👨‍💻 About Me

I'm a Senior Software Engineer with 10+ years of experience building backend platforms, distributed systems, and internal developer tooling.

I've built authentication platforms, enterprise integrations, event-driven systems, feature flag platforms, and developer tooling used by engineering teams at Hyatt.

I enjoy designing systems that are simple, scalable, and easy for other engineers to build on.
