An AI-assisted product evolution led by me: Codex helped implement the code while I directed the vision, experience, reviews, and bilingual development.

Context & implementation
The accelerated evolution of my 2023 site into a 2026 professional portfolio combined product direction, AI-assisted development, evidence curation, and technical refinement. Codex was used extensively for implementation and incremental changes; I directed expected outcomes, experience decisions, content approvals, and review of revisions. The result uses Next.js, React, and TypeScript, with Portuguese and English content plus documented tests and outstanding checks.

The idea
How could I turn an older portfolio and several training projects into a bilingual, verifiable presentation for international recruiters — using AI to accelerate development without concealing risks?

How it was built
During an intensive iteration cycle, I used Codex as an AI coding agent and other AI tools to support research, organization, and review. The work covered Next.js, React, TypeScript, responsive UX, PT/EN navigation, project case studies, original documents, demo links, and automated tests. Revisions were treated as verifiable code changes, not automatic proof of quality.

My contribution
I led product direction: setting the brief, defining visual and content constraints, comparing alternatives, requesting refinements, reviewing outputs, and prioritizing changes. AI/Codex produced substantial implementation work; my role focused on product direction, evaluating alternatives, and critical review. The effort also covered project presentation, résumé materials, and professional positioning.

What is demonstrated
Commits, source code, and test records document a tangible evolution, including recorded builds and Chromium checks. A later adversarial audit identified real open issues in WebKit, accessibility, demo URLs, and code-to-preview consistency; final validation of these points remains open and documented.
