First project: I was responsible for front-end development. There was Angular with NGSX. Also, I implemented a few features on the backend. There were several microservices in NestJS.Second project: I am a full stack developer. There is React + Redux + Thunk on the frontend. Also, there are a few microservices with Spring Boot and several microservices with .NET. But I am only responsible for Spring Boot applications.

I was responsible for implementing features on the front-end (Angular) and on the back-end (PHP and Oracle databases). There was legacy code that was hard to maintain. I learned how to implement features between crutches. Also, I was responsible for finishing and maintaining a tool. It was on Spring Boot (Spring Statemachine, Messaging).

I had a huge spectrum of responsibility. Begins with setting up a server. Ends implementing features. While I worked, I implemented many features and made several integrations between internal and external systems. Here is the list of technologies I used: ReactJS (redux, redux-observable), Angular, PHP, NodeJS, MySQLHere are a few features I implemented:I made integrations between PBX and CRM. When a manager has an incoming call, he can see who is calling and their history with the customer. After the conversation, he will write a summary in the application. And when the customer calls next time, the manager will see the summary, and he will restore context very quickly.I implemented an estimate calculator. A manager or a customer can answer questions in the application and get an estimate with a proper count of materials, volume of work, and delivery fee. The system calculates the volume of materials and then calculates the minimum count of proper containers. I also developed a formula for calculating labour costs depending on the amount of work.
