Tell about a time when you saw an inefficient process in a company — what did you do to change it?

In one company, I noticed that the process of building and testing a Flutter application took too much time due to lack of automation and code reuse. Instead of each developer manually running tests and building the app, I proposed implementing CI/CD with automatic testing and building on each commit. I also extracted common widgets and logic into separate packages to avoid duplication and simplify maintenance. As a result, build and test times were halved, and code quality improved through unified standards and automatic checks.
