# Mauricio Juba

> Staff Design Engineer — AI-native design systems, enterprise platforms, production code. São Paulo, Brazil (UTC−3). Open to global relocation and remote roles. Ex-Dell, ex-IBM.

Thesis: I build the systems that keep AI-generated software coherent — design systems as LLM context, agents deployed into real operations. Ten years shipping enterprise design at Dell and IBM; today I also ship production software end to end.

## Work (case studies, with measured outcomes)

- [CEMIG](https://mauriciojuba.com/work/cemig): Energy utility, 8M+ customers. Bootstrapped a Carbon-based design system across 5 channels; led a 9-person squad 12+ months. Call-center volume −27%, web/mobile +35%, totem +61%, PIX digital migration 73%. App: 4.7★ / 78K ratings.
- [JET](https://mauriciojuba.com/work/jet): Dell's Salesforce Lightning case-management workflow, 60+ teams. Quantitative before/after usability: task success 58→87% (+29pp), ease-of-use 4.0→6.3/7, ignored fields 40→10%.
- [TOKENS](https://mauriciojuba.com/work/tokens): Dell Design System token architecture — core+semantic, light+dark (4 modes), JSON+CSS pipelines live across dell.com.

## Lab (proof of build)

- OURO_DS: shadcn/ui rebuilt natively in Rust/egui — 60+ components, token-first, governance tests that fail the build on violations. Open source (MIT): https://github.com/Type-zero-labs/ouroboros-ui · docs+live storybook: https://ouroboros-ui.typezerolabs.com
- OUROBOROS: MMO engine + authoring IDE in Rust — 120k LOC, spec-driven development, QUIC + bevy_ecs + wgpu.
- BLIVE PIPELINE: LLM agent pipeline generating commercial travel proposals for a real agency — in production since 2026.
