At Blitz Growth, I built the lifecycle email programme from scratch on PostHog, with behaviour-triggered workflows across the user journey. I also found bot inflation in engagement reporting and fixed a silent trigger condition that had been dropping real signups from the welcome email.

At Joyride Games, I built a friend-online push campaign that prompted players to join friends in the game. In a 7-day test against a 15% holdout, it drove 2 to 3 more games per player and a 40% CTR, the app's highest.

I’ve also worked across Live Ops, behavioural segmentation, reactivation and marketing automation. I’m hands-on with funnel and cohort analysis, and used AI coding agents to deliver an influencer-matching agent with verified creator shortlists.
