1) have experience in mentoring team members
- I trained interns, and I led a group of six interns to do a final project and taught them to work in a team and in an enterprise environment. As a result, they created a successful project and were hired by the company
- have experience in interviewing/mentoring people
- In several companies taught people about testing
- on my last job I was working as an architect and managed up to two projects at the same time, mentoring 2 teams and participating in the development

2) like best practices and like moving the team towards it - CI/CD, code styles, testing (unit, e2e)
- I have experience in several different teams where I was setting up testing frameworks, making mentorship over the team to help everyone get used to writing tests.

3) have experience in moving an old application to a newer stack
- for example, I moved a highly loaded PHP site to Next.js. We moved the site part by part, continuously enhancing it. As a result, the new application got 100 of 100 in LightHouse (was 40), increased significantly SEO positions and made much better-optimised performance.
- organized process of moving the core application of the company that was written in a bad way. Now we can see improvement in usability and performance. Also, time for development was reduced because of the straightforward architecture of the application. Improved amount of bug in production.

4) I have a lot of experience with improving performance and refactoring.
- I have improved size and load time for a widget for 60% by refactoring the code and using the right solutions.
- Resolved issues with scrolling and gestures on one of the sites, so it feels much more user friendly.

and much more ;)
