I am a game programmer who is most proficient in Systems, Tools, and Networking. However, I enjoy all areas of Game Programming and I am very passionate about exploring new areas. It is often a goal of mine to make development easier for all team members, whether that means making tools for non-programmers or implementing robust modular frameworks for other programmers. I am passionate about taking on new challenges and supporting my team members. I have the most experience in Unity / C#, but I am also well acquainted with Unreal and C++. I have worked on both solo and collaborative projects. I have strong communication skills, and I have received lots of positive feedback, both for my programming work and the feedback I give the team. I am very passionate about making games, especially ones that bring people together and ones that intend to have a strong emotional impact. When I am not programming, I like to cross-stitch, make pixel art, and play board games and videogames. My favorite genres are probably roguelites and platformers, but I have games that I love in almost every genre I can think of.

Available to start immediately. I build and fix real .NET & C# software. Click on Invite button to start conversation I’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. I’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. 🧠 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 isn’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. ⚙️ 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. I’ve worked with .NET apps both for new products and for migrations from older stacks like, where stability matters more than speed. 🧩 Types of systems I’ve worked on Over the years, I’ve worked as a .NET Developer, across different environments: 💻 Desktop software written in C#/.NET 🌐 Web platforms where I worked as a full stack developer on .NET backends 📱 Cross-platform apps built with .NET MAUI (Windows & Android only) 🧱 Larger products that required a true full stack developer approach 🔗 Mixed systems where .NET AI integration was part of the stack 🎮 Internal tools and simulators developed with C# 🤖 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. 🛠️ How I work with teams and data I’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. 🛠️ 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 ✅ Why clients choose to work with me ✨ I think like a long-term .NET Developer, not a short-term task runner ✨ I write C# code that other C# developers can actually maintain ✨ I’m comfortable owning systems as a .NET Full Stack Developer ✨ I communicate clearly and avoid surprises ✨ I leave .NET full stack codebases cleaner and more stable than I found them 📌 Availability ✅ Available now 🌍 Remote-only ⏱️ Open to long-term collaboration If you’re looking for a .NET Developer, who can step into an existing system and improve it safely let’s chat. 👉 Send a message and we’ll review your setup together.

C# Developer Hiring FAQs

What is a C# developer?

C# developers write quality code for responsive desktop and web applications or back-end processes. C# is an adaptable, object-oriented programming (OOP) language based on the Common Language Infrastructure.

How do you hire a C# developer?

You can source C# developer talent on Upwork by following these three steps:

  • Write a project description. You’ll want to determine your scope of work and the skills and requirements you are looking for in a C# developer.
  • Post it on Upwork. Once you’ve written a project description, post it to Upwork. Simply follow the prompts to help you input the information you collected to scope out your project.
  • Shortlist and interview C# developer. Once the proposals start coming in, create a shortlist of the professionals you want to interview. 

Of these three steps, your project description is where you will determine your scope of work and the specific type of C# developer you need to complete your project.

How much does it cost to hire a C# developer?

Rates can vary due to many factors, including expertise and experience, location, and market conditions.

  • An experienced C# developer may command higher fees but also work faster, have more-specialized areas of expertise, and deliver higher-quality work.
  • A contractor who is still in the process of building a client base may price their C# developer services more competitively. 

Rates typically charged by C# developers on Upwork are:

  • Beginner: $25 per hour
  • Intermediate: $47 per hour
  • Advanced: $120 per hour

Which one is right for you will depend on the specifics of your project. 

How do you write a C# developer job post?

Your job post is your chance to describe your project scope, budget, and talent needs. Although you don’t need a full job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if they’re the right fit for the project.

Job post title

Create a simple title that describes exactly what you’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 C# developer job post titles:

  • C# developer needed for macroverse engineering support
  • Seeking C# developer for an educational game
  • Looking for a C# developer for a real estate app

Project description

An effective C# developer job post should include: 

  • Scope of work: From configuration to execution, list all the deliverables you’ll need. 
  • Project length: Your job post should indicate whether this is a smaller or larger project. 
  • Background: If you prefer experience with certain industries, software, or architectural patterns, mention this here. 
  • Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.

C# developer job responsibilities

Here are some examples of C# developer job responsibilities:

  • Take an application storyboard from concept to reality
  • Outline, write, and maintain functional, responsive, and reliable C# code
  • Plan and build user interfaces and interactive media applications
  • Identify and fix bugs and bottlenecks

C# developer job requirements and qualifications

Be sure to include any requirements and qualifications you’re looking for in a C# developer. Here are some examples:

  • Experience working in various C# ecosystems and using OOP
  • Background in building RESTful web services with WCF/WebAPI
  • Familiar with an array of architectural and design practices
  • History of supporting business processes with clean C# code and database schemas
