Overview
Go is a fintech platform that provides digital wallet services, gift cards, cashback rewards, and merchant payments through a unified ecosystem. The platform enables users to manage financial transactions securely while offering businesses integrated payment and loyalty solutions.
Problem & Solution
The Challenge
As the platform evolved, business requirements changed frequently, introducing new payment flows, KYC rules, order states, cashback policies, and merchant-specific behaviors. The challenge was to accommodate these changes without creating tightly coupled code or breaking existing functionality.
The Engineering Solution
I continuously refactored the application toward a modular architecture by isolating business rules into dedicated services, reusable actions, and domain-specific classes. This reduced coupling, improved testability, and allowed new requirements to be implemented with minimal impact on existing workflows.
Engineering Deep Dive
