Express JS is a web application framework that aids in the development of both single and multiple web applications.

Businesses require web applications to run business operations. A well-developed Express JS application requires a programmer who has extensive programming background, using specialized programming frameworks with many robust features. As a business owner, you need not understand technical programming behind the development of a web application. This does not prevent you from benefiting from the work the application will help you achieve. For this to be possible, you will need the services of an Express JS specialist to handle the programming for you while you focus your attention on what you understand better. This is where Freelancer.com comes in handy.

Experts in the use of Express JS frame understand the ins and outs of the frame. With your level of experience and expertise, you should be able to demonstrate to the clients that they can rely on your knowledge in handling their projects. Your profile should represent what you can offer. As the role depends solely on your competencies, it is easy to handle different clients at the same time and keep delivering quality service. As a freelancer, you will never be out of work.

    Looking for NodeJs Engineer to accomplish the following task. Add Swagger to existing API, so we only need to interact with GUI to hit the route and see all responses. Clean up and centralize error handling so it does not fail running the application. Currently, we have an unused error handler we want to use for general error catching. This will mean catching DB errors and AWS errors as well. We have a couple of routes that are making multiple calls to the DB. We want to wrap these calls in a single transaction, so if one fails we rollback the DB. We're also storing images in AWS. We want to first determine if an image is a duplicate and then overwrite if it is. Add a remove image route, that removes the specified image from AWS. It is not MySQL, it's actually PGSql, they ...
