I'm Bintang. I build the systems everything else runs on.

Front-End and AI-Native Engineer, four years deep in the React ecosystem. I've shipped a cross-platform design token system, an O(1) CSS runtime, a build-time compiler, and a WSA-winning waste-management ERP. Front-end first, but I follow the work down the stack: Go and .NET services (Framework and Core), deployed to the edge on Cloudflare Workers and Hono, with AWS EC2 when the job calls for it.

  1. Lyra

    Lyra

    A form builder for Indonesia with payments built in. Create a form, collect answers, and accept money on the same screen — Virtual Account, QRIS, and e-wallets render inline, settle to a creator wallet, and pay out to any bank. Built solo, end to end.

  2. Aurora PDF

    Aurora PDF

    A serverless document utility tool using WebAssembly to execute PDF conversions, compressions, and local OCR parsing entirely within the user's browser runtime — eliminating external server overhead and ensuring complete privacy.

  3. Quasar

    Quasar

    An all-in-one, privacy-first developer tools suite with 120+ data and code utilities that run entirely client-side. Built on a registry-driven architecture where a single source of truth powers routing, navigation, fuzzy search, and SEO — adding a tool is one entry plus a pure, fully tested engine function.

  4. Stareezy UI

    Stareezy UI

    A fully typed, object-based design token system and cross-platform component library for React Native and web. Authored custom Babel and Vite compiler extensions to extract tokens at build-time into atomic CSS variables, delivering flat O(1) runtime evaluation metrics.
