I will migrate legacy asp net framework to asp net core and fix vue bugs
Le Vy
About this gig
Your ASP.NET Core, C# or Vue.js app is throwing errors, crashing, or behaving in a way nobody can explain? I find the real cause and fix it properly.
WHAT I FIX
- Backend: C#, ASP.NET Core, Web API, EF Core, Dapper, async issues
- Frontend: Vue 2 and Vue 3, TypeScript, JavaScript, state and rendering bugs
- Authentication and JWT problems, broken or slow REST endpoints
- Database: bad queries, missing indexes, timeouts, failed migrations
- Deployment on IIS, Docker, Nginx or Linux
HOW I WORK
Step one: you send the error message, a screen recording, or repo access.
Step two: I reproduce it and find the actual root cause.
Step three: I fix it, test it, and explain in plain language what was wrong.
WHY ME
3+ years building production systems used by tens of thousands of people, including exam and survey platforms serving 20,000+ candidates and 50,000+ teachers. I have debugged the kind of failures that only show up under real load.
Not sure if your bug fits? Message me the error first and I will tell you honestly whether I can fix it and which package you need.

FAQ
Do you need access to my code?
Yes. GitHub, GitLab, Bitbucket or a zip file all work. For small issues, a screen recording plus the error log is often enough to start.
What if the bug is bigger than the package I bought?
I tell you before I start. You only upgrade if you agree with the new scope, and I never begin extra work without your approval.
Which technologies do you actually work with?
C#, ASP.NET Core, Vue 2 and 3, TypeScript, Go, SQL Server, MySQL, PostgreSQL, MongoDB, Redis and Docker. If your stack is outside this, I will say so instead of wasting your money.
