Project Summary

Sloboda Studio built a Mock Lender service for a patient financing orchestration platform, delivering a standalone API and a Control Plane UI that let QA simulate lender behavior without relying on external sandboxes. The solution provided deterministic, configurable responses and tooling for manual operations, plus SSO integration and capacity planning for sustained loads. The client reported strong project management and responsiveness.

Key Challenges

Build a configurable, end to end automated testing infrastructure for the patient financing platform
Eliminate fragility in the QA pipeline caused by unstable third party lender sandboxes
Bring deep fintech domain expertise into the design of test coverage

Project Deliverables

Standalone API service (Python/FastAPI) exposing lender integration surface with configurable responses
Control Plane UI (React) for QA to configure behavior rules per scenario
Manual operations tooling for signing transactions, resolving pending applications, and creating external transactions
Auth0 SSO on the Control Plane and Bearer token auth on the API
Design for sustained load of 100 requests per minute with bursts up to 20 requests per second

Project Solution

Sloboda Studio developed a Mock Lender: a standalone API service implemented in Python/FastAPI with MongoDB that mirrors a real lender's integration surface and returns configurable responses. They built a React Control Plane UI for QA to define behavior rules and provided manual operations tooling for production-like actions. The solution includes Auth0 SSO for the Control Plane, Bearer token auth for the API, and was designed to handle sustained and burst loads as specified.

Project Outcome

100% deterministic test behavior removing a major source of flaky tests
Complete test coverage of platform features independent of lender availability
QA team can define new test scenarios through configuration in minutes without engineering work
Project management was solid with deliveries generally on agreed timelines and a responsive PM
