Daniel Quadros

Frontend Engineer with 4+ years of professional experience building scalable, high-performance web applications using React, Next.js, and TypeScript.

I work on production-ready applications for real-world use, collaborating closely with Product, UX/UI, and Backend teams. My day-to-day involves frontend architecture decisions, defining technical standards, improving code quality, and delivering features that balance usability, performance, and maintainability.

My core experience is centered around React and Next.js, with a strong focus on component-driven architecture, state management, API integrations, authentication flows, and performance optimization, always applying solid software engineering practices.

Background

Before focusing exclusively on frontend development, I worked for several years with infrastructure, technical support, and enterprise IT environments. This background contributes to a broader understanding of systems, production stability, operational constraints, and the real-world impact of software decisions.
