Backend Developer for Payment Gateway Integration
Skills Required
Description
Integrating multiple payment gateways into a platform requires precision, security, and efficiency. This role focuses on building backend systems that make payments seamless for users.
Python will serve as the foundation, with frameworks and libraries tailored for API handling and transaction workflows.
Databases like MySQL and MongoDB will be used to store transaction records, customer details, and logs. The developer should know when to use relational vs. non-relational storage.
Docker will help standardize the development environment. Containerization ensures that services behave consistently during testing and deployment.
Some frontend collaboration may be required. Skills in JavaScript, TypeScript, and React.js will be useful for coordinating with UI developers to ensure payment flows look and function correctly.
GraphQL could be introduced for flexible querying between services. This helps improve efficiency when handling complex payment data.
Core responsibilities for this project include:
Implementing payment gateway APIs (e.g., Stripe, PayPal, local providers)
Securing all transactions with encryption and tokenization
Setting up error handling and retries for failed payments
Scalability must be a consideration. The system should handle spikes in payment volume without delays or downtime.
Testing is critical. The developer must write automated tests to validate workflows...
