I believe AI is changing how we write software, but it shouldn't change how we validate it.
Throughout my career I've focused on one question: how can we help engineers build reliable software with confidence?

That question has shaped everything I've done, from teaching JavaScript and testing for more than six years, to mentoring engineers, leading frontend teams, speaking at internal and community events, and creating open-source tools that improve the development experience.

Today I'm a Software Architect, where I help engineering teams improve software quality through testing strategies, developer experience, and responsible AI adoption. Rather than treating tests as something we write after the code, I believe they should become the foundation that allows both developers and AI coding assistants to move faster without sacrificing quality.

This philosophy led me to create TWD (Testing While Developing), an open-source methodology that brings testing directly into the browser, turning tests into executable documentation and enabling rapid feedback during development.

One of the parts of my job I enjoy the most is helping other engineers grow. Whether I'm mentoring junior and mid-level developers, interviewing candidates, leading workshops, or speaking at meetups and podcasts, I enjoy sharing knowledge and creating environments where people can become better engineers.

My main interests are software quality, testing, accessibility, developer experience, AI-assisted development, and engineering education.
