About Miłosz Engel

My name is Miłosz Engel. I am passionate about integrating and connecting stuff. I like facing new challenges, testing new environments and connecting different systems. Windows and Linux Debian boxes (both physical and virtual) are my favourites. I like solving problems related to Windows Server roles and services as well as Linux but some systems in particular. I’m not considering myself as Linux master but surely, I always do my best to fit the needs. On the other hand I consider myself a Windows Server Professional and in terms of Windows Server services and Windows Desktops I always follow best practices, good advices and opinions from other admins. I also like database stuff like performance, queries and procedures. Currently, I’m focused on integrating stuff and more architectural roles and tasks. My background, going through many different jobs, projects and tasks related to different areas of IT – helps me to accurately estimate workload in order to fulfil requirements. I always try to foresee possible problems and technical issues related to systems and applications and their integration. My programming and database skills help me to track issues related to data and applications and provide good resolution to problems as well as performance issues.
