What I'm looking for

I'm looking for a startup-style, flat environment where ideas can move fast and everyone has a voice and responsibility in decisions.

I've built backend and full-stack products at South Pole, Socialpoint, Veepee, and The Storytelling Company. At South Pole, I launched a carbon-emissions measurement and offset service, built its Golang backend with Event Sourcing and CQRS, and owned GCP infrastructure and Terraform automation.

I've shipped backend features for a mobile game serving roughly 4M MAU, built cart, checkout, fraud, and matchmaking services, and delivered interactive storytelling platform features across frontend and backend. I work best in startup-style, flat environments where ideas move fast and everyone has a voice and responsibility in decisions.
