  As the first engineering hire, I helped build Vouch’s core technology platform. It supported hundreds of millions of dollars in gross written premium.

  • Designed and built the policy administration system around an event-sourced engine that handles pricing, billing, and endorsements.
  • Developed the underwriting, quoting, and document-generation workflows, plus a recommendation system for coverage selection.
  • Built an internal prompt-management system that powers AI workflows across the platform, using FastAPI, LangChain, and OpenAI.
  • Led the build-out of the infrastructure platform: CI/CD pipelines, AWS infrastructure, and monitoring and alerting, supporting over 80 services.
  • Worked across the full stack: React, TypeScript and Python services, Rails APIs, and AWS.

  Product Engineering

  • Built an event-driven application in Clojure and Kafka Streams powering investor loan-part ownership, borrower repayment distribution, and the public Investor API. Repayment distribution went from hours to seconds.

  Infrastructure & Engineering Effectiveness

  • Migrated production workloads from Chef-provisioned AWS instances to Docker containers running under Mesos, Marathon, and Chronos.
  • Built a CLI tool that detects and deploys application dependencies automatically, so engineers could spin up production-like AWS environments for integration tests across dozens of services.
  • Replaced long-lived static secrets with short-lived per-container dynamic secrets using Vault and envconsul, with a PR-based permissions workflow reviewed by Security.
  • Deployed and operated Mesos, ZooKeeper, Kafka, and Consul clusters on AWS with Terraform. Supported 200+ microservices across 3 regions.
  • Built logging and monitoring pipelines (~500M logs/day), standardized Jenkins Pipelines, and ran an internal HAProxy/Consul service mesh.
