GreenFi

Complex Testing Requirements

GreenFi continues to evolve, with frequent feature updates and UI redesigns. Manual QA no longer meets the team’s speed and quality goals.

Solution

We shifted to a fully automated testing strategy, including unit, screenshot, and end-to-end tests, and made testing an integral part of the development cycle. Our team plans each task with time allocated for writing and updating tests to keep pace with ongoing changes.

‍

Fast Delivery in a Dynamic Workflow

Although the product has been in development for years, the team continues to expand its feature set regularly. This requires fast delivery without sacrificing code quality or long-term maintainability.

Solution

We balanced fast delivery with consistent code quality. Our team improved error tracking, maintained technical debt logs, and built a clear delivery process. This includes automated regression checks, manual testing when needed, and careful planning to avoid shortcuts.

‍

Supporting End-to-End Test Infrastructure

GreenFi is one of the few projects that explicitly requires automated end-to-end tests. Each new feature must support this testing layer, which adds complexity.

Solution

We prepared and maintained the codebase to accommodate e2e testing from day one. Our team ensured proper test coverage and continuously refined the setup to prevent release delays.

Monitoring Stability in Production

In fintech, system stability matters even when no crashes occur, silent errors can cause real damage. It was important to detect issues that standard crash reports might miss and to maintain full visibility into system behavior in production.

Solution

We integrated real-time monitoring with DataDog and built custom logs to detect unusual behavior and anomalies in production. This lets us act fast, even before issues become visible to users.

Securing User Data and Authentication

Handling sensitive user data requires a robust and layered approach to authentication and data protection.

Solution

We implemented multi-factor authentication, biometric login, and strong encryption protocols across the app. These security layers protect both data and access at every step of the user flow.
