◦ Implemented batch payment processing and failed payment retry mechanisms, designed to improve reliability of payment processing ensuring a 100% success rate in payment processing at high scale.

◦ Extensive backend REST API development, with a heavy focus on asynchronous data handling and endpoint security

◦ Created a mock ERP microservice for local development which mimics outstanding, fully or partial paid payments and vendors. Used for reliability testing through generating large amounts of mock data for mass processing.

◦ Developed client-facing features such as payment filtering, resync triggers, and more on both front and back end.

◦ Abstracted system components such as Authentication to improve readability and scalability of implementing new ERPs
