I provide in-depth manual and automated source code reviews to identify security vulnerabilities, logic errors, and insecure coding practices before attackers exploit them.
Unlike basic linters or scanners, I analyze your code like an attacker and a developer, ensuring both security and maintainability.
What I Review
- Authentication & authorization logic
- Input validation & sanitization
- Insecure cryptography & secrets handling
- Business logic flaws
- OWASP Top 10 issues
- Performance & maintainability risks
Supported Languages

Your code remains fully confidential.
FAQ
Do you use automated tools only?
No. Automated tools assist the process, but the review is primarily manual.
Can you review private repositories?
Yes. Temporary access is sufficient and confidentiality is guaranteed.
Will you fix the code?
I provide secure recommendations. Fixing can be discussed separately.
Do you review embedded / firmware code?
Yes, especially C/C++ and microcontroller-based projects.
