Have you worked with integrations, application development, backend, frontend?

Yes, I have experience working with integrations of various systems through REST API and SOAP, which included developing backend services for request processing and interaction with external services. I also participated in creating frontend applications using React and Vue.js, ensuring a user-friendly interface. In backend development, I used Node.js and Python to create APIs and business logic, as well as worked with databases and message queues to ensure reliability and scalability.
