Web security Expert needed

I’m preparing to take a public-facing web application live and want an experienced security professional to pressure-test it from every angle. Your mission is to uncover and help remediate vulnerabilities before attackers can find them.

The stack is a typical LAMP back-end with a React front-end; no fancy edge devices yet, just basic hosting, so I’m counting on your expertise with tools such as Burp Suite, OWASP ZAP, Kali Linux, Metasploit, or anything else you rely on for thorough testing. I’m open to the exact blend of vulnerability assessment, penetration testing, and security audit you feel will give us the clearest picture of risk.

Deliverables I need from you:
• A detailed report listing each issue, its severity, reproducible proof-of-concepts, and clear remediation steps.
• A walk-through call (or concise video) so I can fully understand every finding.
• A quick re-test once fixes are deployed to confirm the site is clean.

Success criteria: no critical or high-severity findings left unfixed and a final sign-off report I can share with stakeholders.

Let me know your proposed approach, representative sample reports, and realistic turnaround time so we can lock in the engagement and keep launch on schedule.
