Python and PyTest test automation for APIs, integrations, regression and CI/CD. Test frameworks and QA consulting for product and engineering teams.
Discuss your tests
Overview
I build Python and PyTest tests that help catch errors before release. I connect product requirements with API, integration and workflow testing in CI/CD.
Starting point
For teams slowed down by manual regression, broken integrations after updates or unclear results from existing tests.
Scope
Cross-system workflows: the contract, the response content and the record in the target system.
Repeatable checks of important features after changes, with controlled data and a known initial state.
Error, timeout and recovery scenarios that show how the system returns to correct operation.
Test runs in your release process and a report showing where and why a result differs.
Example
A new API version changes a response field. The calling service still receives status 200 but no longer saves correct data. The test verifies the contract, the response content and the record in the target system.
Working together
We start with the important workflows and your current release process. We agree what to automate, which data is needed and what a correct outcome looks like.
I prepare the Python/PyTest test structure, integrations and run instructions. Maintainable tests need shared requirements, controlled data and reproducible failures.
I connect the tests to your release process and reporting, and show your team how to add further scenarios.

Engagement
Repeatable scenarios are good automation candidates. Exploring new behaviour and evaluating user experience still require human testing.
If you already have tests, I start by reviewing their structure, execution and results. The scope can cover fixing or extending your framework without rebuilding it.

Yes. I first review its structure, execution and results. The scope can cover fixing or extending existing tests without rebuilding the whole framework.
Over 15 years working with devices, networks and data systems, including Samsung and Dell and projects for Intel and Cisco. The home page describes this experience.
Start with the problem
What isn’t working in your tests today? Describe your tools and the outcome you need. That is enough to agree the first step.
