Focus

AI and data-informed workflows

Start with the strongest technical UX case

Data-informed UX

Dashboards, sensors, risk signals, and reporting workflows.

AI product thinking

AI as a trustworthy workflow layer, not a novelty.

Technical fluency

Designing around real inputs, constraints, and implementation trade-offs.

International background

Spain, United States exchange experience, and education in the Netherlands.

Selected work

Case studies built around decisions, constraints, and measurable thinking.

Each project is structured to help hiring teams quickly understand the problem, Alfonso's role, the UX decisions, and what should be measured next.

UX/product case study

Ergonomic Analytics Dashboard

A dashboard UX concept for translating XSens, Delsys, EMG, RULA, %MVC, and JASA data into clear ergonomic risk insight.

Problem: Biomechanical and ergonomic workflows produce dense signals that are difficult for technical users and non-technical stakeholders to interpret consistently.

Why it matters: Risk decisions often depend on confidence, thresholds, and context. A clearer interface can reduce interpretation friction and help teams move from raw signals to responsible action.

Educational UX case study

Design-IT: Gamified Learning Tool

A gamified learning tool for Industrial Design students that turns design briefs, expertise areas, personas, partners, and resources into collaborative decision-making.

Problem: Industrial Design students often need a practical way to connect abstract methods, business framing, and team decisions during early concept development.

Why it matters: Good learning tools make decisions visible. The right game mechanics can help students discuss trade-offs instead of memorizing isolated methods.

AI Portfolio Assistant

A portfolio chatbot designed as an AI/UX product with structured knowledge, internal links, fallback logic, and hallucination guardrails.

Problem: Recruiters have limited time, and portfolios can be hard to navigate when the best evidence is spread across pages.

Why it matters: A helpful assistant can reduce navigation friction, but only if it stays grounded, transparent, and secondary to the normal site structure.

Portfolio assistant

A faster way to find relevant evidence.

The assistant helps recruiters ask targeted questions and jump into the right case study. It is grounded in editable portfolio content and the site still works without it.

This assistant only uses portfolio content and does not store conversations.

Assistant

high confidence

Ask me what to read first, which project shows UX/UI skill, or how Alfonso's technical background connects to product design.

Design principles

Product quality comes from decisions that hold up under real constraints.

The portfolio highlights how Alfonso approaches complex workflows: clarify the goal, expose the right level of evidence, and make the next action obvious.

Start with the decision the user needs to make.

Use progressive disclosure: summary first, depth when needed.

Make confidence, constraints, and uncertainty visible.

Design AI features as accountable workflow support.

Treat accessibility, empty states, and errors as product quality.

Skills and tools

UX/UI craft with enough technical fluency to design responsibly.

A practical mix of research, interface design, prototyping, data visualization, and implementation literacy.
