Home › Services › Project takeover

Need a developer to take over your project?

Your developer left, the agency stopped replying, or the project is late and unstable. I take over existing .NET and React codebases, find out what is really there, fix what is broken and finish the work.

Questions

Common questions

Short answers before you get in touch.

What do you need to take over a project?

Access to the source code, the hosting or cloud account, and the database. If something is missing, I help you recover it from the previous developer.

How long does a takeover take?

The first review usually takes a few days. After that you get a list of fixes and a timeline for the remaining work.

Will you rewrite everything?

No, not unless it is really needed. I keep what works and replace only what blocks you.

Have a project in mind?

Message me on Upwork, WhatsApp (+92 313 2613274) or LinkedIn with your requirements, and I will reply with a practical plan.
