I architect scalable systems for Enterprise Logistics, Telecommunications, and Fintech sectors.
My focus: Cost Efficiency ($18k/yr savings), High Availability (99.9%), and Clean Architecture.
"Writing code that computers can understand is easy. Writing code that humans can maintain and scale is engineering."
| Industry Sector | The "Big Win" Impact |
|---|---|
| Enterprise Logistics | Legacy Modernization: Migrated a .NET Monolith to Node.js Microservices + Azure Service Bus Integration for a major automotive group. |
| Telecommunications | Infrastructure: Built Custom Bare Metal K8s & IoT System (Modbus/Arduino), saving $18,000/year in vendor costs. |
| Fintech / P2P Lending | Compliance: Engineered OJK-compliant lending engine & stabilized E-Wallet core for a registered financial institution. |
Here is my featured engineering laboratory where I build and test enterprise-grade architectural concepts:
A high-performance digital wallet engine built to handle secure financial transactions with strict data integrity.
- Key Architectural Features:
- Optimistic Concurrency Control (OCC) and Atomic Transactions to absolutely prevent race conditions and double-spending.
- Two-Tier Authentication using short-lived stateless JWTs paired with long-lived Refresh Tokens stored in Redis (Session Kill-Switch mechanism).
- 100% Containerized with multi-stage Docker builds, solving PNPM symlink complexities for zero-downtime deployment.
- Automated Unit Testing with Jest and interactive API documentation via Swagger UI.
