Hello sir,
I understand that you're in need of a cryptocurrency exchange website that integrate PayStack payment, and all of the other features listed.
I am a software developer with over 4 years of experience in web and mobile app development, and I'm quite confident to render my services as the perfect fit for this task.
I'll like to discuss more about the project. Do you have a registered domain, how would you like us to handle hosting. Kindly message me up, and let's bring your website to life.
Best regards
Oluwafemi
