CV

Hi! My name is Valentyn, and I'm a junior web developer with solid knowledge of Python, Java, and JavaScript. I’m constantly growing in both back-end and front-end development, focusing on clean code, clear architecture, and efficient problem-solving.

I’ve worked on several educational and non-commercial projects:

  • Developed the back-end for an online store (Spring Boot, JWT, PostgreSQL, REST API).

  • Created Telegram bots using Python.

  • Built responsive websites with HTML, CSS, and JavaScript.

  • Experienced with Git, Docker, CI/CD, SQL, and frameworks like Flask and Django.

I'm committed to delivering quality results on time. I pay attention to details, value feedback, and enjoy working in a team.
I love tackling unusual tasks, exploring new technologies, and improving my skills every day.

Open to collaboration and ready for exciting new projects!
