Small Agency Needed to Fix Existing Fintech Platform Bugs

We are looking for an experienced developer or small development agency to help finish and stabilise an existing fintech web platform. The platform is already built and the main user journeys are in place. We have completed extensive testing and documented the current bugs, expected results and test scenarios. This is not a discovery or audit project. We already know the main issues and need someone who can work through them efficiently, fix the root causes and verify the platform against our supplied test cases. Main Scope The work includes a mixture of: - Loan-feed and financial-calculation bugs - Incorrect data appearing under the wrong bank - Incorrect rates, terms and recommendation rankings - Goal-based card and table configuration issues - Frontend field-mapping issues - Authentication and session issues - Document-upload problems - Application-status and email-trigger issues - Responsive frontend bugs - Moving the application hosting to Hostinger Supabase does not need to be rebuilt. It can remain in place for the database and authentication unless a specific bug requires adjustment. Key Issues to Fix Examples of the current issues include: - One bank displaying another bank’s rate, term, payment or interest figures - Incorrect interest rate being selected for one bank - Age-based loan-term limits not being enforced correctly Incorrect recommended terms and ranking order - Loan Amount displaying the wrong value - Zero values displaying as a dash instead of ₱0 - Notable Highlight badges being assigned to the wrong bank - Wrong bank-card metrics displaying under certain user goals - Details tables appearing in the wrong order We will provide: - A documented bug list - Screenshots of the current problems - Expected results - Financial test scenarios - Source-of-truth calculation and content documents - Access to the existing codebase and development environment
