FAQ
Do I need to message you before ordering?
Yes, please message me first with a short explanation of the issue. This helps me confirm whether it is a small Angular fix, a medium web app issue, or a more complex full-stack debugging task.
What information do you need from me?
Please send anything that helps explain the issue, such as screenshots, browser console errors, API errors, steps to reproduce the bug, source code access, GitHub/Bitbucket link, or a short video showing the problem.
Can you fix Angular and TypeScript bugs?
Yes. I can help with Angular, TypeScript, forms, components, services, routing, API calls, browser console errors, and frontend logic issues.
Can you fix ASP.NET Core API issues too?
Yes. I can help with ASP.NET Core, C#, Web API, backend logic, database connection issues, authentication issues, and API errors.
What counts as a small bug?
A small bug is usually one clear issue, such as a broken button, simple form problem, display issue, TypeScript error, routing problem, or one page not working correctly.
What if the issue is more complex than expected?
If I find that the issue is larger than the package you selected, I will explain what I found before continuing. You can then decide whether to upgrade the order.
Can you work on an existing business application?
Yes. I have experience working on existing business systems, admin dashboards, internal tools, APIs, databases, and web applications.
Can you fix API connection issues between Angular and .NET?
Yes. I can investigate failed API calls, incorrect endpoints, CORS issues, authentication problems, request/response errors, and data not displaying correctly in the frontend.
Do you provide documentation after fixing the issue?
Yes, depending on the package. Standard and Premium packages include a short explanation of what was fixed. More detailed documentation can also be added as an extra.
Can you help if I only have screenshots or an error message?
Yes. You can send what you have first, and I will let you know whether I need code access, logs, or more details to investigate properly.
