Work

Selected product engineering case studies

End-to-end work across production platforms, open-source patterns, and complex UX - told as systems, decisions, and outcomes, not a tool list.

Every study names what I owned. The order is depth, not date: what still shapes how I build gets the room, earlier work gets a line.

Featured case studies

  1. Personal · Public · 2026 · Design Engineer & Sole Maintainer

    A production design system, hand-rolled in Next.js and Tailwind v4

    The system that powers this site. Eight foundation layers, twenty-plus components, full voice and accessibility docs, shipped as static pages and read in production.

    Ownership: End-to-end: token architecture, scoped CSS, doc primitives, MDX-free authoring model, build, deploy, observability

    Stack: Next.js 14, React, TypeScript, Tailwind v4, custom CSS variables

    The hard part of a design system is not the tokens, it is the doc primitives. Built the primitives as plain React components so the docs ship the same code that runs in production.

  3. Independent UX Research · 2025 to 2026 · Design Engineer and Platform Owner

    One repo, nine prototype routes, a panel that scores comprehension

    HCI experiment platform with silent variant balancing, prototype versioning (vA1, vA2, vB) from one tree, CDI analytics, and walkthrough mode. Shipped after a pilot that proved the construct but exposed a copy iteration problem.

    Ownership: Full stack: Next.js app, Supabase schema and migrations, balanced assignment API, trilingual i18n, researcher panel, Vercel deploy

    ≈1:38 Pilot CDI ratio (clear vs institutional)

Mobile contract workflows

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

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.
