Hey!
This is Shivdeep Singh, I'm a full stack web developer and freelance entrepreneur. I just went through the project description that you provided. I know that you are looking for someone from the United States and I can understand why but I'm from Toronto but I think we can work out with that.
According to your description, you are looking someone with LAMP stack experience. Well, I think I the right person for that. I have been creating web apps LAMP stack for years now. I usually work with DigitalOcean, PayPal, SendGrid, MongoDB, Stripe and other APIs. We can have a call conversation for a better understanding of project and requirements.
However, You did not mention anything about the application or software you want me to work on. Please let me know the other details if this hiring is just for the single app or multiple applications.
I'm looking forward to your reply, always here to help you.
Thank you,
Shivdeep Singh
