Hello! I'm Kasia Rosińska
a front-end developer with two years of experience. I enjoy building websites & apps. My focus is React, Next.js and JavaScript.

Scroll down to explore a showcase of my projects and learn more about my professional journey.

About me

After graduating with a Master's degree in Economics and working as an Accountant for a few years, I decided to follow my curiosity about programming. I enrolled in a coding bootcamp where I learned front-end development and earned the title of JavaScript Developer along with a certificate.

Before I started learning HTML, CSS, and JavaScript I thought of programming as a kind of magic, but as I studied it, I realized it’s a fascinating, methodical and enjoyable thing to do. Now, I can't even imagine coding not being a part of my daily life.

My favorite aspect of programming is planning and breaking down tasks into smaller, manageable parts. I love the satisfaction of solving problems and seeing everything I planned come together and work as intended. I primarily work with React, and use TypeScript daily. I am continuously learning and gradually implementing new tools and technologies, such as Next.js and Tailwind CSS, MUI into my projects. Collaboration, clear communication, and a user-first mindset are at the core of my professional approach.

When I'm not coding, I like reading travel books and articles about Japan, watching movies, and cooking Asian food. I am currently learning to meditate. I also really love traveling, planning new trips, and meeting new people.
