About Me
I’m Bintang (Ksatria Bintang Samudra) — an AI-native product engineer from Pontianak, the Indonesian city that sits right on the equator. I build software for mining and telecom operators: CoalTrack, an anti-fraud attendance and payroll platform for coal mining, and the internal systems of a live internet service provider, where I work as Systems Developer. My products — and my client work — run under Luxavero LLC, my company registered in Wyoming, USA.
My path is a little unusual. I started analysing social-media data for clients on Upwork, moved into penetration testing, then spent a year and a half administering Google Workspace for a mining company. Each stop left a habit I still use: respect data, assume nothing is safe by default, and automate whatever doesn’t need a human.
Today I work spec-first and AI-orchestrated — Claude Code and Cursor do a lot of the typing, and I own every decision. Alongside the engineering I’m finishing a management degree at STIE Anindya Guna (expected 2027). If you need something real shipped quickly, without cutting corners on security or data integrity, let’s talk.
Quick Facts
Expertise
What I’ve shipped
Concrete things I built end-to-end, with the scope that matters. Every link is live.
- CoalTrack — anti-fraud workforce & payroll for mining2026
Founder and sole developer. Flutter + Laravel 12 + PostgreSQL 16, 236 commits, 400+ automated tests. Tamper-resistant attendance (server time, device binding, mock-GPS rejection) feeding Indonesian statutory payroll, bank files and payslips in 7 languages. In TestFlight and Google Play closed testing.
- Rimba Raya — operations systems for a live ISP2026
Five internal systems I built and operate: an operations portal (Vue 3 + Supabase, row-level security, 46 production migrations), barcode inventory with 2FA, payslips and employee intake — wired to RADIUS/MikroTik provisioning, QRIS billing and WhatsApp notifications.
- Vensix — OpenAI-compatible AI gateway2026
One key, one Rupiah balance: routes to Claude, GPT, Gemini, DeepSeek and Kimi with live cost-based metering, QRIS top-ups and automated hosting provisioning.
- Makmur Motor — edge-native showroom & CMS2026
Next.js on Cloudflare Workers with D1 and KV; a dealership runs its own inventory, photos and SEO from an admin panel.
- Lavelle — digital wedding-invitation studio (Luxavero LLC)2026
Staff portal with live preview, Supabase row-level security and one-click publishing of each invitation to its own subdomain.
- Phishing threat-intel case files2026
Passive OSINT dissection of a WhatsApp phishing / CPA-fraud campaign: 500+ related domains mapped, chain-of-custody manifests, abuse reports.
How I work
The rules behind everything on this site — and everything I ship for clients.
- Spec first
- Every build starts with scope, constraints, contracts and acceptance criteria. The AI inherits the spec — never the guesswork.
- AI-orchestrated
- Claude Code, Cursor and custom prompt chains do the typing. The right tool for each layer, not one hammer for every nail.
- Human-verified
- I read what the tools produce, test it, and own every architectural decision, security boundary and trade-off.
- Security by default
- Pentesting taught me to assume nothing is safe: server-side verification, least privilege, idempotent payments, no secrets in the client.
