Indonesia

Message

At FIMOSA, I develop and maintain backend functionality for an ERP system supporting business operations and financial management. I’ve implemented logic for modules including purchases, sales, inventory, and branch management.

I also contribute to financial workflows such as journal entries and transaction management based on Financial Accounting Standards (SAK), along with financial reporting and data processing.

At PT. Geo Santara Indo, I developed fullstack web applications and automated workflows with n8n. I also improved WordPress websites and supported deployment, server configuration, monitoring, and troubleshooting.

Earlier, I developed a secretariat application for archiving and managing documents at RS Harapan Magelang, and built responsive websites at PT Kreasi Orang Muda (Kreasi X). My work has included REST APIs, relational databases, Laravel, and web application development.
