– For the last three years, I have been responsible for creating and refining a “starter project kit” for our team, which has drastically reduced the time required to release new products, from a year for the first product to three months for the latest (≈x4 to productivity). This kit includes SSR implementation, declarative routing and business logic, web-vitals performance improvements, JWT authorization, unified styling, and a wide range of React components integrated with other services. – As such, our team has adopted the best Scrum practices. Work in close cooperation with various teams, including UI/UX, stakeholders, and product owners.– The company's main technology stack consisted of React, Node.js/Express.js, Redux, Styled-Components, Jest, Docker, and GitLab CI/CD. Furthermore, we have developed several add-ons for Redux called ReducerBuilder and EpicBuilder. These add-ons utilize reactive and functional programming solutions (such as lodash, Rx.js) to create business logic in a declarative style.
