Full Stack Cybersecurity Upgrade

Our web platform already runs with some basic safeguards, yet the entire stack now needs a thorough security makeover. Both the frontend and backend must be reviewed, reinforced, and documented so that user data stays confidential, common attack vectors are blocked, and every component aligns with relevant compliance requirements (GDPR, PCI-DSS or similar, depending on what you uncover during the audit).

Work begins with a quick assessment of the current codebase and infrastructure to map existing “basic measures.” From there, I expect a clear action plan that covers secure authentication flows, data-at-rest and in-transit encryption, robust input validation, role-based access control, secure session management, logging/alerting, and any hardening steps at the server, API, or deployment pipeline level. Modern, developer-friendly tools are welcome—think OWASP ZAP, Burp Suite, Snyk, ESLint security plugins, Docker Bench, or comparable solutions that fit the stack you discover.

Deliverables
• Detailed security audit report with priority ranking of vulnerabilities
• Implementation of agreed fixes and enhancements across the full stack
• Compliance checklist showing how each requirement is met
• Final penetration test results plus reproducible test scripts
• Hand-off document outlining maintenance steps and rollback instructions

Acceptance criteria
The release passes a repeatable penetration test with no critical or high-severity findings, encryption is enforced end-to-end, and the compliance checklist is signed off without outstanding items.

If this scope fits your skill set, I’m ready to share repo access and move quickly.
