I'm a Full Stack Developer and .NET Developer with 10+ years building web applications that businesses actually run on. I take an idea and ship it — front end, back end, database, deployment — and I've done it for products still serving customers a decade later. ✦ WHAT I DO BEST My core stack is .NET and C#. As a .NET Developer I build secure, scalable back ends with .NET Core and ASP.NET Core, expose them as clean ASP.NET Web APIs (REST), and back them with Entity Framework and SQL Server, PostgreSQL. As a Full Stack Developer I pair those APIs with responsive front ends in Angular, React, or Blazor, then deploy and scale on Azure with Azure DevOps, Docker, and CI/CD. When a product needs AI, I wire proven models — often through a thin Python layer — into the application without breaking what already works. And when a templated WordPress or Shopify build has hit its ceiling, teams bring me in to rebuild it as a custom .NET web application that can actually grow. ✦ PROOF OF WORK Longevity is the point. I once took a rough idea from an automotive client and built it into an e-commerce platform that has served customers for nearly 15 years and still runs today. As the lead .NET Developer on Launch Control, a real-estate SaaS, I refactored the core and made the system 50x faster. I also built SiftScore, an AI-powered talent-acquisition platform that uses the OpenAI API to source and score large datasets. Across fintech, real-estate, and healthcare I've owned the full lifecycle as a Full Stack Developer: requirements, architecture, build, go-live. 🚀 SaaS MVP (From Idea → Production) When a client starts from a rough idea, I take it the full way: requirements, architecture, prototyping, build, and go-live on Azure. As a Full Stack Developer I've shipped .NET SaaS MVPs for fintech, real-estate, and conveyancing platforms — clean, maintainable code with the scalability and monitoring to grow once real customers arrive. ✦ AI Integration for Existing Products I add AI features when a product actually needs them. The fastest, most cost-efficient path is usually integrating a proven model — OpenAI, Claude, or Gemini, often through a thin Python layer — rather than training your own. I add chatbots, automation, and smart search to existing web apps. Most AI features fail not because of the model but because the surrounding .NET architecture wasn't built to support it — and that's where a senior Full Stack Developer earns their keep. ⚙️ Modernizing Existing .NET Systems - without the rewrite If you have a .NET or C# application that needs work, I optimize performance, refactor legacy code, upgrade aging ASP.NET back ends, and migrate data access to Entity Framework Core — refactored against SOLID principles, without freezing feature work. Stuck on an old ASP.NET WebForms app? You don't have to gamble on a big-bang rewrite. As a .NET Developer I migrated a WebForms spare-parts store — 20M+ products across 100+ suppliers — to ASP.NET MVC by running both side by side in one solution, so the business kept selling while the modernization happened underneath it. The same incremental approach moves teams off PHP, Laravel, or legacy WordPress builds and onto a maintainable .NET stack: ship value continuously, retire old code gradually, never go dark. ✦ Legacy .NET project modernization Old code isn't the enemy — downtime is. As a .NET Developer, I modernize legacy ASP.NET and ASP.NET MVC systems by introducing a clean API layer, migrating data access to Entity Framework Core, and refactoring against SOLID principles, all without freezing feature work. As a Full Stack Developer, I migrate the application page by page behind a feature flag, so new and old run together in production and you can switch any screen over — or roll it back instantly — without disrupting users. Whether it's an ASP.NET MVC application that has grown brittle or a WebForms system that needs a path forward, I find the route that lowers risk: incremental, tested, and reversible at every step. ✦ ENTERPRISE-GRADE .NET ARCHITECTURE My work as a Full Stack Developer goes deeper than features. On a large enterprise fintech platform built on microservices, as a Full Stack Developer I designed how the team builds — onboarding developers, setting architectural standards, and structuring a clean, maintainable .NET codebase that scales. As a .NET Developer with a decade across .NET Framework, .NET Core, ASP.NET, and ASP.NET MVC, plus an M.Sc. in Applied Mathematics behind the design decisions, means I build systems meant to last years, not quarters. I focus on web rather than native mobile apps in Flutter or React Native; on the .NET side I also ship cross-platform with .NET MAUI. I'm a web developer — my C# and .NET expertise powers web applications. ✦ HOW WE'LL WORK If you need a Full Stack Developer or .NET Developer who can take something from rough idea to production — and keep it running for years — let's talk about the fastest path to shipping it.

I build custom C# / .NET software for businesses that need reliable desktop applications, internal tools, and practical workflow solutions. My main experience is in Windows desktop development and business software. I work with C#, WPF, MAUI, ASP.NET Core, Razor, MVC, MVVM, SQL, Entity Framework, and Web API, and I’m also interested in Blazor-based internal applications. I’m a good fit for projects involving internal tools, workflow systems, document generation, printing features, integrations, and software that supports day-to-day operations. I work well on MVPs, prototypes, and milestone-based projects where the goal is to turn a business need into a practical working solution. I can take ownership of a project, communicate clearly, and make practical decisions to keep development moving. I can also help refine requirements as the project evolves. In many business applications, the best solution becomes clearer during implementation, and I’m comfortable helping shape that process while keeping the work structured and aligned with the client’s goals. I’m especially interested in .NET applications for internal platforms, admin tools, business automation, and AI-assisted workflow solutions where the technology supports a real business need. I usually prefer fixed-price or milestone-based projects when the scope is clearly defined, because it keeps the process transparent and predictable for both sides. If you need help building, improving, or supporting a .NET desktop application, internal business tool, or custom software solution, I’d be glad to discuss your project.
