About

I'm a Data Engineer II at AppFolio Inc, focused on building and scaling data platforms that power business-critical decisions. I specialize in designing resilient data infrastructure, implementing observability at scale, and turning complex data challenges into maintainable systems.

With experience spanning the full data lifecycle, from ingestion and transformation to governance and monitoring, I approach problems with a platform mindset: build once, scale reliably, and make it observable.

/* Engineering Principles */

  • Design for scale, build for maintainability
  • Observability is not optional
  • Data quality starts at the source
  • Automate the toil, focus on the craft
