CoalTrack
Anti-fraud attendance and automatic payroll for coal-mining crews — server-decided check-ins, an append-only event log, and Indonesian-compliant payslips delivered by email and Telegram.
Vensix
An OpenAI-compatible AI gateway for the Indonesian market — one key for Claude, GPT, Gemini, DeepSeek and Kimi, metered from real upstream cost and paid from a single Rupiah balance topped up by QRIS.
Makmur Motor
An edge-native showroom and inventory CMS for a used-car dealer in Denpasar — Next.js on Cloudflare Workers with D1 and KV, so the owner manages stock, photos and sold units without touching code.
Lavelle
A digital wedding-invitation studio with a staff portal that designs, previews and publishes each invitation to its own subdomain — RSVP and guestbook backed by Supabase with row-level security.

A savings dashboard where every deposit is a real QRIS payment — verified server-side, announced by a Telegram bot, and counted exactly once — running on one Cloudflare Worker with D1.

AR Science Lab
A no-install browser AR teaching suite for primary and middle-school science — 3D magnetic fields over a printed card, animated circuits, six energy-transformation scenes, and an auto-graded quiz with a live teacher dashboard.
Who I am
AI Engineer. Automation Builder. Solutions Architect.
I'm Ksatria — an AI-native engineer from Pontianak, Indonesia who ships production systems end to end. Right now that means an OpenAI-compatible LLM gateway with live cost metering (Vensix), an anti-fraud attendance and payroll platform for mining crews (CoalTrack), and payment-native automation that runs on QRIS webhooks and Telegram bots.
Pontianak · 0° latitudeBefore I built products I broke them — penetration testing for clients on Upwork — and then kept a multi-domain Google Workspace running for a mining company. That habit stuck: I treat every webhook as hostile, every number as something a customer will check, and every deploy as something I will have to support at 3 AM.
I work spec-first, orchestrate AI tools to move fast, and read every line before it ships. If you need someone who can take an idea from a blank repo to a live, paid product — or just want to talk shop about agents and automation — let's talk.
