Aleksa Elezović

I build all sorts of software, mostly full-stack web applications.

I graduated from a high school focused on programming and computer science. My studies covered mathematics, object-oriented programming (C#), databases (SQL), web development (HTML, JavaScript, CSS), logic programming (Prolog), and algorithms.

I started working in software development while continuing to learn through books and online courses.
