Fullstack AI Engineer · Malang, Indonesia
I build production systems for events and small businesses in Malang: registration and payment sites, admin dashboards, accounting software, WhatsApp and Telegram bots, and AI features that run on top of them. I usually own a project from the database schema to the deployment, and I keep the servers they run on healthy.
Since August 2026 I work as Fullstack AI Engineer & Technical Lead at D'Production, an event organizer in Malang. I am also an Information Systems student at Universitas Ma Chung.

- WhatsApp bots that confirm payments, answer FAQs, and send reminders. Messages go through an outbox with rate limits and office hours.
- Telegram bots that turn a chat message into a finished invoice or receipt PDF, and that read receipts with OCR.
- A Discord operations bot for server status, logs, deploy windows, and approval buttons.
- LLM features: a course tutor, customer service replies in the company's writing style, and AI agents that help run the servers.
Across my repositories the code is mostly TypeScript, then JavaScript, Python, HTML and CSS, SQL (PL/pgSQL), Shell, and a little PHP, Java, and C. Most of my web work uses React through Next.js.
