About me
Senior QA engineer with 5 years of testing experience and a Python development background. I test web apps, mobile apps and APIs end to end, and I go deeper than the UI: I check the API, the database and the logs to find the real cause of a bug.
What I can do for you:
- Manual and exploratory testing, test plans and test cases
- API testing (REST, Postman) and SQL data checks
- Python scripts for test automation, data checks and backend tasks
- Small Python/Django backend features and fixes
Clear bug reports and fast communication.
