I will do a deep security audit of your web application code


About this gig
Your code is in production. But is it safe?
I will manually audit your codebase and deliver a prioritized report with:
- Every security vulnerability I find (SQL injection, XSS, auth bypass, hardcoded secrets)
- Performance bottlenecks that slow down your users
- Architecture issues that will cost you time as you scale
Each finding includes: severity level (Critical/High/Medium/Low), exact file and line number, a concrete fix with code example.
This is NOT an automated scan. I read your code line by line.
WHAT I NEED FROM YOU:
- Access to your repo (GitHub/GitLab/zip)
- Which part worries you most (security? speed? maintainability?)
LANGUAGES: Python, JavaScript, TypeScript, React, FastAPI, Django, Node.js, Express, Next.js
I respond within 1 hour. Send a message before ordering I'll give you a free quick assessment so you know what to expect.

FAQ
What is your main concern with the codebase?
A: Most clients worry about security before launch, inherited legacy code, or a past incident. Message me with your situation — I'll tell you if an audit is the right move and give you a free quick assessment.
Q: How is this different from automated tools?
A: Automated scanners find pattern-based issues. I find logic-level flaws no tool catches: broken access control, auth bypasses, race conditions. You get a prioritized report you can act on, not 500 warnings.
Q: What do I need to provide
A: Just your code — GitHub/GitLab link or zip file. If you have a specific concern (auth, payments, admin), tell me and I'll focus there first.
Q: What if you don't find any issues?
A: Never happened. Every codebase has issues. But if I find fewer than expected, I expand the audit to cover performance and architecture at no extra cost.
Q: Do you also fix the issues?
A: Basic and Standard include fix suggestions with code examples. Premium: I fix all Critical/High issues and deliver a pull request ready to merge.
What do I need to provide to get started?
Access to your code (GitHub, GitLab, or zip file) and a brief note on your main concerns — security, performance, or maintainability. The more context, the deeper the audit.
What languages and frameworks do you support?
Python, JavaScript/TypeScript, React, FastAPI, Django, Node.js, Express, Next.js, PostgreSQL, Docker. If your stack isn't listed, message me — I likely still can help.
What kind of issues will you find?
Security vulnerabilities (SQL injection, XSS, auth bypass, hardcoded secrets), performance bottlenecks, architecture anti-patterns, and code quality issues. Each finding has severity level and a concrete fix.
Is this an automated scan?
No. I manually review your code line by line, using custom analysis tools to assist — but every finding is verified by hand. This is not a linter report.
What do I get as deliverable?
A prioritized findings report with severity levels (Critical/High/Medium/Low), exact file and line references, and concrete fixes for each issue. Premium includes a 90-day improvement roadmap.
