About me:
I have a university degree in pedagogy. I have been working as a fitness trainer for 7 years, and all
this time I have been interested in computer programming, and I started learning programming more
than two years ago. At first, I learned HTML, CSS and everything related to them. After that, I
dived into learning JS.
After that I learned React and Redux and wrote my first web project, it was a small online store. I
also take part in various non-commercial projects to gain experience. And in parallel I study the
back-end part. I also read books on programming, such as “Clean Code”, “Refactoring”, “Grokking
Algorithms”. In back-end I study and practice NestJs, Express and worked with Mongo and
Postgresql databases.

Expirience:
My first project with Js, which was a very interesting project in a large team of budding
programmers, we worked together to develop a trading platform that was
focused on recycled products, eco products and handmade products. I was involved in the
development of both the back-end and front-end part. We used libraries like React on TS, Redux on
front-end. On back-end we used NestJS and MongoDB.
My first commercial experience was developing a web application for a gym. It was a lending web
application with the ability to register and view your own map and number of workouts.
My second commercial experience . We developed a sports app for a workout program and tracking
fitness results. I participated in the development of the front-end and back-end part of the app. Also
on the front-end we used React on TS and Redux. And in the back-end we used NestJS and
Postgresql.
I have about two years in full stack application development and one year of commercial full
stack development experience.
