Thang Pham

Senior .NET Developer

I'm also familiar with responsive web design and third-party services like TFS, VSTS, SVN, and GIT.”

Representative of the team of .NET Developers dedicated for dot NET development services at Saigon Technology, Mr. Thang Pham also shares some other essential expertise:

Organizational skills

1. Organizational skills

Effective time management skills are crucial for.NET developers to complete their work on time. Even though perhaps the clients have set a deadline for receiving the final product, Developers can still actively keep track of their work and ensure that it gets done on schedule.

Resolution of issues

2. Resolution of issues

Many developers have the ability to solve an issue, but it is up to the developer to choose the best strategy for creating an answer that is both efficient and scalable. Being able to think critically and creatively about challenges is essential for developers, since it allows them to find alternatives and effective answers as they work.

Expertise in technology

3. Expertise in technology

A solid understanding of the.NET framework and any technologies built on top of it is essential for every .NET developer. Besides, he/she has to be familiar with WPF and MVVM practices for Windows desktop apps.

Coordination and communication

4. Coordination and communication

.NET developers often work alongside other engineers in the project to meet strict deadlines. Thus, .NET developers must be able to take into account the thoughts and experiences of their peers. They may effectively divide up work across team members.


5. Experience

This element is influenced by the significance and magnitude of the project, as well as the requested schedule from the client. On the other hand, three to four years of experience in.NET programming is the minimum amount of time needed to be considered an expert in the sector.


6. Databases

Microsoft SQL is the most common DBMS for .NET applications, but Oracle and MySQL are also widely utilized. Since.NET programmers often need to deal with massive amounts of data for their applications, a broad understanding of data science may be an additional valuable set of skills.

It is a framework for developing programs for the Windows operating system. It comes with a variety of built-in features that may be used to create, deploy, and execute web services and other applications. It's compatible with a wide variety of languages including C#, VB.Net, Cobol, Perl, and more.

Active Server Pages is the abbreviation for ASP. And the Common Language Runtime (CLR) is included with ASP.Net since it is part of the.Net framework. It's a free and open server-side technology that lets developers create robust websites, online apps, and web services.

The acronym CLS refers to the Common Language Specification. The CLS guidelines mandate that programmers utilize only cross-language compatible libraries and tools. Words and phrases that are compatible with the Internet.

The CLR-managed code is referred to as Managed code. The CLR hosts this code's execution. Consequently, the managed code cannot be run without the .NET framework being present. Any program that does not need the CLR to run is considered unmanaged. This indicates that it was created using a language other than those supported by Microsoft's .NET framework.

To keep an item in its current condition, State Management is necessary. The two main categories of State management are client-side and server-side.

- Storing data on the client's end, such as on a webpage. They are reusable, basic items.
- To store data on a server. Instead of relying on clients to save their state, it's more convenient to do it on the Server.

Caching is the process of temporarily storing memory data so that it may be accessed there rather than having to be retrieved from its original storage place. It improves the application's performance and efficiency.

- Caching comes in a few different flavors, including:
- Caching pages,
- Caching of data,
- Collection of fragments.

Similar to how a function reference works in languages like C and C++, a delegate is an essential part of the.NET framework. Using a delegate, the user may enclose the call to a method into a more manageable object.

Client-side validation is often performed in JavaScript. Client-side validation refers to the practice of doing validation in the user's browser, which is located on their local machine.
In the case of server-side validation, the validation is performed on the server itself. If a user manages to trick the client-side validation, we may still detect it in the server-side validation.
