01
Test deeply.
Quality starts long before the first assertion. It starts with sharper questions, the edge cases nobody thought of, and a feel for exactly where software breaks.

Building software
worth trusting.
I'm Julia Pottinger. I've spent over a decade in QA, testing real products, finding the gaps teams miss, and turning messy releases into something safer to ship. Now I build my own products too, including AI tools, mobile apps, and games, and I share the practical lessons as I go.

How I think about quality
The beliefs behind my work.
02
Automate what matters.
Not everything deserves a script. The craft is choosing the high-value paths and building a suite your whole team actually trusts and maintains.
03
Ship with confidence.
When testing and automation pull in the same direction, release night stops being scary. That calm is the entire point, and you can learn it.
04
Drive the tools, keep the standard.
The tools got faster, and they will write the test, run the suite, and open the pull request. They cannot decide what is worth trusting. I drive them and keep the standard, because speed without judgment is just faster guessing.
05
Share the how.
Knowing something is only half of it. Showing another person how to do it, in plain steps they can follow, is the part that lasts.
06
Stay curious.
The best testers keep asking what if. Tools and frameworks change every year, but the habit of poking at the edges is what carries across all of them.
Meet Julia
A builder, educator, and endlessly curious human.
I test. I build. I teach. Over a decade in software quality led me here, and now I create my own products too, from AI tools to mobile apps and games.
I love sharing what I learn through articles, courses, talks and YouTube. The goal is simple: make testing, automation and building products feel clearer for the next person doing the work.
Beyond the blog
Things I build.
I don't just write about shipping quality software. I design, build, and ship my own, under my studio.
Start with the problem
Tools and guides for testing what matters before you ship.
Pick the thing your team is wrestling with right now: a test strategy, a stronger API safety net, or a better way to use AI without lowering the bar.
API testing Check the layers users never see. Walk through request inputs, auth, contracts, errors, data quality, and observability. Use the checklist Locators Write selectors that survive a redesign. Grab the right CSS, XPath or WebdriverIO selector, with a priority order that keeps tests from flaking. Open the cheat sheet
