Cloud Deployment & Backdoor Audit

I have a complete code-base that now needs to live on a cloud server. The immediate goal is twofold:
1) install and configure the application so it runs reliably in the cloud environment I provide, and
2) comb through every file, dependency, and configuration to confirm there are no hidden backdoors, malicious packages, or insecure default settings left behind after development.

I’m deploying to a cloud server (provider is flexible, so please be comfortable with AWS, Azure, or GCP). You’ll set up the runtime stack, handle environment variables, connect the database, and push the first production build. While doing so, perform a thorough security audit: manual inspection, automated scanners, and any static-code-analysis tools you trust. If something suspicious appears, document the finding, patch or remove it, and explain the fix.

Deliverables
• Application running on my cloud instance with zero critical errors
• Security report summarising tests performed and confirmed clean results (or the remediation steps taken)
• Deployment notes or script so I can reproduce the setup in the future

I’ll be available for quick access credentials and clarifications, and I expect clear, concise progress updates throughout.
