Every action returns to the record. One exploratory mobile product told through authored design decisions here and working behavior on the engineering portfolio.

Platform trilogy · 2025–2026

Rádio Alvorada TV

One gospel media brand, three independent deploys — public website, 24/7 audio tooling, and custom live video — each designed to collapse complexity for audiences and operators.

  1. Part 1 of 4

    Where every surface starts: tokens, components, and patterns

    The foundational design system behind the platform: semantic tokens, component variant rules, accessibility foundations, and 24 documented sections that ground the website, audio tooling, and live TV.

    Define the palette, type, spacing, and components once, then every surface inherits the same warm, reverent identity without drift.

  2. Part 3 of 4

    Broadcast from the browser, not a desktop encoder

    Self-hosted Icecast on Oracle Always Free with a WebSocket bridge — operators go live from the browser, listeners tune in via MP3.

    Remove BUTT/OBS from the operator path by accepting a small bridge on the server — complexity moves where volunteers never see it.

  1. The upload failed. The fix is 2 KB.

    A zero-dependency in-browser image engine: compress, resize, and convert with HEIC input, AVIF output, and a never-bigger-output guarantee. Shipped as an npm library and a free PWA tool.

    Size limits break uploads in the exact services people cannot abandon. Move the fix into the browser, keep the core tiny, and never return a bigger file.

  2. Users finish the task, and still cannot explain what happened

    International HCI experiment that isolates interface language as the only variable across banking, healthcare, and government flows. Empirically validating cognitive distance as a measurable construct distinct from cognitive load.

    Build the instrument that makes 'success without comprehension' visible. Then ship it as a live, international study.
