MD Estudio Creativo de Marketing Digital
Stack & technologies

We left WordPress-by-default behind. We build with Astro and Next.js for fast sites, Flutter and Firebase for apps, and AI agents on n8n and WhatsApp Cloud API. Typical result: we lift Core Web Vitals from 30-50 to 75-90+ on mobile, with TTFB under 100 ms.

If your team already works with technologies we don't list here, let's talk. What we don't negotiate: performance, maintainability and code that survives the project.

What we don't install

We say no to what breaks the client's website

We say this because people ask. If what you need lives in one of these stacks, we can talk, but we won't build anything new there. And if your current site runs on WordPress, we migrate it to Astro or Next.js, preserving URLs and SEO, with investment scoped at discovery.

WordPress

25 plugins, chronic vulnerabilities, LCP > 4s, dependency on shared hosting. Core Web Vitals never reaches 75+.

Elementor · Divi · page builders

Bloated CSS and JS injected by default. Editors that break on update. The client stays locked to the builder, not the site.

Wix · Squarespace · Webflow

Good for a quick landing page, not for clients who need real control, serious integrations or portability without rewriting everything.

Typical migration result: Core Web Vitals from 30–50 to 75–90+ on mobile, TTFB from 300–800 ms down to under 100 ms. 100% client ownership from day one: code in Git, domain in your name, zero lock-in.

Frequently asked questions

What we get asked most

  • What tech stack does MD Estudio Creativo use in 2026?

    Frontend: Next.js (apps with heavy admin panels, technical SEO), Astro (high-performance static sites), WordPress (when the client manages content without assistance). Mobile: Flutter with Firebase. AI: Claude API, Gemini Vision, OpenAI API. Messaging: WhatsApp Cloud API, Instagram Graph. Hosting: Vercel and Firebase.

  • Why choose Next.js, Astro and Flutter instead of a single stack?

    We pick the right technology for each problem, not the one we default to. Next.js for apps with complex backends and critical SEO. Astro for fast, bilingual static sites. Flutter for native iOS and Android apps from one codebase. Every decision gets documented during discovery.

  • Do you still use WordPress, or is your stack 100% modern?

    Yes, we use WordPress when the client needs to manage content without recurring technical assistance. It's not legacy, it's the right call for certain cases. For new sites where SEO or performance is critical, we recommend Next.js or Astro.

  • Which AI APIs do you run in production for WhatsApp agents?

    Claude API (Anthropic) for complex reasoning and conversation analysis, Gemini API (Google) for Vision and multimodal, OpenAI API for embeddings and semantic search. We combine them depending on the case. Meta's official WhatsApp Cloud API handles messaging.

  • Do you integrate Colombian payment gateways like Wompi and Bold?

    Yes. Wompi, Bold, Epayco and PayU for Colombia. Stripe for international clients. Integrations run through Firebase Functions or Vercel Functions for webhooks. PCI compliance is delegated to the gateway, we never store card data directly.
