Backend Web Development

The challenge

Develop new functionalities on a legacy system, contributing from innovation but adjusting to the scheme proposed by the client. We had to implement a new secure document submission scheme for public works bidding, in which suppliers must register in an existing system. Then we had to allow the safe download and upload of files for the presentation of quotes. On the other hand, we had to generate restricted viewing for personnel who analyze supplier info and quotations.

The solution

We implement a custom design provided by the client in HTML5 & CSS3 above Php Laravel for the backend support. We developed a secure functionality using JavaScript for the upload, view and download the files of suppliers.

We divide the project into two-week sprints and meet the deliverables in a timely manner.
