It is his profound understanding of hardware, Linux internals and the mechanisms that underlie database systems that make him an invaluable professional. Working with Daniel is an educational experience and – if I may add – a sheer pleasure. Daniel has also consulted us on hardware procurement and setup, where his knowledge saved us long time of research and negotiations." and "Daniel is the type of DBA that doesn't looks only at the SQL query and thinks how to optimize it but also asks "what is the business purpose of this query/Procedure". He's always connected to business needs of the DB/IT infrastructure."
