Hi,
As I'm a professional hybrid Mobile app developer who has over 5 years, I'm interested in payment integration.
I have deep knowledge in java, kotlin, API integration, and payment platforms.
Please share in detail requirements.
If you don't mind, I can complete your project according to your requirements.
I think this is the right opportunity for you to work with the right person.
I'm looking forward to meeting with you, and learning more about this opportunity!
Best regards
