What I'm looking for

I'm available for full-time remote work. I take on freelance client engagements through Seakey Studio and the messaging platform as work comes in.

At Sayurmayur, I built and now run the technology behind a grocery retail and delivery business, from its POS and back office to customer and crew apps. The business reached 5,400+ monthly transactions by September 2026, with online orders up 3.3x since launch.

I shipped the four-app platform and its APIs across PHP, Next.js, Flutter, and NestJS, and integrated Midtrans payments. I also built the finance and inventory core, including a stock ledger, SKU-level loss tracing, and campaign margin guards.

I deployed four production LLM agents using Claude Sonnet and OpenClaw to report on sales and stock, suggest restocking, and check promotional margins. Their database tools are read-only and permission-guarded, and every suggestion requires owner approval.

Before Sayurmayur, I developed applications for 700+ KFC Indonesia outlets and worked on web applications and APIs at PT Swirf Labs International and Wahyu Abadi. I now also run Seakey Studio and lead engineering for a confidential end-to-end encrypted messaging platform.
