B2B E-Commerce

SIPLah Gramedia & SSIS

National School Procurement & Internal ERP Platforms

Two large-scale B2B systems at Kompas Gramedia: SIPLah (Sistem Informasi Pengadaan di Sekolah) for Indonesia's school procurement market, and SSIS (internal ERP) for omnichannel order processing, real-time inventory, production workflows, and financial modules including partner payables and commission routing.

  • Multi-role order lifecycle: school admin → approval chain → vendor fulfillment → finance reconciliation
  • Complex integrations for payment and logistics gateways
  • Internal ERP modules: omnichannel orders, inventory, production, financial (payables, commissions)
  • Scalable multi-tenant architecture supporting regional procurement offices

Big Horn Guard

Crude Oil Production Monitoring System

An end-to-end IIoT platform for real-time monitoring of crude oil production facilities, developed at PT. AEON Riset & Teknologi. The Node.js server communicates directly with field hardware over the Modbus protocol, ingesting high-frequency sensor telemetry and surfacing it through a live operator dashboard with sub-second response times.

  • Self-contained edge computing application ensuring 24/7 high-availability on industrial PCs
  • Modbus protocol communication with PLCs for pressure, temperature, mass flow, density, and separator readings
  • High-concurrency data streaming via HTTP/WebSocket with sub-second response times
  • Advanced MySQL indexing and data-retention patterns for historical analysis

Enterprise WMS

Warehouse Management System

Multi-Tenant WMS with RBAC & Secure REST API

A multi-tenant Warehouse Management System with a secure REST API built using Golang (Fiber) with JWT authentication. Features a comprehensive administrative web portal with dynamic Role-Based Access Control (RBAC) and customized user permissions for distributed logistics operations.

  • Secure REST API using Golang (Fiber) with JWT authentication
  • Dynamic RBAC with customized user permissions via admin portal
  • Complex relational database schema design for inventory, receiving, putaway, picking, and dispatch
  • Multi-tenant architecture with strict data isolation per organization
