Three Disciplines. One Focused Studio.

We don't spread thin across dozens of unrelated offerings. Everything we do lives at the intersection of performance engineering, conversion-focused design, and applied artificial intelligence.

Next.js Application Development

We architect and build ultra-fast web applications using Next.js 14 — React's most production-ready framework. Server-side rendering, static generation, edge caching, and built-in image optimization come standard. The result: pages that score 95+ on Core Web Vitals without compromise.

React · TypeScript · Vercel · Tailwind CSS

Institutional Sites & Landing Pages

A company website should work as hard as your best salesperson. We combine conversion-rate thinking with meticulous responsive design to produce sites that communicate credibility instantly on every screen size — from a 4K monitor to a budget Android device over 4G.

UX Design · SEO-Structured · WCAG Accessible

AI-Powered Process Automation

From intelligent content pipelines and automated customer communication to data extraction workflows and LLM-driven assistants — we integrate artificial intelligence where it creates measurable ROI, using OpenAI, LangChain, and custom models tailored to your operational data.

OpenAI API · LangChain · n8n · Supabase
About Aruana Digital

Built for businesses that refuse to stand still.

Aruana Digital is the operating brand of Gonçalves Web Design Ltda, a São Paulo–based technology studio founded to serve entrepreneurs, growing companies, and established brands that demand precision-engineered digital products — not off-the-shelf templates patched together overnight.

We believe a well-built website or automation is a business asset, not a line-item expense. Every engagement begins with a rigorous discovery process and ends with documented, maintainable code you actually own.

Our Full Story
Principle 01

Ownership First

Every deliverable is yours — source code, hosting credentials, documentation included. No vendor lock-in, ever.

Principle 02

Performance by Default

Lighthouse 90+ and sub-2-second LCP aren't aspirations — they're the baseline every project ships with.

Principle 03

Honest Scope

We quote what we'll build and build what we quote. Transparent timelines, no hidden change-order surprises.

Principle 04

Long-Term Partnership

Our best client relationships span years. We think about your platform's next phase before you've asked.

How We Work

A clear path from brief to launch

No black boxes. Every project follows the same five-phase framework — giving you full visibility at every step and a predictable delivery experience.

  1. Discovery

    We study your business, audience, competitors, and technical environment. No assumptions — only evidence-backed strategy.

  2. Architecture

    Information architecture, wireframes, and tech-stack decisions are finalized and signed off before a single line of production code is written.

  3. Design

    High-fidelity Figma designs — desktop, tablet, and mobile — reviewed together. Brand-consistent, accessible, and conversion-optimized.

  4. Development

    Clean, semantic code in staged sprints. You have a private staging URL from day one and can track progress daily in our shared project board.

  5. Launch & Beyond

    Rigorous QA across browsers and devices, DNS migration support, and a structured handover with training documentation and 30-day post-launch cover.

Our Approach vs. The Usual

Why smart teams choose a dedicated studio

Not every web agency operates the same way. Here's how Aruana Digital compares with the alternatives most businesses consider.

What matters to you Aruana Digital Typical Page-builder / Freelancer
Page load speed Sub-2s LCP on production Server-rendered, CDN-distributed, image-optimized out of the box. Plugin-heavy WordPress sites frequently score <50 on mobile Lighthouse.
Code you actually own Full source transfer at handover Versioned on GitHub, documented, portable to any host. Proprietary builders often lock your content and design to their platform.
SEO foundation Structured data, semantic HTML, Core Web Vitals baked in from the first commit. SEO is usually bolted on via plugins after launch — reactive, not proactive.
AI & automation integration Native first-party integration — no third-party plugin dependency for AI workflows. Rarely available, or offered as expensive upsells through un-maintained plugins.
Post-launch accountability Named point-of-contact, documented SLA and 30-day warranty on all deliverables. Freelancers can become unavailable; agencies rotate account managers.
Scalability Serverless & edge architecture scales to traffic spikes without infrastructure drama. Shared hosting and monolithic CMS setups buckle under unexpected load.
Why Aruana Digital

What makes the difference in practice

These aren't marketing bullet points. They are specific, verifiable standards we've applied across every client engagement since our founding.

Next.js 14 App Router Expertise

We work at the leading edge of the React ecosystem — React Server Components, Streaming SSR, and Partial Prerendering are part of our standard toolkit, not experiments.

Conversion-Oriented Design

Every layout decision is weighed against user psychology and business goals. Beautiful and effective are not trade-offs here — they are prerequisites.

Integrated AI Without the Overhead

We've built AI pipelines that actually run in production — content generation, semantic search, customer-facing chat assistants — connected to your data sources securely.

São Paulo Base, Global Standards

Located in the heart of Avenida Paulista, Brazil's most vibrant tech corridor — with GDPR, LGPD, and international accessibility standards applied as a matter of course.

Supabase & Modern Data Architecture

Row-level security, real-time subscriptions, and edge functions — our database integrations are enterprise-grade from day one, not something you retrofit later.

End-to-End PWA Delivery

Where appropriate, we ship Progressive Web Apps that install on a user's home screen, work offline, and deliver app-grade UX without the friction of an app store.

Selected Projects

Work that speaks for itself

Each project below represents a different facet of what we build — from artisan brand sites that demand emotion and craft, to complex e-commerce infrastructure that must perform flawlessly under real transactional pressure.

Arte do Ferreiro — Brand Website

A bespoke institutional site for an artisan ironwork studio that needed a digital presence as strong as its craft. Built with Next.js and Tailwind CSS, the site delivers fluid navigation, pixel-perfect responsive layouts across every viewport, and Lighthouse scores that place it in the top tier of its category. Static generation keeps it lightning-fast; a custom image pipeline ensures portfolio photography loads beautifully even on slower connections.

  • Sub-1.5s LCP on mobile
  • 100% responsive from 320px to 4K
  • SEO-structured from the ground up
  • Optimized image delivery via Next/Image

Laços da Gigi Pet — Full-Stack E-Commerce

A complete, production-grade e-commerce platform for a São Paulo pet accessories brand. The architecture spans a Next.js storefront, a Supabase backend (row-level security, real-time stock updates, and OAuth authentication), full Melhor Envio shipping integration for dynamic freight calculation, and Asaas for secure, on-page payment processing — eliminating the checkout redirect that kills conversions. Delivered as an installable PWA so customers can add the store to their home screen for repeat purchases with a single tap.

  • Installable PWA with offline cart persistence
  • Supabase RLS database & auth layer
  • Melhor Envio freight API integration
  • Asaas on-page payment — zero redirect
