About this gig
Need a fast, responsive website or web application built with modern tech? I've got you covered.
I'm a senior frontend engineer with 5+ years of experience building websites and web apps for startups, agencies, and small businesses. I've shipped everything from single landing pages to full-stack applications with authentication and databases.
What you get:
- Clean, maintainable code (not a template)
- - Responsive design that works on all devices
- - Fast load times and SEO optimization
- - Deployment to Vercel, Netlify, or your preferred host
- - Figma/design-to-code with pixel-perfect accuracy
Tech I work with: React, Next.js, TypeScript, Tailwind CSS, Node.js, Astro, Prisma, PostgreSQL.
Choose the package that fits your needs:
Starter - one-page site (landing page, portfolio, coming-soon)
Professional - multi-page responsive website
Complete - full web app with backend and database
Not sure which package is right? Send me a message and I'll help you figure it out no commitment needed.

Languages
Portuguese, English
Senior frontend engineer with 5+ years of experience building SaaS products, web apps, and accessible interfaces. I've worked across 8+ client projects in different industries and built the entire frontend of a U.S. startup from scratch — design system, component library, and all.
I specialize in React, TypeScript, and Next.js, and I'm comfortable enough on the backend (Node.js, SQL) to ship full features end-to-end. I also offer accessibility audits using modern contrast standards (APCA or WCAG) to help you build products that work for everyone.

FAQ
Do you work with WordPress/Wix/Squarespace?
No — I build custom-coded websites using React and Next.js. This means better performance, full flexibility, and no platform limitations. If you need a WordPress site, this gig isn't the right fit.
Do you work from a design file or can you design from scratch?
Both! I can implement pixel-perfect layouts from Figma, or work with you to create a clean, modern design if you don't have one yet.
What do I need to provide before you start?
At minimum, I need a clear idea of what you want — reference sites, a brief, or a Figma file all work. For web apps, a short description of the features you need. The more detail, the smoother the process.
Can I see the progress before final delivery?
Absolutely. For Standard and Premium packages I use milestones, so you'll review and approve each phase before I move on. For Basic, I'll share a preview link before marking as complete.
