Indonesia

Message

At PT AGRINDO, I developed ERP and database applications for General Ledger, HR & Payroll, Production & Inventory, Sales & Distribution, and Accounts Receivable/Payable.

As a freelance web developer, I build and deploy web projects using HTML, CSS, JavaScript, React, Node.js, SQLite, and IndexedDB. I also develop responsive interfaces and practice integrating frontend features with APIs and databases.

I created Gunawan Brothers, a responsive business website with a pricing page and WhatsApp order integration. My selected projects also include Modern Portfolio and English Studio, an English-learning website with dictionary and translation features.

I have also managed business operations at MITRA JAYA, CV, a supplier of electrical accessories and home appliances, and managed the Rubber Roll business unit at PT AGRINDO.
