Android App & Infrastructure Audit

My Android app is already live and I hold the source code, admin panel, hosting and domain credentials. What I no longer want is any lingering dependence on the original developer.

I need a seasoned technical partner to walk through the entire stack with me, line-by-line if necessary, and confirm that:
• every repository, key, DNS entry and server instance is in my name
• the code shipped to Google Play matches the code I possess
• there are no hidden back-doors, callbacks or revenue-skimming libraries
• build, release and backup processes can be reproduced without the previous developer

We will begin with a complete audit of the Android codebase, admin panel and server configuration. From there, I’d like recommendations and hands-on help to:
• migrate or harden hosting if required (AWS, GCP, DigitalOcean—open to your advice)
• restructure or initialise a clean Git workflow with proper access control
• set up automated builds, signed releases and off-site backups
• document everything so that any future engineer can step in confidently

Please bring deep experience in Android development, Linux servers, SSL, DNS and source-control best practices. A concise report, remediated code or configs, and a final walkthrough call will mark project completion.

If you have tackled similar “take-over and secure” engagements before, I’d love to hear how you approached them.
