What was your experience participating in previous projects and how long did you work on them?

Experience in projects typically includes descriptions of roles, tasks, and duration of work. For example, I worked on an e-commerce application for 6 months, where I was involved in developing the user interface and integrating with the backend.

In another project — a mobile fitness app — I was responsible for implementing activity tracking functionality and optimizing performance, working on it for about a year.

It is important to specify the technologies, tasks, and results to demonstrate your contribution and experience.
