You will get an ASP.NET Core, Blazor, or React app built, fixed, or improved
Project details
I will build, fix, or improve your ASP.NET Core, Blazor, or React web application.
This project is ideal if you need a new small-to-medium web app, a business tool, an admin panel, API integration, bug fixes, backend logic, authentication, validation, database work, or improvements to an existing project.
I work with both new and existing codebases. If your app is already built, I can review the structure, fix bugs, clean up messy code, and add features without rebuilding everything unless it is truly necessary.
Technologies I work with include ASP.NET Core, Blazor, React, Entity Framework, SQL, REST APIs, JavaScript, TypeScript, Tailwind CSS, Docker, and Git.
My goal is to deliver clean, understandable changes that solve the problem and are easy for you to review.

Fix Bugs in AI/Vibe Website
David did an outstanding job fixing the issues in our React project. He quickly identified bugs, improved the overall code quality, resolved UI and responsiveness problems, and maintained clear communication throughout the entire process.
What stood out most was his attention to detail and transparency. He kept us updated on every fix, improvement, and issue he encountered, which was especially impressive for a project of this size. His progress updates gave us complete confidence that the work was moving in the right direction.
The project was completed much faster than expected, and every requirement was handled professionally and efficiently. We are extremely satisfied with the results and would gladly work with David again on future projects. Highly recommended.

About David
ASP.NET Core & React Developer | Blazor, APIs, Bug Fixes
Tbilisi, Georgia - 7:44 am local time
I can help with:
• ASP.NET Core / Web API bug fixes
• Blazor and React UI fixes
• React components and API integration
• API integration and backend logic
• EF Core and SQL database issues
• Authentication and validation
• Business rules and admin panels
• Docker deployment and production troubleshooting
My experience includes real production work with payments, SSO, Redis caching, AWS S3 storage, logging, automated testing, and CI/CD deployment pipelines.
I’m strongest on the .NET/backend side, including API design, validation, business logic, EF Core, code refactoring, and production bug fixing. I also work with React for UI fixes, component updates, API integration, frontend improvements, and small feature implementation.
If you need someone to understand an existing codebase, find the issue, and make a clean fix without overcomplicating it, I can help.
