Description

You have an app that works but you are not sure what is fragile, what is insecure, or what will break when you grow. I will review your codebase, database and deployment, then give you a written priority list: what is actually dangerous, what is merely untidy, and what to fix in what order. What I look at: authentication and access control, database schema and row level security, error handling, deployment configuration, dependency risk, and the places where a user can reach data that is not theirs. I am a backend engineer specializing in multi-tenant SaaS. I have found and reported two real SSRF vulnerabilities in production software, both confirmed fixed. My tenant isolation work is public and runnable on GitHub. You get a written report, not a scanner dump. Every finding includes the specific reason it matters for your app. Send me your stack and I will tell you what I would look at first.
