À propos de moi
I build and run production web systems for service businesses: online booking, payment gateway integration, admin dashboards, and automation.
For the past 5+ years I have been the sole developer behind a live booking and payment platform used daily by a multi-branch psychology clinic: Node.js/Express API, MongoDB, six React front-ends, Midtrans payments, WhatsApp and Telegram bots, and Google Ads/Search Console automation. I also built an online assessment platform that ran a 100-participant cohort in one day.
