FAQ
What do you need from me to get started?
I will need access to your backend source code (usually via a GitHub, GitLab, or Bitbucket repository invite) and any existing API documentation. If we are doing live security testing, I will also need access to a staging or testing environment.
Which frameworks and languages do you specialize in?
I specialize in backend architecture using Elixir (Phoenix framework) and PHP (Laravel). I also have extensive experience working with Node.js and managing databases like PostgreSQL and MySQL for multi-tenant applications.
My application handles sensitive data. Do you sign NDAs?
Absolutely. Working in the FinTech space, I completely understand the critical nature of data privacy and proprietary source code. I am fully willing to sign a Non-Disclosure Agreement (NDA) before we discuss your system architecture.
Are you certified to handle financial or sensitive data?
Yes. I hold certifications as an ISO 27001 Lead Auditor & Implementer and a PCI DSS Practitioner. I apply these strict, enterprise-level compliance standards to every codebase I review and optimize.
Will you actually fix the bugs, or just report them?
The Basic package provides a comprehensive audit and a detailed report of vulnerabilities. If you select the Standard or Premium packages, I will not only report the issues but also actively write the code to patch critical security flaws and optimize performance.
