The purpose of this project is to show the work developed during the business practices carried out between March 10th, 2021 until September 10th, 2021 in the company CertMind S.A.S. in the city of Bogota. The objective of the practice was to carry out the analysis, design, verification, testing, documentation and integration of the products of the QuizLab E-learning platform. In addition to this, the necessary supports corresponding to the user stories that were presented throughout the working day had to be made, which were transmitted by the immediate boss and uploaded in BitBucket in order to have greater control over the requests made.
