Frequently asked questions

Questions about website development

What is the difference between the frameworks you use?

We choose the technology based on your project: Astro for ultra-fast websites and static content, Next.js for complex applications with SSR, React for dashboards and SPAs, Vue.js/Nuxt for mid-complexity projects. All with TailwindCSS for consistent design. Rollin Host provides hosting optimized for all of these technologies.

How do you make websites this fast?

We combine multiple strategies: modern frameworks (Astro, Next.js), image optimization (WebP, AVIF), lazy loading, code splitting, a global CDN, smart caching and Rollin Host infrastructure with NVMe SSD and AMD EPYC servers. The result: websites that load in under 1 second.

What does large-scale or multi-level development mean?

These are complex projects such as marketplaces (multiple sellers), SaaS platforms (multiple customers), ERPs, CRMs, franchise systems or any application that needs to support thousands of concurrent users, granular permissions, multi-tenancy and high availability. We use microservices architecture, scalable APIs and elastic infrastructure.

How is AI built into the websites?

We integrate AI in several ways: smart chatbots for 24/7 customer service, personalized product and content recommendations, automatic meta tag generation for SEO, predictive behavior analysis, dynamic interface personalization and process automation with n8n. All in real time, without compromising performance.

Do you build government websites?

Yes. We have experience with government projects and all their requirements: WCAG 2.1 Level AA accessibility, LGPD compliance, hardened security, code audits, hosting within Brazil (Rollin Host Brasil) and complete technical documentation. We serve municipal, state and federal agencies.

How does the members-only/e-learning platform work?

We build complete platforms with user management, access levels, payment gateway integration, a lesson area with videos, PDFs and quizzes, automatic certificates, gamification, student progress tracking and an admin dashboard. A scalable architecture that supports thousands of concurrent students.

Does the e-commerce you build integrate with marketplaces?

Yes. We build online stores that integrate natively with Mercado Livre, Shopee, Amazon, Magazine Luiza and other marketplaces. We also integrate with ERPs (Bling, Tiny, Omie), payment gateways, inventory management, shipping (Correios, Melhor Envio) and marketing tools.

How long does it take to build a website?

It depends on complexity: simple landing pages (5-10 days), corporate websites (15-30 days), full e-commerce (30-60 days), complex platforms and marketplaces (60-120 days), government portals (45-90 days). We deliver incrementally so you can follow the progress.

Do you offer maintenance and support after launch?

Yes. We offer monthly maintenance plans with security updates, bug fixes, content changes, performance optimization, daily backups, 24/7 monitoring, priority technical support and hosting on Rollin Host. There is also an enterprise SLA for mission-critical projects.

How do you keep websites secure?

We implement multiple layers: SSL/TLS, WAF, anti-DDoS protection, input sanitization, JWT/OAuth authentication, rate limiting, automatic backups, vulnerability monitoring, and LGPD and PCI-DSS compliance (for e-commerce). Rollin Host infrastructure adds server-level protection.
