In the next step, the project was migrated to a 3-layer architecture according to best practices. During development process 830 Unit Tests were created. During tests memory leakage was detected and resolved. As a result, test execution time was reduced by 11 times from 140s to 12s. The Docker image with all needed sample data was created to speed up development.2 project - Customer Calling System.A system where a manager can call customers and offer them a new product.Role - FullStack engineerTechnology - NodeJS, ExpressJS, Babel, WebPack, React 15 and 18 with hooks, Redux, AntDesign.2 Frontend parts of this application was migrated from React 15 class components with Grommet UI to React 18 hooks with AntDesign UI. ~95% of codebase were refactored. Backend part was migrated from NodeJS version 8 to version 16 - all libraries were updated to latest versions and some code was refactored according to new versions of libraries.3 project - Orders Management System.A system where manager can collect all items from online order into one box and send it to customer via one of delivery providers.

Mobile application Nucash was written with React Native and TypeScript. When the number of screens increased and the interaction between components became more complex, I introduced the Redux state manager into the project. As a result, 72 files were refactored and the interaction between components was simplified.
