Commerce platform for Indonesian small businesses: a shareable storefront, QR ordering at the table, and cashier and kitchen queues that update live, with nothing to install. I build the product and own the money side of it, from the 2.5% per-sale model through to merchant reporting.

Plagiarism and AI-detection service that gives Indonesian students an affordable alternative to Turnitin, with paraphrasing and document repair alongside it. I build the app and run the cluster underneath it, where queued workers return a checked document in minutes, around the clock.

Creator gifting platform for Indonesian streamers, where a viewer's paid gift becomes a live alert on stream seconds later. I work across the API and the web app on a team that has taken it past 10,000 users and 2,500 creators.
