I will audit your API security and create a hardening roadmap


About this gig
I will review your REST API or SaaS backend for practical application-security risks and give you a prioritized hardening roadmap.
I focus on:
authentication and authorization flows
tenant and data isolation, including sensitive-data exposure
input validation, error handling, and rate limiting
secrets and configuration boundaries
third-party integrations, logging, auditability, backups, and operational risk
You receive a concise findings report with severity and impact, recommended fixes, assumptions, and a staged remediation plan. If requested, I can implement a bounded set of agreed fixes in a follow-on scope.
This is an architecture and code-review servicenot a penetration test, compliance certification, legal opinion, or guarantee of security. I will not perform intrusive testing without explicit written authorization and a defined scope. Please share your stack, target endpoints, access constraints, and desired outcome before ordering.

FAQ
Will you recommend a rewrite?
Only if evidence supports it. The preferred outcome is usually the smallest credible path that reduces risk and improves delivery, including incremental modernization where appropriate.
Is this a security audit?
No. I can identify visible architecture and engineering risks, but this is not a penetration test, formal security assessment, compliance certification, or legal opinion.
How much of the codebase will you review?
Representative areas agreed during discovery. Exhaustive line-by-line review of every application, service, and repository is excluded unless separately scoped.
Who should join discovery?
Ideally one technical owner and one business stakeholder who can explain priorities, constraints, and past decisions.
