01

Identity

Rafael's identity should read like his work: specific, technically grounded, and open to scrutiny.

Technical

Use exact language and concrete fields of work.

Direct

Lead with the point; remove ornamental phrasing.

Credible

Support statements with affiliations, work, or links.

Understated

Let evidence carry authority; avoid self-promotion.

02

Color

Reuse the current palette. Blue is reserved for links, active states, and useful emphasis.

03

Typography

Security, privacy, distributed systems, interoperability.

Use one neutral sans-serif family. Weight, size, and spacing establish hierarchy without changing the site's voice.

04

Layout

A narrow navigation bar frames a centered reading surface. Content uses one main column, with two-column splits only for portraits, affiliations, or short reference material.

  • Width: readable, centered, consistent.
  • Rhythm: generous section gaps, compact paragraphs.
  • Mobile: stack content; keep order and hierarchy.

Interface

Links and actions

Read academic work Contact Rafael

Prefer text links. Use a bordered action only when a clear next step needs emphasis.

Interaction

  • Active navigation is blue or underlined, never boxed.
  • Keyboard focus uses a visible blue outline.
  • Motion is limited to short color and underline transitions.
  • Borders are thin, square, and functional.

06

Voice

Write in the first person. State the role, the work, and its context. Link evidence at the point where it matters.

Biography pattern

I am a research engineer working on security and privacy, distributed systems, blockchain interoperability, and interoperability for AI agents.

Consulting call to action

For research, technical review, or implementation support, get in touch.

Examples demonstrate structure and tone. Final wording should always be checked against Rafael's current biography and CV.
