Project - Knowledge System

An educational system which allows for creation of study materials and tests for users to study with. Also with user study time and activity tracking. It is an Asp.Net Core Angular single page application with a WPF Companion app. Project is using Clean Code and SOLID approaches with continuous integration and unit, integration and end to end tests.

Backend is using Controller-Service-Repository approach, all the business logic is in small services. Code quality is very important on this project, SonarQube is used to control the quality.

A sophisticated Metadata subsystem based on conventions, custom attributes and reflection is implemented to reduce the amount of code for CRUD operations.

Technologies used: .Net Core, Asp.Net Core, SignalR, Entity Framework, PostgreSql, SqlLite, Ms Sql Server, Angular 8, Angular Material, Asp.Net Core Identity, Selenium WebDriver, Protractor, Karma, SonarQube.

Notable contributions:

• A big part of this project was to implement generic metadata approach for testing, so I took part in developing a subsystem which would automatically tests entities based on metadata

• Developed a standalone Companion app for the websystem:

1. Added ability to launch and manage an FFmpeg video codec process for screen video recording
   
2. Added SignalR communication
   
3. Added synchronization of data to the main web system with retries
   
4. Implemented background jobs in the app
   
5. Added SqlLite storage
   
6. Added keyboard and mouse usage masked analytics
   

• Wrote integration and end to end tests for web system and Companion

• Introduced Css Bem into the project

• Extended meta subsystem

• Extended client side validation functionality

• And many others

Many diverse web and IOS applications. I was involved in writing test cases and making bug reports. I did Functional, UI and Exploratory testing.
