Project details
You will get a production ready SaaS MVP built with .NET and Azure designed for fast launch, clean architecture, and future scalability. I develop SaaS backend systems with secure authentication, business logic, database design, API integration, and cloud ready deployment using modern .NET technologies and Azure services.
This service is ideal for startups, founders, and businesses that need a strong MVP foundation without overbuilding early stage products.
My focus is on building maintainable SaaS architecture, secure user flows, scalable APIs, and Azure ready deployment so your MVP is ready for real users and future feature growth.

Visual Studio C# .NET SQL Issue Resolution
Ajith was great to work with and incredibly knowledgeable. I’d highly recommend him if you run into any roadblocks like we did.
He helped us get a new ASP.NET C# project running in Visual Studio 2026 after moving from our older 2012 setup. We ran into several version‑related issues—scope errors, SQL connectivity, a small code bug, IE configuration, and publishing—but he walked us through all of it.
We wouldn’t have met our deadline without his expertise.
