I have experience in Symfony2 framework.
For now i working on a project, where we have security testing and security perfomance.
So, i can propose to you: i take your project and will doing perfomance and security testing.
This project interesting for me, so - you can chose any freelancer, not only me.
After i finish, i prepare report with suggestions for improvement and send it to you.
And if you like it and agree with it, you pay me.
But there are a few things that you need to know:
1. I have full-time office work, so i can working on this project only on weekends.
2. I can't say now, how long it takes.
3. For work i need to now all about project: source code, environment configuration (server OS, php & db versions, used libraries for images, other external libraries, etc.)
4. I need to now requirements about security, perfomance and project requirements (as one of: which type of images user can upload and how you validate images now).
5. Is project covered by tests?
