What I can do for a team
-
Build and ship
Features, fixes and production releases on a codebase too large for one head.
-
Test strategy
What to test, how, and when it is enough. Web, mobile, API, performance.
-
Automation
Playwright, Cypress, Selenium, Appium, REST Assured and JMeter.
-
AI output validation
Judging what a model produced, from video generation against an SLA to agricultural forecasts.
-
Running the team when needed
Scrum Master and Product Owner when a team needed one. Ceremonies, backlog, the client call.
What I’m doing now
An enterprise platform for a global management consultancy, under NDA. A very large codebase and many teams.
The work stopped looking like classic QA a while ago. I am not a career developer. I know the product, and I know how to ship.
