On the JavaScript side, we work with technologies such as JavaScript, TypeScript, React, Next.js, Redux, Node.js, Nest.js, Express, TypeORM, and Sequelize, depending on what the product actually needs.

XcelTec handles custom web and server apps, Node.js development, ReactJS development, Vue.js development, and JavaScript customization. Their service scope is broad, so a business can use them for a smaller front-end task or a fuller web application that needs server-side logic, responsive screens, and ongoing adjustments after launch.
