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. .NET Stack | .NET Core | .NET Framework | ML.NET | Machine learning | AI Developer | Ubuntu | Linux | Windows Subsystem for Linux | PowerShell | Bash | Python | C# | C++ | C | Azure | ASP.NET | ASP.NET Core | MVC | Semantic Kernel for .NET | OpenAI & Azure OpenAI | RAG & Vector Search (Azure AI Search, pgvector) | Blazor Server | Minimal API | Web API | Angular | Entity Framework Core | SQL Server | PostgreSQL | CI/CD | GitHub Actions | Blazor WASM | SOLID principles | REST APIs | React Native | Kotlin | Embedded Systems | Claude Code | Codex | AI Engineer
