05 / About Stephen

Independent by design.

I'm Stephen Horsfall, the independent protocol engineer behind Ceno Studio.

I've built onchain systems since 2018, from AMM contracts and governance to indexing, interfaces and live network deployments.

Ceno is deliberately small. When you hire the studio, you work directly with the person responsible for the technical decisions and the code.
