Frequently Asked Questions

FAQ

Q.Do I own 100% of the source code and intellectual property?

Yes, absolutely. Upon milestone completion and final handover, all source code, git repositories, and documentation belong completely to you.

Q.How do we track progress during development?

You receive access to a private Git repository, live staging URL updated with every push, and weekly video syncs with clear milestone check-ins.

Q.Can you take over and refactor an existing legacy codebase?

Yes. I frequently conduct code audits, identify performance bottlenecks, modernize legacy Node/Python codebases, and migrate them to scalable stacks.
