I will do web app development for scalable dot net saas apps
Shafiur Miju
Level 1
About this gig
Is your next product too big for a template? I do web app development in .NET and C# for scalable SaaS products and business systems. As your software developer, I design the backend, build the interface and deploy it, so your team gets one clean system. I work as your full stack saas developer, from database to screen.
WHAT I DELIVER:
- Web app development on a layered, maintainable .NET and C# architecture
- Backend work: SQL Server, EF Core and secure REST APIs
- Interfaces in React, Blazor or ASP.NET MVC, as your react developer
- Full stack projects that join both ends in one system
- Legacy .NET Framework migration and Azure or AWS deployment
PERFECT FOR: Startups planning a product, businesses replacing a fragile legacy system, and teams that want one hire instead of two.
GOOD TO KNOW: Hosting and cloud costs are billed separately by your provider. Message me your requirements before ordering. Need only an API, or an AI feature? See my other gigs.

I build reliable backend systems for enterprise applications. I develop scalable backend architecture using C# and .NET, high-performance REST APIs with .NET Core, and robust ASP.NET applications. I focus on secure, maintainable systems with clean architecture, authentication, and performance that holds up under real-world load. You get well-structured code, documentation, and clear communication.

FAQ
What does web app development include?
The backend (.NET, C#, SQL Server), the interface (React, Blazor or ASP.NET MVC), user login, and deployment. The package you pick sets the size.
Can you act as my software developer for a SaaS product?
Yes. I handle the backend, the interface and deployment as one project. I cannot promise customers or revenue, but I build for clean code and room to grow.
Do you build the interface too, as a react developer?
Yes. I build the front end in React, Blazor or ASP.NET MVC, whichever fits your project. I recommend one after I read your requirements.
Can you move my old .NET Framework web app to .NET Core?
Yes. I migrate legacy .NET Framework apps to modern .NET. Message me first with a short description of the app and I confirm the scope.
Do you deploy the SaaS app to Azure or AWS?
Yes. I deploy to Azure or AWS and set up the pipeline. The hosting or cloud bill is paid to your provider, not to me.
Will the web app scale as my users grow?
I build a layered architecture, indexed queries and caching so it can grow. I cannot promise a specific traffic number, because it also depends on hosting.
What do you need before you start the web app development?
Your idea in plain words, who will use it, any existing code or designs, and your timeline. A short call or message is enough to begin.
Do you also build custom websites and APIs?
Yes. See my other gig for custom website development and API work. This gig is for web apps and SaaS products.
