Jan Chalupa portfolio | About me

Hi, I’m a Senior Full-stack Developer and Junior iOS Developer, passionate about building user-friendly applications. I started programming in 2008, experimenting with HTML, CSS, JavaScript, and C#, which led me to develop interactive websites and Windows Phone apps.

Over the years, I specialized in React and Next.js, building projects for multiple companies. Recently, I’ve shifted my focus to Swift and SwiftUI to develop iOS apps, aligning my work with the Apple ecosystem I use daily.

Beyond coding, I enjoy playing guitar and bouldering, combining technical expertise with creativity.
