8+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.Tech Stack

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. “
