About me
I create modern web applications with a passion for clean code and effective solutions. I continuously develop my programming knowledge through practical projects and systematic learning of various methodologies and programming languages. My main area of interest is developing software primarily in back-end domains, where I can combine my technical and analytical skills. I've been interested in programming since technical school, and recently I've also become interested in software architecture.
