Summary

I'm a Full Stack Developer with over 7 years of experience. I have developed several cross-platform mobile applications using React Native, as well as multiple Full Stack web applications using React and Node.js.

While I am capable of building full-stack applications, my true passion lies in the frontend part of development. I find working with graphical interfaces very satisfying, particularly in making them more user-friendly. To that end, I have completed several courses in UX and continue to expand my knowledge in this field.
