I build reliable web and API test automation with Python, Playwright, and CI/CD.

At Lab80, I increased automated coverage from 0% to 90% on one project and delivered automation across four projects. I design coverage plans, estimate testing effort, and build tools that help QA teams move faster.

I've built Python pytest and Playwright frameworks for web applications, structured with the Page Object Model, alongside Bash-based checks for specialized testing. I also developed a Moscow Exchange integration, expanded a trading strategy testing framework, and automated validation of new functionality.

I create practical CI/CD automation: agent- and daemon-based orchestration, scheduled test pipelines, automated reporting, and TMS result publication. This reduced incident response from several hours to tens of minutes, while Docker-based component containerization expanded resilience and integration testing coverage.

Previously at UKTECH LAB, I grew API regression coverage from 20% to 85% through 300+ Postman tests, prepared suites for Jenkins, and automated OWASP DAST checks with pytest and the OWASP ZAP API. I also support QA delivery through test design, code reviews, troubleshooting, and hands-on technical leadership.
