What I'm looking for

I seek roles building scalable, performant backend and live-service infrastructure where I can lead technical design, improve developer tooling, and support high-concurrency user experiences.

I am a Senior Backend Developer with 10+ years building and scaling live-service backend systems that support millions of users. I focus on performance, developer tooling, cross-discipline collaboration, and reliable infrastructure to deliver seamless, player-first experiences across platforms.

I've architected backend services handling millions of daily users and led LiveOps and incident response for global player bases, shipped end-to-end features, and built tooling and automation that reduced operational effort and latency across multiple companies and domains.
