Menezes

Frontend-focused Software Engineer

I build the small pieces that hold big products up. Design systems, platform primitives, and the React and Next.js architecture that lets dozens of teams ship one language.

What I bring to a platform

Six primitives I keep returning to. Each one is the small, invariant piece that lets a big product stay coherent as it grows.

design-systems

Design Systems

Tokens, primitives and governance that keep dozens of teams shipping one language.

platform-primitives

Platform Primitives

Extensible, component-driven portals where new features onboard fast instead of forking.

react-next

React & Next.js

Next.js 15, TypeScript and React Query. Architecture that stays maintainable as it scales.

accessibility

Accessibility

WCAG-aware from the first commit. Keyboard, contrast and semantics are not a later pass.

performance

Performance

Static generation, honest budgets and no scroll-jack. I keep Lighthouse in the green.

product-ux

Product & UX

A product-design background, so I ship interfaces around real user and business outcomes.

build-with-meLet's build the next one

Selected work

Real platforms, not screenshots. Each one is a system that had to hold up for many teams and stay fast for many users.

Thiago Menezes
Louisville, KY

I started in advertising and design, then went deep into engineering. That path is the point. I read a product as a designer and build it as an engineer, so the system I ship is both usable and maintainable.

Today I work as a contract frontend engineer from Louisville, Kentucky, mostly on design systems and platform frontends. I care about accessibility, performance and code that the next person can actually extend.
