Senior UX Leader · Principal UX Consultant

Curitiba, Brazil — Remote-Ready for Global Opportunities

I help product teams understand what users actually need, and why the current experience falls short of that.

About

Senior UX Leader & Principal Consultant

20+ years of UX practice at the intersection of research, strategy, and design. My work spans qualitative and quantitative research, information architecture, usability evaluation, and product strategy — at principal level, for teams that need more than a report.

I have led engagements for B2B SaaS platforms, legal systems, web hosting products, health tech, and financial services — working embedded with product teams and as an independent consultant for digital agencies. The common thread: making the gap between what users need and what exists impossible to ignore.

I co-founded Faber-Ludens Institute, Brazil's first Interaction Design school, where I directed operations and taught for over a decade. I have trained and mentored hundreds of UX and product professionals — and that perspective on building capability, not just delivering findings, shapes how I work with every team.

AI Practice

AI-native UX practice, built and running in production

I don't use AI tools — I architect AI systems. Over the past year I built a fully operational AI-native UX practice: a governed multi-agent workforce, automated research-to-delivery pipelines, and local ML infrastructure running in daily production. The result is a practice that closes every manual bottleneck in the UX workflow — from research ingestion to client handoff.

Multi-agent orchestration

20+ specialized agents operating as a governed workforce — each with a defined role, formation history, and process assignments. Parallel specialist reviews, cross-agent delegation chains, and equipment checks before new project types. No human mediating technical detail between agents.

Research-to-delivery automation

Full pipeline from raw inputs to shipped deliverables: 131-hour scope estimate generated from a PRD + meeting transcripts + email threads; 44 GitHub Issues created without manual copy-paste; 6 IA deliverables produced with zero human authoring. Multi-locale UX audits across 6 simultaneous locales.

Production ML infrastructure

Local vector search engine (ONNX, Apple MPS) powering dual-corpus knowledge bases — classical library and professional domain KB. Multi-fallback PDF ingestion pipeline. Memory hygiene automation via local LLM at zero API cost. Not a demo — runs in daily production.

Custom MCP server development

Built a purpose-designed RSS MCP server (Python + FastMCP + SQLite) for agent intelligence sweeps. Integrated and configured 12 MCP servers across design, deployment, research, and communication layers.

Spec-to-prototype pipeline

Wireframes generated from IA screen trees via Stitch MCP. HTML/CSS prototypes deployed to Cloudflare Pages in a single command. NotebookLM knowledge bases delivered to clients as self-service Q&A — the AI layer becomes a client deliverable, not just an internal tool.

AI governance design

Token economics as a first-class operational constraint. Modular instruction loading — 75% reduction in always-loaded context. Agent council model for knowledge base curation. Strategic review gates as real approval checkpoints. Organizational design principles applied to AI systems.
