Your users trust you with their data. I make sure that trust is never broken — implementing battle-tested security at every layer.
Military-grade AES-256-GCM encryption for files and sensitive data — unbreakable without the key.
PBKDF2 / bcrypt password hashing so stored passwords are never readable, even if the database is breached.
Stateless, secure token-based login systems — users authenticated safely without exposing session data.
SSL certificate configuration and HTTPS enforcement so all data in transit is encrypted end-to-end.
Input validation, output encoding, and parameterized queries to block XSS attacks and SQL injection.
Review your existing code and app for vulnerabilities — with a detailed report and fixes applied.
Identify what data needs protection, what attack surfaces exist, and what security standards apply.
Define encryption schemes, authentication flows, and input validation rules for your specific app.
Apply encryption, hashing, JWT auth, HTTPS, and validation layers throughout the codebase.
Attempt common attacks on your own app to verify protections work before real attackers can find them.
Full security report detailing what was done, why, and what to keep in mind going forward.
