# About me

Hi again! I'm Oskar, an experienced Frontend Developer from Poland 🇵🇱. I have been working in the industry for 6 years and I'm always looking for new challenges and opportunities to grow. On a daily basis I build complex applications simple things, mostly moving rectangles and pixels from one place to another. Since my teenage years, I have been building things from scratch, and initially, most of them were aimed at simplifying life for myself and the people around me. Over time, it became my job, and now I enjoy it every day. By the way, I still haven't told you, I love working with Vue.js , Tailwind CSS , and TypeScript .

# Education

You might notice that my studies are not in computer science. As a self-taught developer, I find it easier to learn technical skills independently. I chose to study management because I believe a broad understanding of business benefits my clients. After all, the code I write directly impacts their businesses. This combination of technical skills and business knowledge allows me to create more effective solutions for my clients.
