I will do secure code review and find security vulnerabilities


About this gig
Your code works but is it safe? I'll manually review your source code and find the security bugs that scanners and normal code reviews miss.
I'm an offensive security researcher with a bug-bounty track record across HackerOne, Bugcrowd, Intigriti and YesWeHack I find real, exploitable flaws for a living, and I've done source-level security audits of production cryptographic and backend libraries.
I review for: injection, broken access control (IDOR/BOLA), authentication & session flaws, SSRF, insecure crypto usage, secrets in code, unsafe deserialization, and logic bugs mapped to OWASP.
⭐ Specialty: review of cryptographic implementations and security-sensitive backend logic.
Languages I cover: JavaScript/TypeScript (Node.js), Python, PHP, Java, Go plus C/C++ and Rust for systems & cryptographic code (my specialty).
You get a clear report each issue with severity, the exact file/line, why it's exploitable, and how to fix it. Free follow-up questions after delivery. Send me your repo or files for a custom quote.

FAQ
Do you just run a scanner?
No, the review is manual. Scanners miss access-control and logic bugs, which are usually the ones that actually hurt.
What do you need from me?
A link or zip of the code, what it does, and any areas you're worried about.
Can you review AI-generated / "vibe-coded" apps?
Yes, send the repo and I'll flag the security risks.
