FAQ
I inherited this app and have no documentation. Can you still work on it?
Yes — that's most of what this gig is. We work from the running application and whatever code you have. No handover notes, no original developer, no problem. The Takeover package includes written documentation of what you actually own.
Do you need remote access to my computer?
No. We work from your repository, or a zip of the code, and can walk through anything on a screen-share. We don't require remote control of your machine.
Can you work on ASP.NET MVC as well as ASP.NET Core?
Yes — classic ASP.NET MVC, .NET Framework, and modern ASP.NET Core. Legacy versions are common in this kind of work.
Do you offer ongoing monthly support?
Yes — a monthly retainer gives you a dedicated .NET developer with priority response for live issues. Most clients who start with a single fix move to this once they see the response time.
How do I know what the fix will cost before I order?
Message me the error, the repo, or a description of what's broken. Most issues can be scoped and quoted within a few minutes.
Can you also deploy it once it's fixed?
Yes — IIS, Windows Server, or Azure. Included in the Takeover package, available as an add-on on the others.
My app has security issues. Can you fix those?
Yes. Security patches and package updates are included in Takeover. For a full penetration test and written report, see our dedicated VAPT gig.
Will you sign an NDA?
Yes, before any code or credentials are shared.
What if the problem turns out to be bigger than expected?
? I'll tell you before starting work, not after. If the scope genuinely exceeds the package, we agree a revised quote up front.

It is rare to find such an experienced and competent developer! This guy is a truly gifted vertically integrated full stack developer who knows the complete DevOps lifecycle. From scratch on paper to containerized deployment and post-deploy / maintenance lifecycle It was a joy to see the magic occur...
