Automated Software Tests Development
Category : Testing and QA
I am a QA/Test Automation Engineer and delivery-system builder with over 20 years of experience in software development and automation across finance, education, and cooperative sectors.

My expertise includes test automation (Playwright, Cypress, Python), CI/CD pipeline design with GitHub Actions, and building reproducible delivery systems that make work visible, reduce rework, and raise release confidence. I also have extensive experience in Python, TypeScript, C#, SQL, and ASP.NET, with a strong foundation in modern web frameworks such as React, Next.js, and WordPress.

I help my clients achieve consistent, high-quality releases by establishing automated testing practices, standardizing branching and review workflows, and implementing PR gates and static analysis to prevent regressions. My approach emphasizes spec fidelity through automated validation, enabling safe, low-stress refactoring and continuous improvement.

Whether building E2E testing platforms, automating reporting pipelines, or leading website renewals, I deliver robust, maintainable solutions that align engineering precision with real business needs—allowing teams to focus on innovation and sustainable growth.
