About this gig

Your API is your biggest attack surface and the place most testers go shallow. I go deep.


Senior pentester (OSCP, OSWE, CBBH) specialized in REST and GraphQL security. I test the way real attackers and bug bounty hunters do, by hand, chaining small flaws into real impact.


What I test:

- Broken object-level auth (IDOR/BOLA) and broken function-level auth across every endpoint

- Mass assignment, excessive data exposure, and auth/JWT/OAuth flaws

- GraphQL introspection, batching, and rate-limit bypass

- Business logic, injection, and SSRF reachable through the API


What you get:

- A professional report mapping each issue to the OWASP API Top 10, with CVSS severity, raw proof,

  and step-by-step fixes

- An executive summary plus a developer-focused technical section

- One free retest after remediation


Send me your API docs (Swagger/Postman) or base URL and roles, and I will scope it and quote a fixed price before you order.
