Stuxnet: the worm that crossed from code into physical damage
Most malware steals passwords or encrypts files. Stuxnet broke uranium centrifuges. How a USB-delivered worm crossed the gap between software and the physical world, and what it changed forever.

The first AI-run cyberattack is already here
In 2025 Anthropic reported a state-sponsored group using Claude Code to run most of a hacking campaign on its own. What modern AI hackers actually do, what they still cannot do, and how defenders should respond.

The $1 billion bank heist that a typo stopped
In 2016 hackers used Bangladesh Bank's own SWIFT access to ask the New York Fed for almost a billion dollars. They got $81 million. A misspelled word, a street name and a broken printer saved the rest.

Loupe
A hand-curated gallery of the best design on the web — websites, apps and visuals, each tagged with its fonts, colors and style. Anyone can submit, but everything passes an editorial approval queue first, so the quality bar never drops.
STATSBUZZ
A public, shareable stats & rankings site for tech, AI and startups — every number sourced and dated, wrapped in a bold "bee/hive" brand with dynamic OG share cards. Next.js 16 + Supabase. In active development.
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.
Varo Store
A production PPOB and game top-up store for a village in Riau — an online shop and a tablet point-of-sale running on one Laravel + Vue system, with a 5,900-product catalogue, buyer-pays payment rails, a hash-chained audit trail and automatic supplier failover.
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.
Wedding Saving
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.
Phishing Threat-Intel Case Files
A passive, read-only forensic dissection of a nationwide WhatsApp "free data" scam — a 506-domain network mapped, two hidden origin servers de-cloaked, and a full chain of custody ready for takedown reports.
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.
Cendekia SIAKAD
A full academic information system for a campus — online course registration (KRS), grades and transcripts (KHS), digital advising, and UKT tuition billing — with student, lecturer and admin roles enforced at the database, shipped as an installable PWA on the edge.
Daily Kost
A transit-stay booking platform for Pontianak — rent a room by the 3, 6 or 12 hours or by the day, book with no sign-up, and run the whole operation from a full owner panel.
Who I am
Product Engineer. Mining & Vertical SaaS.
I'm Bintang — an AI-augmented product engineer from Pontianak, Indonesia who ships production systems end to end. Right now that means CoalTrack, an anti-fraud attendance and payroll platform for mining crews; the internal systems of a live internet service provider; Vensix, an OpenAI-compatible LLM gateway; and Luxavero LLC, the US company behind my products.
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.
