Esteban Fortini

Available for new projects

I build fast, scalable web products, with AI at every stage of the process.

I'm Esteban, a full-stack developer. I work with companies and agencies on websites, applications, automation and CRM integrations. I'm not tied to any one technology: I first understand the project and how it could grow, then choose the stack. I use AI end to end to deliver faster and with better quality. Co-founder of Kūryba Studio. Before code, I spent 7 years coordinating logistics on energy megaprojects.

How I work

Four technical pillars

Every project starts by understanding the business and how it needs to scale. Only then do I choose the technology. These are the areas where I add the most value.

  1. 01

    AI-powered full-stack development

    I use AI across the whole project lifecycle: research, content, development, code review and automation. I build frontends, APIs and lead-tracking backends faster and with higher quality.

    • LLMs & AI Agents
    • Node.js
    • REST APIs
    • SQL / NoSQL
    • TypeScript
  2. 02

    Frontend, UX & performance

    Fast, accessible interfaces with Astro and React: zero JavaScript by default, optimized Core Web Vitals, and designs validated in Figma before writing code.

    • Astro
    • React
    • Next.js
    • Tailwind CSS
    • Figma
  3. 03

    Custom WordPress & Elementor Pro

    Corporate sites clients can manage themselves: dynamic content, custom post types and a clean architecture with no unnecessary plugins.

    • WordPress
    • Elementor Pro
    • ACF / JetEngine
    • WP REST API
  4. 04

    CRM, automation & leads

    I connect forms and sites to CRMs and operational tools: lead capture, AI-assisted qualification and automated follow-up so no inquiry gets lost.

    • HubSpot
    • Make / Webhooks
    • Notion API
    • GA4 / GTM

Experience

From heavy logistics to clean code

7+ years coordinating critical operations shaped the way I work: analytical rigor, on-time delivery and solutions built around the business.
