Name: Vegard Kåsa
My career as an Oracle DBA startet in 2001, when I acceptet a request to take on the responsibility as my current employer's DBA. From that point and onwards, managing Oracle databases has kept me busy and engaged. I enjoy my work, and particulary appreciate the constant learning and devlopment that comes with the job. From 2014, I am self-employed through my company Oric Consulting AS (Norway), and from 2024 Oric Consulting AB (Sweden) I currently live in Göteborg, Sweden, with my family.
