Mission-critical enterprise procurement automation for the banking sector.
Tech Stack
Key Features
- Regulatory Compliant Workflow Automation
- Core Banking System Integration (IPROC)
- High-Performance SQL Reporting (SSRS)
- Automated Financial Reconciliation
- Enterprise-Grade Security & Audit Logging
The Challenge
Manual, paper-based procurement processes were causing significant delays and compliance risks within the banking infrastructure.
Constraints & Scale
Strict adherence to OJK regulations, seamless integration with legacy Core Banking Systems (IPROC), and deployment within a highly restricted on-premise environment.
System Architecture
Built as a robust ASP.NET Core Monolith to simplify on-premise deployment. Utilized SQL Server with optimized Stored Procedures for complex reporting and Windows Services for background reconciliation.
Key Tradeoffs
Opted for a Monolithic architecture over Microservices to reduce operational complexity in the bank's restricted data center. Used Stored Procedures for critical paths instead of ORM to ensure sub-second performance for heavy financial reports.
Measurable Results
Reduced procurement cycle time by 60%, achieved 100% audit compliance, and successfully managed over $10M in procurement value annually.
Project Details
Engineered a mission-critical Procurement Management System for BTPN (SMBC Group), designed to handle high-volume financial transactions while strictly adhering to banking compliance and OJK regulations. This enterprise-grade solution automates the end-to-end procurement lifecycle, from requisition to payment realization. The system features a complex, dynamic workflow engine capable of handling multi-level approval matrices based on organizational hierarchy and budget limits. I utilized ASP.NET Core and optimized SQL Server stored procedures to ensure sub-second processing times for heavy reporting queries. Key technical achievements include seamless integration with core banking systems (IPROC), automated reconciliation via Windows Services, and a comprehensive audit trail system that tracks every user action for security compliance.
