I'm a junior front-end developer, with a bachelor's degree in mathematics and computer science.
I learned OOP, Data structure, Algorithms and many more topics in college. Although they were in c++ programming language. It helped me a lot understanding the basics of the world of programming.
Mathematics also has it's advantages when it comes to problem solving!
I use my HTML, CSS, JavaScript and node.js with express skills to help people build dynamic and responsive websites that serve their needs.
