React Developer Based in California.
Julio Salvat is a software engineer, UI/UX designer, and character designer specializing in React, full-stack web applications, modern product design, dashboards, branding, 3D characters, and original animated character concepts. A React full stack developer and frontend developer for startups shipping production SPAs and SaaS apps.
React, used the way it's meant to be used.
React rewards developers who understand both how it works and why it works that way. I've been writing React professionally since the class-component era — through the hooks rewrite, the rise of server components, and the Next.js App Router. That history matters because most React performance problems aren't bugs; they're misunderstandings of the render model.
At Skywest, where I'm CTO, I architect React applications that handle real production traffic: data-heavy admin dashboards, multi-role SaaS interfaces, and AI-powered tools with streaming responses. I work in React with TypeScript, Next.js (App Router and Pages), and the surrounding ecosystem — TanStack Query, Zustand, React Hook Form, Radix, Tailwind. I also integrate React frontends with Django, Node.js, and FastAPI backends.
What I bring as a React developer
- Component architecture that scales. Composition over inheritance, sensible boundaries, predictable APIs.
- State management that fits the problem. Local state by default, server state via TanStack Query, global state only when it's actually global.
- Performance you can measure. Profiling with React DevTools, fixing real re-render problems, code-splitting, lazy loading, and avoiding the easy traps.
- Accessibility built in. Semantic HTML, keyboard support, focus management, ARIA only when it's actually needed.
- Forms that don't suck. React Hook Form + Zod, server-side validation, optimistic updates, error UX.
- Type-safe end to end. TypeScript across the boundary — schema, API, client — so refactors are safe.
The kind of React projects I'm strongest at
Data-dense SaaS dashboards, internal tools, B2B admin panels, AI-powered apps with streaming UIs, and Next.js marketing sites that need to be fast and SEO-friendly. If you've got a React app that feels slow, looks dated, or has component spaghetti — that's exactly the kind of work I'm good at fixing.
