I’m expanding our software team and need an experienced ASP.NET developer who can focus full-time on building brand-new mobile applications from the ground up. Your work will revolve exclusively around new feature development—no legacy maintenance—so you’ll get to shape architecture decisions, choose modern patterns, and drive best practices. We’re a fully remote company; you’ll collaborate daily with product managers, UX designers, and back-end engineers through Azure DevOps, Git, and Teams. A typical sprint involves designing RESTful APIs in ASP.NET Core, integrating them into a Xamarin or .NET MAUI front end, writing unit tests, and pushing clean, well-documented code through our CI/CD pipeline. To thrive here you should be fluent in C#, comfortable with SOLID principles, and confident optimizing performance for mobile workloads. Experience with cloud services (Azure Functions, App Service, SQL Database) is a strong plus because we rely on them heavily for scalability and monitoring. If building slick, high-performing mobile apps that reach thousands of users excites you, send over your CV (PDF or LinkedIn profile link is fine) along with a brief note highlighting a recent ASP.NET project you’re proud of. I review applications daily and will schedule quick technical calls with shortlisted candidates right away.

ASP.NET Core is my everyday stack - RESTful APIs, .NET MAUI front ends, Azure services, CI/CD pipelines. I have built mobile apps from scratch with exactly this setup so new feature development from the ground up is where I do my best work. I use SOLID principles by default, write proper unit tests, and keep code clean enough that the next developer doesn't curse my name. Azure Functions and App Service are tools I use regularly for scalability. Happy to walk through a recent project on a quick call - just let me know your availability. - Usama
