Things I built, and how they work

Open-source libraries, client builds, and personal experiments. Each entry opens into the full story.

  2. Lyra

    LIVE · Freemium · Pro Rp35rb/bln

    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.
