About this gig

Is a form, component or API request failing in your Angular or ASP.NET Core application?


I am a software engineer with 4+ years of experience building and maintaining financial web applications. I will fix one small, reproducible issue with a clearly agreed scope.


Please message me before ordering with the error, reproduction steps and relevant code so I can confirm that it fits this package.


You receive:

- A focused code change for the agreed bug.

- A short explanation of the cause and fix.

- Verification steps and results.

- One revision for the same issue.


Examples include form validation, a component displaying incorrect data or a small API request/response issue. Delivery is 3 days after receiving the required project information.


New features, migrations, redesigns and production deployment need a separate scope.


I use AI-assisted development tools where appropriate and review and test the code. Please state any restrictions on AI use or code sharing before we agree on the work.
