Summary
👤
Senior🎓
Top SchoolNorman Dunbar is a seasoned Oracle DBA with over 21 years' experience who now blends database expertise with hands-on electronics and technical authorship from his base in Buckie, Scotland. Retired from day-to-day DBA work, he continues to contribute to open-source projects (notably improving ANTLR grammars for Oracle TNS parsing) while publishing technical books on Arduino for Apress and researching low-level microcontroller topics. His career spans large-scale migrations, cloud moves and legacy system support for clients such as Capita, the Environment Agency and Morrisons, and he often automates manual processes to reduce risk and effort. Known for mentoring and pragmatic problem-solving, Norman pairs deep systems knowledge with a tinkerer’s curiosity—equally at home tuning Oracle performance or dissecting microcontroller internals.
