I've completed 72 jobs on Upwork with a 100% Job Success Score and Top Rated status. I communicate clearly, deliver on time, and write code meant to be maintained, not just shipped. Let's talk about what you're building.

Senior .NET Backend Developer specializing in Enterprise PPM, fintech, payments, and enterprise systems. I build scalable ASP.NET Core and Azure microservices used by 235,000+ users, payment platforms, and enterprise SaaS products where reliability, performance, and maintainability directly impact business outcomes. With 7+ years of experience, I help companies modernize legacy .NET applications, build high-availability backend systems, optimize APIs, and deliver production-ready cloud solutions that continue to scale long after launch.

Need a web application that actually works the way your business needs it to? I build fast, secure, and scalable full stack solutions so you can stop worrying about the tech and focus on running your business. You get one developer who owns the whole product, frontend, backend, and database, instead of a team you have to manage and coordinate. Whether your project is a new idea that needs to go from concept to launch, an existing system that's slow or breaking, or you just need a reliable developer for the long haul, I can take it from planning to production without the back and forth that usually slows things down. What This Means for You ✔️ A modern, responsive Angular application your users actually enjoy using ✔️ A secure, scalable .NET Core API that won't fall over as your traffic grows ✔️ A well designed SQL Server or MySQL database that keeps your data fast and reliable ✔️ Clean Architecture and MediatR so your codebase stays maintainable as your product grows ✔️ A complete solution built end to end, so nothing gets lost between design and delivery ✔️ An existing system that runs faster and causes fewer headaches after I'm done with it ✔️ Third party integrations, authentication, admin panels, and dashboards that just work Where I Can Help Frontend: Angular, React, TypeScript, HTML5, CSS, SCSS, Bootstrap, Reactive Forms Backend: .NET Core, ASP.NET MVC, Web API, REST Architecture, Clean Architecture, MediatR Pattern, FastAPI Database: MySQL, SQL Server, Entity Framework Core, Fluent Migrations, Stored Procedures Also comfortable with: VB.NET, classic ASP.NET Web Forms, Azure (AZ 900 certified), Git, GitHub, Azure DevOps, Stripe integrations, role based systems, multi user apps Why Clients Choose to Work With Me You get clear communication and regular updates, so you always know where your project stands. You get code that's clean and documented, so the next developer (or you) can pick it up easily. You get delivery on time, with quality built in from day one, not rushed at the end. And you get support after launch, because a project isn't finished the moment it ships. Have a project in mind? Send me a message and let's talk about how to build it right.
