Credit Limit Increase System
Structured request and processing workflow for a financial services platform
RoleSoftware Engineer / Full-Stack Engineer
Context
A backend system for a financial services platform that allowed customers and internal staff to submit, process, and track credit card limit increase requests through a structured and auditable workflow.
The Problem
The existing process for handling credit limit increase requests was manual and lacked a standardized workflow. This created operational risk, inconsistent handling, and limited auditability — particularly important in a regulated financial services environment.
What I Worked On
- Backend API development for request submission and processing
- Request validation logic and business rule implementation
- Status tracking and lifecycle management for requests
- Enterprise service integration
- Database schema design for audit-friendly data handling
- Production support and SIT/UAT coordination with the client
