What I'm looking for

I'm looking to lead engineering teams and architecture for products where reliable, scalable systems, practical delivery, and AI-assisted engineering can create meaningful outcomes.

I'm CTO at Revenge Games, leading 10+ engineers and the technical direction, delivery, architecture, and production reliability behind systems serving around 200K players and 50M+ daily transactions.

I've led payment products at OpenFabric, built transactional platforms at Fetch Technology, and delivered distributed systems across fintech, marketplaces, and digital products. I stay hands-on with incident response, cloud infrastructure, AI-assisted engineering workflows, mentoring, and pragmatic technical decisions.
