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

  • Implementing complex validation logic aligned with business and compliance rules
  • Coordinating closely with the client for UAT cycles and production support
  • Ensuring system reliability and supportability in a regulated financial environment

Impact & Outcome

  • Standardized the credit limit increase request process, reducing manual handling
  • Improved request tracking and operational visibility for internal staff
  • Delivered a reliable, audit-friendly system with full SIT/UAT sign-off
