PROFILE
Steve Kowalik
Worked on stabilizing and modernizing Python test suites across two major open-source repositories. In stripe/stripe-python, addressed a breaking change introduced by PyTest 9 by removing an obsolete mark from the async_http_client fixture, which improved CI reliability and ensured forward compatibility as testing tools evolved. Later, in PostHog/posthog-python, removed the six dependency to streamline Python 3 compatibility and updated tests to use unittest.mock, reducing external dependencies and simplifying future maintenance. Demonstrated a disciplined approach to software maintenance, focusing on Python, pytest, and unit testing to enhance codebase reliability and maintainability while supporting ongoing project evolution.

Apr 1, 2026April 2026 (2026-04) — PostHog/posthog-python: Delivered a foundational dependency cleanup and Python 3 compatibility improvement. Removed the six dependency and migrated to native Python features, paired with modernized tests that use unittest.mock instead of mock. This reduces external dependencies, simplifies maintenance, and positions the project for smoother Python-version upgrades. Commit c2962557cb262785813a7e9232530ad78147ac0d documents the change and provides traceability.
