What skills and knowledge have you gained during your professional career?

During my professional activity with C#, I acquired skills:

• Deep understanding of object-oriented programming (OOP): classes, inheritance, polymorphism, encapsulation.
• Working with collections and LINQ for convenient data processing.
• Asynchronous programming with async/await to improve application performance.
• Using .NET Framework and .NET Core to create console, web, and desktop applications.
• Experience working with Entity Framework for database interaction.
• Understanding of SOLID principles and design patterns for writing maintainable and extendable code.

Example of a simple asynchronous method in C#:

public async Task<string> GetDataAsync()
{
    using HttpClient client = new HttpClient();
    string result = await client.GetStringAsync("https://example.com/api/data");
    return result;
}
