Work Experience

Gusto

Sr. Staff Software Engineer

Current Oct 2025 - Present
  • Designed and delivered an automated employee compliance auditing pipeline for Gusto’s HR partner experience, orchestrating multi-step checks (employee data, tax forms, background checks, time off, benefits, and more) and Kafka-backed event streams that keep downstream systems reliably in sync at scale.
  • Led evolution of our HR compliance data model and audits for fractional HR, adding role, W‑9, and offer letter status tracking so HR partners and downstream analytics have a richer, auditable view of each company’s risk posture.
  • Introduced ActiveRecordDoc-based documentation tooling into our Rails ecosystem (generator, configuration, exclusions, and CI step), enabling product teams to automatically validate and publish structured schema documentation into our data lake/S3 and raising the bar on data quality and discoverability across services.
