• API

  Label purchasing API

  An API that takes a shipment, applies shipping rules, and buys the label in a single call. I built the rules engine that makes the decision and the Postgres-backed workflow that carries out the purchase, so a call that fails partway through can be retried or restarted without buying a second label. I also instrumented the service with OpenTelemetry and wrote the end-to-end check that gates its deployments.

• Pipeline

  Carrier reconciliation platform

  Carriers send invoices in formats that don't agree with each other. This platform ingests those files, normalizes them, matches each charge to the label it belongs to, and publishes the results as billing events, refund events, and partner reports. I was a founding engineer on it. I built core pipeline stages and the events that connect them, automated ingestion so new files process without manual steps, extended coverage to nine carriers and to customers' own carrier accounts, and was responsible for keeping the system correct, recoverable, and within its SLOs.

• Agent

  Reconciliation analyst

  A Slack agent for reconciliation investigations, built on the Claude Agent SDK and running in production at Shippo. Ask it a question in a thread and it hands the question to a read-only analyst subagent that can query Databricks and New Relic through MCP, then streams the findings back into the thread as structured results.

• Tooling

  Wiki harness

  A Claude Code plugin that turns merged pull requests into design documentation grounded in the code that actually shipped. After a merge, a CI job runs the harness and opens a documentation PR; a set of reusable skills, workflow hooks, and validation keeps the docs consistent as the codebase changes. Several engineering teams at Shippo now use it.

• Infra

  Service platform and infrastructure

  The AWS infrastructure for four production services on EKS, built and operated as code: IAM and OIDC, databases, messaging, secrets, Helm deployments through Argo CD, canary rollouts with Argo Rollouts, and the New Relic dashboards and alerts that watch all of it.
