Projects

Selected work and explorations in Python test infrastructure and AI-assisted test engineering.

Selected work

Work and personal projects selected for their engineering questions; each retains its actual stage.

Payments test APIs and shared SDK

Work case · Maintained

Share request behavior across business APIs while handling protocol changes, existing callers, and retry conditions.

Contributed to APIs and led the merchant-funds SDK refactor and compatibility work.

XAT · Python API testing

Personal project · In progress

Follow discovery and report validation through concurrent failures, deadlines, and missing results.

Defined scope and execution behavior; collaborated with AI on implementation and code review.

Ongoing practice

Work being developed, maintained, or documented; write-up status is separate.

AI testing workflow

Work case · In progress · Write-up in progress

Connect staged LLM generation, human review, and execution checks to turn generated code into useful test cases.

Build a staged LLM test-generation pipeline at work, combining AI-agent delivery with human review gates.

Exploration

Study, design, and planned experiments; inclusion does not imply completed experiments.
