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.

Most founders spend months waiting on developers then get a half-built product that costs more than planned and still isn't ready for real users. I solve that. I'm an AI MVP Developer specializing in rapid SaaS prototyping, no-code web application development, AI integration, and workflow automation. Using Lovable, Base44, Supabase, and Cursor, I help startups, SaaS founders, and businesses go from raw idea to fully working product faster and cheaper than traditional development ever could. WHAT I BUILD FOR YOU SaaS MVPs and Web Applications I build minimum viable products from the ground up lean, functional, and ready for real users. Every MVP is scoped to prove your core value proposition fast so you can attract investors, gather feedback, and generate revenue without wasting months in development. Admin Dashboards and Internal Tools I build custom dashboards and internal tools that give your team real visibility and efficiency user management panels, operational dashboards, and client-facing portals that your team will actually use every day. Micro-SaaS Products Focused, single-purpose software solving one specific problem for a specific audience. I build micro-SaaS products that launch fast, monetize cleanly, and grow without constant developer involvement. AI-Integrated Applications I integrate AI capabilities directly into your application whether that's an AI-powered feature, an intelligent workflow built around a language model, or a fully AI-native product built from scratch. Workflow Automation and API Integrations Manual processes kill productivity. I build automation systems using n8n and AI-powered pipelines that eliminate repetitive work, connect your tools through smart API integrations, and keep your business running without manual intervention. HOW I WORK I use an AI-assisted, vibe coding development approach combining the most powerful modern no-code and AI-native platforms to ship production-ready applications at a speed traditional development cannot match. Lovable Full-stack web apps built fast. Production-grade interfaces connected to real back-end logic, deployed quickly and built to last. Base44 An AI-native platform for rapid full-stack application generation. Few freelancers on Upwork work seriously with Base44 this is a real competitive advantage for your project. Supabase Scalable database management, authentication, and real-time back-end infrastructure. Clean, secure, and ready to grow with your users. Cursor AI-powered coding for precise custom logic when no-code platforms reach their limits. Speed of AI development plus accuracy of custom code. WHO I WORK BEST WITH — Startup founders validating a SaaS idea without a technical co-founder — Entrepreneurs who need an MVP built fast to attract investors or early users — Non-technical founders who need a clear, communicative technical partner — Small businesses needing dashboards or automation without enterprise budgets — Product owners adding AI integration to an existing workflow or application WHY CLIENTS CHOOSE ME Speed without sacrificing quality. Your runway is limited, your timeline is real, and your product needs to work not just look good in a demo. I build fast and I build right. I think like a product person. I don't just execute instructions I think about what you're trying to achieve, flag what doesn't make sense, and help you make smarter decisions throughout the build. Clear communication. No going silent. No unexpected deliveries. Regular updates, right questions asked upfront, and full alignment at every stage. Honest timelines. I won't promise three days if it takes two weeks. I scope honestly and deliver on my commitments every time. LET'S BUILD SOMETHING If you need a SaaS MVP, web application, admin dashboard, micro SaaS product, workflow automation system, or AI integration built fast, built clean, by someone who understands what you're actually trying to build send me a message. Tell me what you're working on. I'll respond quickly and give you honest feedback on how I can help. The fastest path to your product starts with one conversation.

If your business has outgrown packaged software, I build what fits — custom, end-to-end solutions designed around your exact processes. Since 2006, I've delivered bespoke software across 8+ countries for clients ranging from global enterprises to funded startups. I currently maintain active support contracts with Vodafone and Philip Morris International, and have built and shipped products in logistics, fintech, agriculture, manufacturing, real estate, maritime, and SaaS. What I bring that most developers don't: — I've sat inside IT departments of large corporations, so I understand how decisions are actually made and what "production-ready" really means. — I've founded multiple software ventures of my own, so I understand the pressure of building something that has to work from day one. — I work across the full stack: mobile (Expo / React Native), web, desktop, backend APIs, cloud infrastructure (Azure, AWS), databases (MSSQL, Supabase, PostgreSQL), and third-party integrations (Stripe, open banking, ERP systems, barcode/IoT, and more). — I own physical iOS, Android, macOS, and Windows devices — every build is tested on real hardware. I work in structured weekly milestones with written updates, clear communication, and no surprises. My clients stay with me long-term because the work is done properly the first time. If you have a project that needs to be built right — not just built fast — I'd like to hear about it.
