What I do

At Sporty Group, an iGaming and sports-betting company, I work in the Boot Team and test the platform end to end: sign-up and identity verification, payments, bets, casino games, bonuses and security. I also own the release quality of each new country the platform launches in.

Before that I spent seven years at Authority Partners as a senior QA consultant and team lead for international clients, building QA teams from scratch and taking responsibility for release readiness on enterprise and SaaS platforms.

I also co-founded Masters of Testing, a company that provides test strategy, test automation and quality engineering to software teams.
