Catch the bug before your users do.
I build automated web UI and API test suites that run on every pull request, so your team can ship faster without the release-day surprises. Test automation and QA consulting for software and firmware teams.
What I do
Testing work that pays for itself in fewer hotfixes and calmer releases. You own all of the code and documentation when we're done.
Web UI automation
End-to-end browser tests for your web app with Playwright, Selenium, or Cypress: logins, forms, checkouts, and the flows your users depend on, across Chrome, Firefox, and Safari.
API test automation
Automated checks for your REST and GraphQL endpoints with Playwright or pytest, catching broken contracts before the UI ever sees them.
CI/CD test pipelines
Tests running automatically on every change in GitHub Actions, GitLab, Jenkins, TeamCity, or Codefresh, and test gates in Argo CD and Kargo deployments. Clear reports, plus fixes for flaky and slow tests so people trust the results.
QA audits
A review of how you test today, the gaps that matter most, and a prioritized plan to close them.
Embedded firmware testing
Unit and hardware-in-the-loop test harnesses for C firmware.
Software builds
Internal tools, small web apps, scripts, and integrations, built with tests from the start.
Packages
Fixed prices so you know the cost up front. Custom work and hourly consulting are available too.
| QA Audit | $1,200 | A review of your current testing, a written gap report, and a prioritized roadmap. About two weeks. |

| QA Retainer | $1,800/month | Ongoing test maintenance, new coverage as you ship features, and release checks. |
Fixed-price projects start with a 50% deposit.
How we work together
From first message to running tests, usually within a few weeks.
A short call
You tell me what you're building and where bugs are getting through.
A written scope
A clear statement of what I'll deliver, by when, and for how much.
Tests that run
Regular updates while I build, then a handoff so your team owns it.
About
- Software Engineer in Test
- Games and embedded firmware
- Orange County, California
- Working remotely with US teams
I'm Kevin Nguyen, a Software Engineer in Test. I've built test automation for large games and for embedded firmware, from UI and API suites to unit tests that run on the hardware itself.
I take on a small number of consulting projects at a time, so you work directly with me from the first call to the handoff.
Sample project
A public example of how I structure a test suite: 17 Playwright UI and API tests against public practice sites, running in GitHub Actions on every push and pull request. It's a sample, not client work.
