About Jakub Jirák

Senior Test Manager · Test Automation & QA Expert

Who I Am

Hi, I'm Jakub Jirák — a Senior Test Manager and QA expert helping organizations design scalable testing frameworks, integrate QA into DevOps pipelines, and drive innovation through modern testing practices. With over 10 years of enterprise experience, I've trained 10,000+ professionals and automated over 1,000,000 tests across diverse industries.

I'm also the author of 4 published books, including the award-winning Think Different: How AI and Automation Are Changing Software Development, and a JetBrains plugin developer building professional IDE tools for testing, accessibility, and security analysis. I also founded HTJ2K MetaWave, the world's fastest JPEG 2000 codec optimized for Apple Silicon.

About This Blog

Think Different is where I share practical insights, tutorials, and deep dives into the topics I work with every day — from AI-powered development workflows and test automation strategies to performance optimization and modern QA practices.

I don't just write about technologies — I use them in production, test them thoroughly, and share what actually works. My background in quality assurance and performance engineering means I approach every topic with a critical eye, verifying claims and testing edge cases before publishing.
