Hi! I’m Leopold.

Frontend Developer with 10+ years of experience in TypeScript, React, and cloud on Azure / AWS. One of my recent achievements is migrating the 'Track your item' application of Royal Mail from Angular to React, serving approximately 1.2 million users across the UK. I focus on building reliable user interfaces, contributing to major frontend migrations, and creating consistent, reusable UI components that are easy to maintain and update. My career path has been shaped by continuous learning and hands-on work building real products. I’ve grown steadily as a frontend developer, focusing on React and TypeScript, and getting better with each project I take on. I enjoy improving the things I work on, supporting teammates when I can, and creating smoother experiences for users. Furthermore, I am still developing my craft, but I’m proud of the progress I’ve made so far.

🚀 My personal motto: "Simplicity isn’t easy, but it’s worth it."
