Creating Stripe piece for custom PHP store

I am looking for a freelancer to help me with creating the payment processing functionality of my custom PHP store using the Stripe sandbox and test keys, specifically with Stripe integration. Here are the specific requirements for this project: Functionality to test: - Payment processing Specific requirements and expected outcomes: - Identify any bugs in the payment processing functionality - Improve performance of the payment processing system - Validate the features related to payment processing Ideal skills and experience for the job: - Strong knowledge and experience in PHP and custom store development - Proficiency in Stripe API integration - Familiarity with testing frameworks such as PHPUnit and Behat (although not required) - Attention to detail and ability to identify and resolve issues in a timely manner I've built a simple online store for a friend, and I am not well-versed enough in Stripe or webhooks to set up the payment portion. I have the data for the shopping cart purchase being stored in server PHP sessions, and I need to access those as soon as payment has cleared in order to send out receipt emails and notification emails and then delete them. I will need to collect the customer's information from the Stripe process for this. Just looking for something to use with the stripe test account.
