Hi!
I have read all of your project's requirements for building an online investment system from graphs to payment gateways.
I can do this project with my 5+ years of experience as a full-stack developer, and I will deliver the product with high quality.
I believe I have some queries which need to be clarified. For that, I would request you to start the chat so we could clarify those.
Hope we can discuss more in private chat.
The bid amount and the deadline date can be adjusted after discussing to match your criteria.
Regards.
