Throughout my career, I've worked on complex software projects where reliability, performance, maintainability, and clean architecture are critical. I specialize in designing robust backend systems with C# and .NET, while also working across frontend, databases, cloud infrastructure, and DevOps when the project requires full-stack ownership. What I deliver: - Build scalable REST APIs using C#, ASP.NET Core, and .NET 6/7/8 - Design enterprise applications using Clean Architecture, SOLID, CQRS, MediatR, and Repository patterns - Develop microservices and distributed backend systems - Build modern web applications using React.js, Angular, Blazor, TypeScript, and JavaScript - Design and optimize PostgreSQL, SQL Server, and Oracle databases - Improve application performance through query optimization, Redis caching, asynchronous processing, and efficient API design - Build background services, scheduled jobs, and workflow automation - Integrate third-party APIs, enterprise systems, payment platforms, and SaaS services - Containerize applications with Docker and support cloud deployments - Build CI/CD pipelines using GitHub Actions and modern DevOps practices - Write reliable automated tests using xUnit, NUnit, Moq, and integration testing frameworks - Debug production issues, perform root-cause analysis, and improve system stability Core technologies: C#, .NET, ASP.NET Core, Web API, Entity Framework Core, LINQ, SQL Server, PostgreSQL, Oracle, Redis, Docker, Azure, AWS, Microservices, REST APIs, CQRS, MediatR, Clean Architecture, React.js, Angular, Blazor, TypeScript, JavaScript, GitHub Actions, CI/CD, xUnit, NUnit, Playwright My approach is simple: understand the business problem first, design the right technical solution, and deliver clean, maintainable software that can continue to evolve as the business grows. What I Can Help You With ------------------------------- ✔ Legacy ASP.NET / .NET Framework → .NET 8 Migration ✔ Full Stack SaaS Development (.NET + Angular / React) ✔ Angular & React Front-End Development ✔ Enterprise SaaS Development ✔ Enterprise Web Applications ✔ ASP.NET Core Web Applications ✔ ASP.NET Core APIs ✔ REST API Development & Integration ✔ Blazor Applications (Blazor Server & Blazor WebAssembly) ✔ Angular Migration & Upgrades ✔ React Application Development ✔ Azure Cloud Solutions ✔ Database Design & SQL Server Optimization ✔ SQL Server Performance Optimization ✔ Application Modernization ✔ Technical Architecture & Code Reviews ✔ Team Leadership & Mentoring ✔ Rescue & Completion of Existing Projects ✔ Performance Optimization MY EXPERTISE -------------------- ✔Backend • C# • .NET Framework • ASP.NET MVC • ASP.NET Core • Web API • Minimal APIs • Entity Framework • Dapper • SQL Server • MySQL ✔ Frontend • Angular (AngularJS through Angular 20+) • React • Next.js • Blazor Server • Blazor WebAssembly • JavaScript • TypeScript • HTML5 • CSS3 • Bootstrap • jQuery ✔ Cloud & DevOps • Microsoft Azure • Azure Functions • Azure App Services • Azure Storage • Azure DevOps • Docker • Kubernetes • CI/CD • Jenkins ✔ AI Expertise I help businesses integrate AI into existing applications and develop new AI-powered products.
