• Collaborate with editorial and commercial teams for cross-functional solutions

• Python (yes, I'm becoming friends with snakes 🐍)
• AWS Cloud (preparing for the Cloud Practitioner certification)

• Custom ad modules (Sticky ads, leaderboard, box-in-text, fullsup, boxbanner, floating ads, banner overlays, takeovers, and bubble ads)
• AMP integration and validation pipelines
• Brightspot CMS (yes, with all the quirks it comes with)
• GitHub workflows and build pipelines

• I love combining creativity and logic to build ad experiences that don’t annoy people 🙃
