I build tools I use myself, and share what might help others.

Build: test automation tools and frameworks for web, desktop, mobile, and API; security-aware (OWASP).
Interested in: software architectures, design patterns, and their application to test frameworks and programs.
Beyond testing: Python applications, modern Python and CPython, efficient new libraries, and Rust as a hobby, little by little.
Stack: Python · pytest · Playwright · Selenium · CI/CD · BDD, TDD, type-driven & other testing methods · and much more.
Open to: collaboration and open-source projects.
