About Sergei L.

I’m a Software Development Engineer in Test (SDET) with 7+ years of experience designing and maintaining automation frameworks that improve software quality and speed up release cycles. My background includes fintech and machine learning products, where I’ve worked on building UI, API, and database test coverage using tools like Playwright, PyTest, Cypress, and WebdriverIO.Much of my work involves integrating automated tests into CI/CD pipelines (GitHub Actions, Jenkins), validating Kubernetes deployments, and ensuring API security through structured post-deployment testing. I’ve contributed to large-scale projects by improving regression stability, increasing test coverage, and reducing manual testing efforts across teams.I value clarity in test design, stability in automation, and tight collaboration with engineers, product managers, and DevOps. I’ve also helped QA teams improve their approach to debugging, test case design, and framework scalability.Always learning and improving—let’s connect if you want to talk QA or testing strategies!Proffesional SkillsProgramming: Python, JavaScript, TypeScript, SQL, MongoDB, Node.js Frameworks: Playwright, Selenium, PyTest, Cypress, WebdriverIO, Protractor, Appium API Testing: REST API, Postman, Swagger CI/CD & DevOps: Git, GitHub, GitHub Actions, Jenkins, AWS, Docker, Kubernetes, Datadog Testing & Tools: Gherkin, Cucumber, Jest, Mocha, TDD, BDD, TestRail Agile & Management: JIRA, Confluence, Scrum, Kanban IDEs: VSCode, PyCharm, WebStorm, IntelliJ IDEA
