I will build a full stack web app with asp net core and react
Rezaul Karim
About this gig
Are you looking for a reliable full stack developer to build a fast, secure, and scalable web application?
I'm Rezaul, a software engineer with 3+ years of experience building enterprise applications using ASP NET Core, C#, SQL Server, and React js. I've developed ERP, CRM, and accounting systems used in real production environments, along with modern AI powered applications using Semantic Kernel and Ollama.
What I can build for you:
- REST APIs with ASP NET Core (MVC or Controller based)
- React js frontends with clean, responsive UI
- SQL Server database design with Entity Framework Core or Dapper
- User authentication and role based access control
- Background jobs, caching, and rate limiting
- AI powered features using local or cloud LLMs
Why work with me:
- Clean, maintainable, well commented code
- Clear communication throughout the project
- On time delivery with realistic timelines
- Source code included with every order
- Post delivery support for bug fixes
I treat every project like production software, not a quick script. Message me with your requirements before ordering if you're not sure which package fits your project, and I'll help you scope it correctly.

FAQ
Do you provide the source code?
Yes, full source code is included with every package so you have complete ownership of the project.
Can you work with my existing codebase instead of building from scratch?
Yes, I can review, fix, extend, or refactor an existing ASP NET Core or React project. Message me with details first so I can scope it properly.
Do you provide support after delivery?
Yes, I offer a short free support window after delivery to fix any bugs related to the original scope. Ongoing maintenance can be arranged separately.
What do you need from me to get started?
A clear description of your requirements, any design references or wireframes if available, and details about your database or existing system if applicable.
Can you deploy the application for me?
Yes, I can help with deployment to IIS, Docker, or cloud hosting as part of Premium package or as an add on for other packages.
Do you build AI powered features?
Yes, I have hands on experience integrating LLMs (including Ollama and Semantic Kernel) into ASP NET Core applications, including streaming responses and production grade resilience patterns.
