With over two decades of fintech expertise, CLPS combines a deep understanding of traditional financial logic with core technical mastery in Mainframe and AS/400 systems. We provide financial institutions with end-to-end consulting and implementation services, spanning technology upgrades, system optimization, digital transformation, and data migration.
Banking System: Consulting & Implementation
Turnkey Digital Transformation
For core system downsizing and migration, we offer lossless strategies and automated validation to ensure a smooth, controllable transition. Additionally, our CoreOptimizer.ai platform leverages AI to analyze COBOL and RPG code, identifying bottlenecks and redundant logic to deliver code-level optimization. This allows our clients to significantly reduce total costs throughout their transformation journey.
System Modernization and Upgrade
Reverse Engineering and Code Refactoring
Logical refactoring of COBOL, RPG, PL/I and other code, transforming procedural code into maintainable and testable modular structures.
Mainframe Feature Simulation and Replacement
Simulating IBM Z and AS400 IO, transaction, encryption, RAS and other features in distributed/cloud-native environments to ensure no performance degradation after transformation.
Technology Upgrade Path
Smooth migration to Linux, Kubernetes, distributed or cloud-native architectures, enhancing transaction processing capabilities and availability.
Code Analysis and System Diagnosis
Code Reverse Analysis
Structured parsing of legacy code such as COBOL/RPG/PL/I, generating call relationship diagrams, data flow diagrams, and business rule tables to solve the no-documentation problem.
Implicit Business Logic Extraction
Restoring decades of accumulated exception branches, boundary conditions, and historical compatibility logic through scenario replay and reverse engineering.
System Health Diagnosis
Locating performance bottlenecks such as excessively long batch processing windows and slow responses, identifying risks such as deep coupling, resource contention, and deadlocks, and outputting quantitative assessment reports.
Full-Path Coverage Modeling
Building business models covering normal, abnormal, and concurrent scenarios to provide a foundation for API-ization and event-driven transformation.
Data Migration and Database Transformation
Lossless Data Migration
Using dual-run and gray-scale validation, CDC/log replication to ensure millisecond-level data consistency, compressing business downtime windows to minute-level.
Automated Migration Validation
Production traffic replay comparison, full-path scenario coverage testing, automatically generating visual difference reports.
Database Transformation
Refactoring COBOL stored procedures into SQL/PL or application-layer code; optimizing performance through indexing, partitioning, and hot/cold tiering.
System Integration and Performance Validation
Legacy System and Microservices Integration
Connecting mainframe core systems to microservices grids and data middle platforms through API gateways and message queues, achieving API-ization and event-driven architecture.
High-Availability Architecture Replacement
Designing multi-active, primary-backup, and self-healing fault solutions in distributed environments, equivalent to or exceeding mainframe RAS features.
Lossless Dual-Run and Gray-Scale Disaster Recovery
Natural disaster recovery capability formed during parallel operation of old and new systems, with second-level rollback to the old system possible if cutover fails.
Real Traffic Replay Testing
Recording long-term real transactions from production environments and replaying them non-intrusively in the new system to validate performance SLAs.
Migration Process Compliance Validation
Generating traceable reports through full-path coverage testing and difference comparison to meet financial industry compliance requirements.
