A number of valuable performance optimizations. One notable example would be optimizing spreadsheet calculation in an insurance company - the original one took the whole business day to complete (this was a while ago, on much older hardware), I managed to make it 3x faster. Another is a deployment pipeline with DB replication, which I managed to cut down from over 30 to a couple minutes.
Long time backend developer turned scrum master, looking to return to more technical roles. Strong proponent of code quality, TDD enthusiast. Notable projects include a fleet vehicle monitoring GIS application, real-time all-pay auction system and a highly customized CRM system for an automotive company.
