Available to start immediately. I build and fix real .NET & C# software. Click on Invite button to start conversation Iโ€™m a .NET Developer and C# Developer with 13+ years of experience working on production systems built in C#/.NET. Most of my work is focused on helping teams make their existing software more stable, scalable, and easier to evolve without risky rewrites. Iโ€™ve worked in long-term roles as a C#/.NET developer, often joining projects where the codebase already exists and needs structure, performance improvements, or careful modernization. ๐Ÿง  How clients usually come to me Very often, teams reach out to me as a .NET developer when they already have a product written in C#/.NET, but something isnโ€™t working as it should. Changes are slow, bugs appear in unexpected places, or the architecture feels fragile. In those cases, I step in as a C# .NET Developer who understands how real systems grow over time and how to improve them without breaking production. Depending on the scope, I work either as a backend developer focused on logic and performance, or as a .NET Full Stack Developer when both backend and UI decisions need to be handled together. โš™๏ธ What I do in real projects Day to day, my work as a .NET Developer is very practical. I write and refactor C#/.NET, clean up .NET architecture, improve async flows, and make sure the application behaves predictably in production. In many projects, this naturally turns into .NET full stack work handling backend services, APIs, and UI integration where I step in as a .NET Full Stack Developer. When teams want a modern .NET Full Stack direction without splitting the codebase, I build new features or full applications using .NET MAUI/WPF/WinForms. Iโ€™ve worked with .NET apps both for new products and for migrations from older stacks like, where stability matters more than speed. ๐Ÿงฉ Types of systems Iโ€™ve worked on Over the years, Iโ€™ve worked as a .NET Developer, across different environments: ๐Ÿ’ป Desktop software written in C#/.NET ๐ŸŒ Web platforms where I worked as a full stack developer on .NET backends ๐Ÿ“ฑ Cross-platform apps built with .NET MAUI (Windows & Android only) ๐Ÿงฑ Larger products that required a true full stack developer approach ๐Ÿ”— Mixed systems where .NET AI integration was part of the stack ๐ŸŽฎ Internal tools and simulators developed with C# ๐Ÿค– Careful use of .NET AI where it actually added value In several projects, I worked in React .NET setups, connecting React frontends to .NET backends while keeping responsibilities clean and clear. ๐Ÿ› ๏ธ How I work with teams and data Iโ€™m comfortable joining existing teams and reading unfamiliar C#/.NET codebases. I focus first on understanding why decisions were made, then improving things step by step. I regularly work with SQL server, collaborate with Azure Data Engineer roles, and support data-heavy systems where performance & reliability are critical. This mix of responsibilities often places me in a .NET Full Stack Developer role even when the original task starts as pure backend work. ๐Ÿ› ๏ธ Tech Stack .NET Framework, .NET 6 / 8 / 9 / 10 App Development - WPF, WinForms, WinUI, Blazor, .NET MAUI, MVVM Concurrency & Performance - Multithreading, async/await, Task Parallel Library Hardware & Protocols - Serial, Bluetooth LE, TCP/IP, UDP, RS232, RS422 Architecture & Quality - Clean Architecture, OOP, refactoring, performance tuning Security & Testing - Unit testing, Polaris, Coverity, SAST, DAST, threat modeling Data & Cloud - SQL Server, Azure Tooling - Visual Studio, VS Code, GitHub, GitHub Actions, Docker โœ… Why clients choose to work with me โœจ I think like a long-term .NET Developer, not a short-term task runner โœจ I write C# code that other C# developers can actually maintain โœจ Iโ€™m comfortable owning systems as a .NET Full Stack Developer โœจ I communicate clearly and avoid surprises โœจ I leave .NET full stack codebases cleaner and more stable than I found them ๐Ÿ“Œ Availability โœ… Available now ๐ŸŒ Remote-only โฑ๏ธ Open to long-term collaboration If youโ€™re looking for a .NET Developer, who can step into an existing system and improve it safely letโ€™s chat. ๐Ÿ‘‰ Send a message and weโ€™ll review your setup together.

How to Hire Top Windows App Developers

How to hire Windows app developers

Windows is the most popular operating system (OS) for personal computers. A Windows app developer can help you build software for platforms running Windows OS.

So how do you hire Windows app developers? What follows are some tips for finding top Windows app development consultants on Upwork.

How to shortlist Windows app development professionals

As youโ€™re browsing available Windows app development consultants, it can be helpful to develop a shortlist of the professionals you may want to interview. You can screen profiles on criteria such as:

  • Technology fit. You want a Windows app developer who understands the Microsoft technologies and third-party integrations needed to bring your software project to life. 
  • Project experience. Screen candidate profiles for specific skills and experience (e.g., leveraging WinUI to build a dash for your business intelligence app).
  • Feedback. Check reviews from past clients for glowing testimonials or red flags that can tell you what itโ€™s like to work with a particular Windows app developer.

How to write an effective Windows app development job post

With a clear picture of your ideal Windows app developer in mind, itโ€™s time to write that job post. Although you donโ€™t need a full job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if theyโ€™re the right fit for the project.

Job post title

Create a simple title that describes exactly what youโ€™re looking for. The idea is to target the keywords that your ideal candidate is likely to type into a job search bar to find your project. Here are some sample Windows app developer job post titles:

WINDOWS APP DEVELOPERS FAQ

Frequently asked questions

What is Windows app development?

Windows app development is the practice of developing software for Microsoftโ€™s Windows operating systems and devices. 

How much does it cost to hire a Windows app developer?

The first step to determining the cost to hire a Windows app developer will be to define your needs. Rates can vary due to many factors, including expertise and experience, location, and market conditions.

Cost factor #1: project scope

The first variable to consider when determining scope is the nature of the work that needs to be completed. Not all Windows app development projects are created equal. Creating a simple add-in for Outlook will typically take less time than developing a video game for Xbox One. 

Tip: The more accurately your job description describes the scope of your project, the easier it will be for talent to give you accurate cost estimates and proposals.

Cost factor #2: Windows app development experience

Choosing the right level of expertise for the job is closely tied to how well you determined the scope of your project. You wouldnโ€™t need an advanced Windows app developer to build a simple UI for your business app. On the other hand, developing an enterprise software-as-a-service (SaaS) app using Microsoft Azure and Windows AI will require more-specialized skills. Beyond experience level, you need to consider the type of experience the talent possesses. 

The following table breaks down the rates of the types of Windows app developer you can find on Upwork.

$60-90+

Expert

Seasoned programmer and professional who has the leadership and project experience needed to lead a team of developers in a Windows app development project.

$90-120+


 

Cost factor #3: location

Location is another variable that can impact a Windows app development cost. Itโ€™s no secret that you can leverage differences in purchasing power between countries to gain savings on talent. But itโ€™s also important to factor in hidden costs such as language barriers, time zones, and the logistics of managing a remote team. The real advantage to sourcing talent remotely on Upwork is the ability to scan a global talent pool for the best possible person for the job. Location is no longer an obstacle. 

Cost factor #4: independent contractor vs. agency

The final variable regarding talent cost is hiring an independent contractor vs. an agency. An agency is often a โ€œone size fits allโ€ model, so youโ€™ll often have access to a designer, a project manager, an engineer, and more. When hiring individuals you have total autonomy regarding who is responsible for which part of the project, but youโ€™ll need to source each of those skills separately.

The trade-off between hiring individuals vs. hiring an agency is the level of administrative overhead you incur personally in coordinating tasks among all members of the team. Project scope and personal preference will determine which style is a better fit for your needs.

Windows App Development Tips and Best Practices

Choose your UI development technology wisely

The user interface (UI) is the part of your app that the end user actually sees and interacts with. Itโ€™s the buttons, forms, search bar, content, layout, and other visual aspects of your app. The Windows app development ecosystem gives you many options for designing a UI. Here are some of the most popular:

  • UWP is short for Universal Windows Platform, which was designed to make it easier to build apps for any Windows device including computers, Xbox One, and HoloLens. Apps built with UWP are deployed through the Microsoft Store. 
  • WPF is short for Windows Presentation Foundation, a part of Visual Studio. WPF was designed for creating line-of-business apps for Windows. 
  • WinForms was around before UWP and WPF. Its drag-and-drop interface makes it easy to create apps with simple UIs, such as creating a graphical user interface (GUI) to allow non-developers in an organization to view business intelligence.
  • Electron is a framework for using web technologies (JavaScript, HTML, and CSS) to create a web view in desktop form, resulting in cross-platform desktop apps. 

These are just a handful of the libraries Microsoft provides for Windows app development. How you design the UI will ultimately determine the user experience (UX), so itโ€™s important to pick the right technology to design the front end of your app. 

Consider adopting a continuous integration and deployment (CI/CD) pipeline

CI/CD can save you serious headaches down the road if you can successfully implement it within your software development lifecycle (SDLC). The advantage to integrating your development and operations teams, also known as DevOps, through automation is not to be understated. With CI/CD tools such as Jenkins and Azure DevOps, itโ€™s possible to:

  • Ensure developers and testers are always working with the latest code repository
  • Make code compilation, error checking, and unit tests available at each step of the SDLC
  • Create installation packages you know will work on target platforms
  • Deploy your application and keep it up-to-date on your end usersโ€™ machines
  • Streamline the feedback loop of information between developers and operations

The above bullets are just some ideas of what CI/CD can do for an organization. There are plenty of DevOps tools out there to help you build a custom automation solution for your needs. 

Make software maintenance and troubleshooting easier with the right logger

Because desktop apps live on the machines of the end user (as opposed to cloud-based applications and websites), itโ€™s especially important to get error logging right. This will make it easier for your companyโ€™s IT and support staff to troubleshoot issues a user might encounter when using your project. 

Common logging solutions for Windows apps include:

  • Logging to file, which involves recording an event log to a file local to the machine using a library such as log4net or NLog. 
  • Saving dump files, which entails recording details of a crash (such as which process was executing and which modules were loaded) to a file local to the machine.
  • Logging to Windows event logs is fast and reliable; the only downside is that they can be difficult for your organization to retrieve. 
  • Remote error reporting, in addition to keeping local logs, gives the end user the option to send a report to your servers when a problem occurs so that your support team can log and process the issue. This can be a valuable tool for getting customer feedback integrated into your next patch. 

Logging is an important part of software development, and there are plenty of tools and libraries out there to help you do all of the above and more.
