Data Engineers implement methods to improve data reliability and quality. They combine raw information from different sources to create consistent and machine-readable formats. They also develop and test architectures that enable data extraction and transformation for predictive or prescriptive modeling, and loading of data from a wide variety of data sources using SQL and AWS ‘big data’ technologies.
They put architecture models into production and build the infrastructure required for optimal extraction, and transformation. Choosing optimal solutions to use for collection, storing, processing, and analyzing huge sets of data, then maintaining, implementing, and monitoring them. The DD is also responsible for integrating them with the architecture used across the company.
Backend developers build code that allows a database and an application to communicate with one another. Backend developers take care of and maintain the back end of a website, including databases, servers, and apps, and they control what you don’t see.
Node.js developers deploy and maintain network applications. They manage the exchange of data between servers and users, develop back-end components, and connect applications with other web services. They also support front-end developers by integrating web-based applications.
A Front-End Developer is responsible for developing new user-facing features, determining the structure and design of web pages, building reusable codes, optimizing page loading times, and using a variety of markup languages to create the web pages.
