Principal Engineer / Director of Engineering, Hands-On IC

January 2016 - June 2026 • Los Angeles until 2020; Remote thereafter

Principal Engineer, Feb 2024 - Jun 2026; Director of Engineering, Jan 2019 - Feb 2024. In both roles, remained a hands-on IC owner for architecture, implementation, production support, and modernization delivery.

  • Led hands-on modernization of a legacy Drupal 7/PHP/MySQL investment platform into React/Next.js, TypeScript, Python Lambda APIs, AWS serverless infrastructure, and Postgres/Supabase services.
  • Replaced legacy investor and admin workflows for account selection, qualification, accreditation, identity verification, funding, e-signature, document upload, investment records, distributions, tax documents, messaging, and support operations.
  • Architected and maintained a TypeScript/SST serverless platform with 80+ internal packages, 95 Lambda declarations, SQS/DLQ pipelines, S3-backed batch jobs, EventBridge schedules, Cognito authentication, KMS-backed flows, and Postgres/Supabase services.
  • Owned high-risk production workflows for investments, authentication, data sync, distributions, and operations across Drupal 7 modules, Python APIs, TypeScript Lambdas, SST infrastructure, and Supabase schema/RLS governance.
  • Built legacy-to-modern data integration between MySQL and Postgres/Supabase using event-driven sync, outbox patterns, idempotent handlers, retry/backoff logic, dead-letter queues, and operational diagnostics.
  • Worked across the full production surface: legacy Drupal/PHP modules, admin tools, serverless APIs, investor dashboards, data bridge services, infrastructure definitions, and deployment/debug workflows.
  • Hardened production operations with feature-flag kill switches, RLS/permission governance, schema-drift checks, CI validation, deployment runbooks, reproducible debug workflows, and primary escalation ownership.
