Quality engineer · Product-minded builder · Seattle

I build software and quality systems for things that are hard to see clearly.

I turn messy workflows into tools people can trust, from enterprise data migration and test automation to a live map for following wildlife sightings around Puget Sound.

Selected work

A few things I have built and improved.

Products, systems, and workflows where good quality work made a complicated problem easier to understand.

02Working prototype

Kepler

An orbital mechanics sandbox that turns real trajectory planning into something visual and tactile.

Built with a tested physics core, direct-manipulation maneuver nodes, and live mission-time playback.

Quality systems

I build quality practices around the way a system actually works, not around a test count.

That has included migration validation across more than eight teams, shared automation frameworks, and practical AI-assisted workflows.

How I work

Understand the whole system. Then make it easier to trust.

01

Start with the whole system.

I map the users, data, handoffs, and failure paths before choosing a test or a tool.

02

Turn repetition into a tool.

I move useful work from exploration into reusable workflows and deterministic checks.

03

Verify the output.

I review, run, debug, and preserve the rules that future changes need to keep.

Experience

Quality work across products, platforms, and teams.

CHG Healthcare

Senior SDET

Built quality strategy and validation for a complex Salesforce migration, coordinating risk and coverage across more than eight engineering teams.

Operations and supply chain

Built the systems instinct

Learned to see how people, tools, inventory, and process fit together long before I started writing software.

Outside work

I am usually doing something physical or looking too closely at the natural world.

01

Acrobatics

I have spent years training, performing, and teaching partner acrobatics. It is a practice in trust, clear feedback, and staying calm while solving a physical problem.

02

Trail running

Long days in the mountains are how I reset. I like the patience and steady problem solving of covering a lot of ground under my own power.

03

Wildlife photography

I photograph wildlife around the Salish Sea. Paying attention to movement, conditions, and small changes is also part of what led me to build Spyhop.

Let’s talk

I am looking for senior quality engineering, SDET, validation, and test automation work.

Especially where quality, product thinking, and AI-assisted engineering overlap.
