Top Rated
Project details
Before investing in development, you need to know exactly what you're building, how long it takes, and what it costs. That's where I come in.
I'm a Full Stack Developer and .NET Developer with extensive experience estimating and delivering C#, ASP.NET, and .NET Core projects — from small web apps to complex SaaS platforms. I'll give you a realistic, detailed estimate you can actually build a budget around.
What the estimation includes:
Full breakdown of features and technical scope
Hours and cost estimate per module or milestone
Tech stack recommendation: C# · .NET Core · ASP.NET · React · Angular · SQL Server · MongoDB
Architecture overview and potential technical risks
Timeline with development phases
This is right for you if:
You have a project spec or idea and need a realistic budget
You've received wildly different quotes and want clarity
You're planning a .NET Core or Full Stack web application and need a solid starting point
The deliverable is a structured estimation document with a feature-by-feature breakdown, recommended tech stack, development timeline, and total cost range — clear, honest, and ready to share with your team or board.
Let's get your numbers right.

Full Stack .NET Developer Needed to Help With Payment Integration
Daria did a great job helping us fix our Stripe integration in a .NET app. She quickly found why webhooks weren’t updating the order status and guided us through a clean solution. Clear communication, fast turnaround, and very easy to work with. Would definitely hire again.
