Important

This Offer is for one defined feature added to an existing fintech application.

The application must already have an established codebase/backend or accessible APIs for integration.

Complex financial infrastructure, complete app development, major backend architecture changes, extensive UI redesigns, or multiple new features may require a separate custom offer.

Before starting, I will review your existing application and requirements to confirm that the requested feature can be delivered within the agreed scope and timeframe.
