Work

Ten years of building software, mostly on the infrastructure side of product teams. A one-page résumé is available as a PDF.

2023 — now
Staff Engineer, Platform

Northlight · San Francisco

Technical lead for the platform group: developer tooling, data infrastructure, and the interfaces product teams build against. Roughly nine engineers across three teams, none of whom report to me.
- Designed and shipped Ledger, the schema change system now used by most of engineering.
- Led the migration off a shared monolithic database to per-domain stores, over eighteen months, with no customer-visible downtime.
- Set up the incident review practice; wrote the first thirty reviews myself so the format had something to imitate.
2022 — 2023
Senior Software Engineer

Northlight · San Francisco

Joined to work on the billing rewrite and stayed for the infrastructure. Built the usage metering pipeline that still bills every customer today.
- Rebuilt metering as an event-sourced pipeline; cut billing disputes by 70%.
- Reduced p99 checkout latency from 2.4s to 380ms by moving pricing evaluation out of the request path.
2021 — 2022
Software Engineer, Payments Infrastructure

Meridian Labs · Remote

Ledger and reconciliation systems for a payments platform moving billions a year. Built Halyard and owned it through two processor integrations.
- On-call for the ledger; wrote the runbooks that made that survivable.
- Introduced property-based testing for money math after a rounding bug cost us a very uncomfortable week.
2020 — 2021

Co-founder & Engineer

Foundry · San Francisco

Built the product, talked to users, raised a small seed round, and wound the company down when it became clear we had built something admired rather than needed. Details on the projects page.
2016 — 2020

Software Engineer

Cartwright & Co. · Seattle

First engineering job. Internal tools, then the API platform. Learned to write code other people could maintain, largely by having to maintain my own.

Tools I reach for

Daily: Go, TypeScript, Python, Postgres, SQLite. Often: Rust, Kafka, Terraform, Kubernetes, OpenTelemetry. Comfortable but rusty: Ruby, Java, Elixir.

Languages are the easy part. What I actually care about is instrumentation, reversible deploys, and schemas that describe reality.

Education

B.S. Computer Science — University of Washington, 2016.
