IBK Electronic Document & Court Integration System

Financial legal document automation with court system integration

Project Overview

Financial legal workflow automation platform through IBK (Industrial Bank of Korea) electronic approval system and court system integration. Implemented comprehensive digital transformation of the entire process including Java legacy modernization (6→8), Spring Batch-based large-scale document migration, automatic interest calculation, HWP document generation, and court document delivery automation.

Challenge

Needed to digitize complex financial legal processes, modernize legacy Java systems, handle large-scale electronic document migration, implement secure court system integration, and ensure compliance with financial regulations and data security while maintaining business continuity.

Solution

Legacy System Modernization

Upgraded 10+ year old Java 6-based system to Java 8 and transitioned to modern architecture.

Java 6 → Java 8 migration: Performance improvement and security enhancement

Legacy code refactoring: Improved maintainability and extensibility

Database optimization: Query performance and indexing improvements

System stability enhancement: Error handling and monitoring improvements

Spring Batch-based Document Migration

Built batch processing system for safe and efficient migration of large-scale electronic documents.

Large-scale document batch processing: Spring Batch-based stable migration

Data integrity assurance: Checksum and validation logic implementation

Error recovery mechanism: Automatic retry and recovery for failed jobs

Progress monitoring: Real-time migration status tracking
