Hello,
I have read the requirements you need for creating a 2D Payment Gateway. I have been working on PHP, Laravel, Website design, Graphic design, HTML, CSS and other elements which are needed for creating a gateway which will support multicurrency for your NGO. As, I've been doing these for many years which certainly makes me proficient in this field. If you give me the project, I will be able to deliver it within 60 days with precise work. The additional things regarding this project, we can discuss in the chat.
Thanks,
Shahidur
