Senior Frontend Engineer

Hi, I'm Yunior—a product-minded Senior Frontend Engineer. I turn complex ideas into intuitive, scalable web experiences with React, Next.js, and TypeScript, shipping accessible, high-performance interfaces that are as maintainable as they are polished. I care about creating accessible, maintainable component systems that solve real product problems through thoughtful engineering and user-centered design.

How I build

A practical toolkit for shipping reliable, human-first web products — from architecture and accessibility through performance and delivery.

Frontend Architecture

Scalable React and Next.js apps with component systems, typed contracts, and clean data layers that stay maintainable as they grow.

Accessibility & Standards

WCAG-minded interfaces — semantic HTML, robust focus management, and CSS-first animations that respect reduced-motion preferences.

Performance & Delivery

Core Web Vitals as a first-class concern: lazy loading, code-splitting, and measured Lighthouse budgets shipped through CI.

Quality Tooling

TypeScript strictness, unit + end-to-end coverage with Jest and Playwright, and a CI pipeline that reviews every PR before it lands.
