I will never forget. After these years I’ve received a chance to develop in a direction that I was always thinking about and it was IT. I’ve taken the opportunity and now I’m learning a new things in this area. I like to spend my free time with my family. We love to travel and watch movies together. I’m passionate about music, I collect vinyl records, and I eagerly look forward to summer festivals. I try to live an active lifestyle. My sports passion is triathlon, which, by combining different sports disciplines, helps me stay in good shape and develop mental strength, teaching perseverance and overcoming personal limitations.
