About

With over 16 years of experience in IT infrastructure and database administration, I specialize in managing complex systems and resolving challenging incidents swiftly. My expertise spans Red Hat Linux, Windows Server, Microsoft SQL Server, and PostgreSQL, among others. I am particularly passionate about Bash scripting and administering Linux servers, with a strong preference for Red Hat. My career has been defined by working on systems that require advanced technical skills and in-depth problem-solving abilities. Currently, as a DBA PostgreSQL/DevOps at Sopra Steria, I focus on automating and optimizing PostgreSQL services, ensuring high performance and maintaining quality standards. My previous roles at SoftSystem and Pratt & Whitney Rzeszów further honed my skills in database migration, IT infrastructure architecture, and system support. Fluent in both English and Polish, I bring a global perspective to my work, underpinned by a strong educational foundation in computer systems and networks from Politechnika Rzeszowska.
