Message

At Berlapak, I led development of a product sourcing and fulfillment platform spanning seller, distributor, and admin apps. By September 2026, it had reached 7,000+ cumulative orders, 80+ transacting sellers, 35+ transacting distributors, and 900+ active products.

I designed the seller inventory and settlement revamp, including FIFO stock consumption and scheduled settlement, and designed real-time seller-distributor chat with Socket.IO. I also led four engineers and worked with product and design to refine requirements before development.

At PT. Clodeo Indonesia Jaya, I built customer service applications in Go and ETL pipelines with Apache Airflow and Prefect. Earlier, I built APIs and web applications for projects including SiCepat, and I now use Claude Code and Codex in the team's shared AI-assisted development workflow.
