My experience included developing components, modules, services, and pipes for managing data and visualizing information about wells. I also worked with libraries such as D3.js, ECharts, for creating charts and diagrams.One of the most important aspects of my work was ensuring high application performance and optimizing server requests. To achieve this, I used techniques such as data caching, lazy loading, and asynchronous loading.In addition, I communicated with the client regarding their business requirements, created code guides for developers, and prepared client documentation. I also worked with legacy code, which I maintained and rewrote to new standards, as well as fixed bugs.I worked with other team members to ensure data security and protection, as well as to develop user authentication and authorization functionality. All metrics and information about oil and gas wells were provided through the API server, which I integrated into the application.Tech stack:- Angular, React, NgRx, TypeScript, JavaScript, SCSS, Webpack, ECharts, D3.js, PrimeNG, Python, PostgreSQL, MobX, FireBase
