What I'm looking for

I'm looking to improve customer operations through KPI analysis, reporting, dashboard development, training, quality initiatives, and data-driven process improvements.

I'm leading training and quality coaching at H&M Group, where I coach 17 frontline agents, deliver new-hire training, and use Power BI to improve KPI performance, quality, and efficiency.

Previously at Wolt, I led support teams and coordinated local and outsourced operations, using Looker and quantitative metrics to guide performance conversations, root-cause analysis, and process optimization. I also managed onboarding, training, support content, and quality initiatives across teams while maintaining local guidelines and global compliance.

My background also includes guest experience, hospitality operations, and B2B sales and marketing. I'm building on this operational experience through a Master's degree in Strategic Business Analytics.
