I will fix, upgrade or finish your asp net core or legacy dotnet web app
Abhinav Grover
About this gig
Your .NET app runs the business, but it is stuck on an old framework, the original developer is gone, or a half-finished feature has been waiting for months.
I fix, upgrade and finish ASP.NET applications. I have worked in .NET for 12+ years, from Web Forms and MVC to .NET Core and Blazor, and one of my integrations processes about 30,000 orders a month.
What I take on:
- Bugs, crashes and slow pages traced to the root cause
- Upgrades from .NET Framework or MVC to ASP.NET Core
- Unfinished features and APIs completed and tested
- Entity Framework, SQL Server and PostgreSQL fixes
- Login, JWT, role-based access and Active Directory SSO
You get full source code, Git history and setup notes. Every job starts with reading your code and a fixed price.
Not included: mobile apps or full rewrites (ask for a custom offer).
Message me before ordering with your .NET version and what is wrong.

I fix and finish web apps that stalled: apps built with Lovable, Bolt, Base44, Replit or Cursor that work in a demo but break with real users, and projects a previous developer left half-done.
I have 12+ years of experience and lead a small in-house team of developers, QA and DevOps engineers. I review every delivery myself. Stack: Laravel, ASP.NET Core, React, Next.js, Node.js, Python, AWS.
Every job starts with reading your code and a fixed price. If it is a two-hour fix, I will say so.

FAQ
Which .NET versions do you work with?
.NET Framework 4.x, Web Forms, MVC, .NET Core and current .NET versions, plus Blazor. WinForms and WPF desktop apps on request.
Will you sign an NDA?
Yes. Share your NDA before the order starts and I will sign it. Your code and data stay private and are not reused.
What access do you need to start?
Access to the code repository and a staging server or database copy. I work on a separate branch and you approve before anything goes live. No passwords in chat.
Can you upgrade my app from .NET Framework to ASP.NET Core?
Yes. I start with an audit, then a step by step plan so the app keeps running while it is upgraded. You get a fixed price for each stage before any work starts.
