At PT Catur Sukses Internasional, I own 15+ production applications across logistics, sales, finance, and internal workflows. I built MIDCSI System Hub, an ERP integration platform serving 16 internal apps and external vendors, with a live Microsoft Dynamics NAV sync layer.
I also built a custom AI agent layer without a framework, using a tool-calling loop across ERP tools, embedding retrieval, and prompt-injection guardrails. My work includes multi-tenant systems, Redis distributed locking, and PostgreSQL query optimization.
Outside that work, I’ve developed products including a warehouse queue management system, a mobile POS, and an approval workflow engine. I’ve also worked on AI projects for automated content production and WhatsApp customer service.
