I help companies stabilize, modernize, and extend production .NET applications. I am a senior .NET and C# developer with 13 plus years of experience working on existing enterprise codebases in C#, ASP.NET Core, ASP.NET Web API, SQL Server, Azure, Angular, and React. Most of my work is not greenfield. It is the hard part. Legacy .NET Framework apps, slow APIs, fragile integrations, performance bottlenecks, data issues, and new features that need to ship without breaking what already works. I am comfortable with long running projects, messy code, and complex business logic. If you need someone who can step into an existing system and make safe, useful changes, that is the work I do best. What I can help with ASP.NET Core, C#, and .NET backend development REST API development, third party integrations, authentication, and background jobs Legacy modernization from .NET Framework, ASP.NET MVC, and Web API to modern .NET SQL Server schema design, stored procedures, query tuning, and data fixes Azure deployments, Azure DevOps, CI CD, and production support Angular or React front ends integrated with .NET APIs Bug fixing, refactoring, performance tuning, and scaling existing systems When AI is actually useful, I also build AI workflow automation and RAG systems inside existing .NET applications.

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.
