I’m Anastasios Tilsizoglou, a Test Automation Architect and Principal Test Automation Engineer with 7+ years of experience designing automation frameworks and platforms used by entire QA organizations. I’ve been the go-to technical authority for automation architecture and delivery standards—turning strategy into shared tooling that helps multiple teams move faster with confidence. I also build AI-driven QA infrastructure, combining governed agentic workflows with practical engineering: MCP servers, RAG-based context tools, and smart coding harnesses that bring the right testing knowledge to the point of work. Outside of delivery, I contribute to open-source (including an npm-published RAG context engine) and write about flakiness, performance, and maintainable automation patterns.…I’m Anastasios Tilsizoglou, a Test Automation Architect and Principal Test Automation Engineer with 7+ years of experience designing automation frameworks and platforms used by entire QA organizations.

Senior Software Engineer in Test at Chubb

September 1, 2023 - Present

Designed an internal NPM automation framework adopted by 12+ engineering teams across 20+ projects, standardizing the QA approach and replacing duplicated/forked automation code. Served as the primary technical point of contact for QA automation architecture and test strategy, advising teams on framework structure and tooling choices. Deployed MCP servers and AI agent skills to make testing context retrievable at the point of work, standardized governed agentic AI coding harnesses across the organization, and helped rebuild CI/CD pipelines using open-source tooling to reduce licensing costs while maintaining delivery velocity. Built real-time quality dashboards for stakeholder visibility into test health and enabled data-driven prioritization.

Software Engineer in Test at Upstream Systems

September 1, 2022 - August 31, 2023

Integrated automated smoke and regression suites into daily CI/CD delivery cycles and developed custom test execution tooling to reduce manual overhead while expanding automation coverage for new product modules. Supported shift-left initiatives by feeding UX and performance findings back into design phases before development began.

Software Engineer in Test at Netcompany-Intrasoft

June 1, 2019 - September 30, 2022

Initiated the team’s first Jenkins CI pipelines for test automation, including scheduled overnight regression runs. Led code reviews as primary reviewer to keep automation aligned with consistent architectural standards. Authored traceability matrices and test artifacts to achieve 100% requirement coverage, and executed performance/load testing (LoadUI, Java) to identify and address system bottlenecks.
