ABOUT ME

I build products and
help teams level up.

I'm a Senior Software Engineer with over 15 years of experience in software development, including more than nine years building enterprise React applications. Throughout my career I've worked across frontend engineering, quality assurance and automation, giving me a well-rounded understanding of the entire software development lifecycle.

I enjoy building clean, maintainable user interfaces that solve real problems. Whether I'm developing reusable React components, integrating GraphQL APIs, improving application performance or collaborating with designers and product managers, my focus is always on delivering software that's intuitive, scalable and easy to maintain.

Having started my career in quality assurance, I developed a strong appreciation for testing, reliability and attention to detail. That foundation continues to influence how I approach frontend development today—from writing automated tests and reviewing code to mentoring other engineers and promoting engineering best practices.
