Here are some of the features that made it difficult to refine:

Improving the convenience of system users (awareness of participants about the current status in the competitive selection, a single entry point, information about all competition participants in one place), etc.

Features of the educational platform based on Knomary LMS
Before starting work, we conducted an audit of the system, which showed that it had a number of problems, without solving which the start of the project was in kuwait telegram number database question. Knomary is a ready-made solution with its shortcomings, but there is no way to clearly determine whether the problem is part of its code or something acquired during the contractors' modifications. From the code, we saw that many controversial decisions were made during the development of the platform's functionality, primarily due to the fact that the product did not provide for the ability to add additional structures. They were added along the way, with crutches and flaws, so that the system would work.

Outdated version of PHP and CodeIgniter — the framework underlying the LMS. The project is currently based on CodeIgniter version 3, it supports PHP 7.4 at most, which creates security risks and complicates support. Switching to the same framework version 4 will require a complete refactoring and partial rewriting of the code. If you do not neglect security, you need to upgrade to PHP 8.1, and this will require a change in the development approach.

Not very high quality of the system code. For example:

ignoring standard php functionality, for example here it is solved via ucfirst

code based on the principle ctrl+c & ctrl+v
