I’m Winston Castillo, a passionate expert in quality assurance and technology, with over 18 years of experience in software testing and process optimization. As the author of Shift Left Testing in a Few Pages, I’ve had the opportunity to share my knowledge and experiences with a community committed to learning and continuous improvement in the world of technology.

My journey began at the Venezuelan Institute for Scientific Research, where I discovered my passion for quality. After my experience in Venezuela, I moved to Ecuador, where I spent over five years in a company that left a significant mark on my life and contributed greatly to my professional growth. All of that learning is now reflected in my book, articles, and courses available on platforms like Udemy.

I enjoy creating content that blends humor and teaching, making complex concepts accessible to new professionals and experts alike. Through my social media channels, I share tips, practical advice, and stories that inspire testers and developers across Latin America.
