About this gig

I will review your web app or API for common security problems and fix them.


What I check:

- Login and sessions

- Access control (who can see and change what)

- Input checks and injection problems

- Secrets and API key handling

- Data encryption and key management


What you get:

- A clear written report with the problems, how serious they are and how to fix them

- Fixes in your code (Standard and Premium)

- A retest after the fixes (Premium)


Why me:

- I am a post-quantum security engineer. I build ML-KEM and ML-DSA security into production backends and APIs.

- I built Notabot, a bot-protection startup, and QuanChan, an encrypted platform.


A review lowers risk but does not guarantee that a system is fully safe. Message me before you order.
