Summary
👤
Senior🎓
Top SchoolOleksandr Korsun is a Senior UI Automation Architect with over 10 years of experience building resilient test automation across banking, e-commerce, retail and fintech domains. He designs and implements data-driven BDD UI automation frameworks from scratch using tools like Selenium, Playwright, WebdriverIO and Robot Framework, and is fluent in Python, Java, TypeScript and supporting CI/CD stacks (Jenkins, Azure DevOps, TeamCity, GitLab CI). His work has driven measurable quality improvements—reducing production crashes by ~40% and cutting support tickets by 30%—by embedding robust regression, exploratory and acceptance testing into delivery pipelines. Based in Old Toronto, he combines hands-on scripting with architectural thinking to scale test suites for complex web applications at Barclays and prior employers. A pragmatic mentor and cross-functional collaborator, he consistently lifts QA capabilities across teams while keeping a strong focus on test maintainability and continuous improvement. Less obvious: he often blends lightweight observability checks into UI tests to catch integration regressions earlier, bridging gaps between QA and SRE practices.
