I'm a platform-focused engineer with 9+ years building high-availability services for consumer-scale products. I specialize in authorization and account-related capabilities, decompose legacy architectures, and deliver composable APIs that internal teams can reuse across surfaces. I lead cross-functional initiatives with Product, Security, and Compliance, turning ambiguous requirements into practical designs and incident-driven operational practices. I love building reliable Go-based backends and scalable architectures that handle millions of requests in production.…I'm a platform-focused engineer with 9+ years building high-availability services for consumer-scale products.
