Hi There, I have worked with Microsoft data technologies since SQL Server 7.0. Initially, I was a VB developer, but in 2000 I pivoted into a data role and since then I have worked on hundreds of projects using combinations of MS SQL DB Engine, Analysis Services, SSIS, SSRS, PowerBI, Tabular, Power Automate, Power Apps, and more. I have run my own consultancy company since 2012 and have a range of clients from just a few users to 5000+ users, across retail, automotive, public sector, and food production. I now split my time between -> Client Consultancy Engagements -> Client Data Solution Development Skills -> Training - Private and Public I am a regular speaker on Microsoft Data Platform topics and co-leader of the Cork SQL User Group, Cork PowerBI User Group, and Data Céilí. All of my talks and training courses are heavily influenced by real work problems and solutions that I encounter on a daily basis.
