Hello sir/mam,
I recently made a CRUD app for my own application and its built with OOP and Mysqli and I did all the possible security in it like csrf, xss, and sql injection attack I will also provide free security update in future.
I believe for this project our CRUD app is perfect and easy to maintain
I like to be a long term team player with you.
If you have any questions, feel free to ask me and if you like to start work together on this project contact me.
