About
I’m Andrii Horbach, a Senior QA Engineer with 14+ years of experience testing complex, data-intensive, transaction-driven systems across fintech, cloud, healthcare, logistics, and enterprise software. I focus on end-to-end quality—manual, API, backend, integration, regression, and data validation—working across the full stack from UI and mobile apps to services, databases, and data pipelines.
I’m especially strong in QA for financial workflows, ETL/ELT verification, data integrity and reconciliation, and large-scale migrations. I build and improve automation frameworks using Java, Selenium, Playwright, and TypeScript, and I run CI/CD-driven execution through tools like Jenkins, Git, and Maven to improve coverage and reduce regression cycles. I enjoy owning test strategy as QA lead, structuring coverage under delivery constraints, and collaborating with stakeholders to ensure reliable releases.
