About Jc

I design and deploy reliable and scalable automation systems, with a strong specialization around **n8n**: workflow orchestration, webhooks, batch processing, scheduling, error management, alerting, and monitoring. My goal is simple: transform repetitive (or fragile) tasks into fluid, traceable, and maintainable processes by connecting your business tools.

I also develop production-orientedchatbots and conversational assistants**: scenarios, routing, safeguards, logging, and integration with your data. Depending on the need, I leverage **ChatGPT / Claudefor the LLM layer, andElevenLabs(or equivalents) for voice (TTS), to create useful conversational experiences: support, qualification, content generation, action automation, etc. I proceed with a pragmatic approach: tested, versioned, and measured prompts, documented, maintainable, and secure workflows.

On the technical side, I work onexternal API integration(REST, OAuth, signatures),backend development(Node.js, PHP, Python), anddatabases(MySQL). I master industrialization best practices: Git, testing environments, quality assurance, security, and maintenance, containerization (Docker), cloud deployment (DigitalOcean, Google Cloud), and infrastructure as code.

Finally, I have solid experience withJoomla!(architecture, extensions, components/modules/plugins, migrations), as well as ine-commerceandwebmasteringcontexts, where automation provides immediate gains in time and reliability.

If you are looking for a profile capable of framing, building, and running end-to-end **automations and AI assistants**, I can help you.

    Qualification Chatbot
    EDUCATION AND E-LEARNING
    November 2025 - December 2025 (1 month)
    Barcelone, Spain
    For a music school, Cataco designed and deployed aqualification chatbot experienceaimed at automating the first level of contact with families and prospective students. The objective was clear: reduce the administrative load from repetitive requests while improving the quality of interactions with genuinely engaged prospects.

    The chatbot conducts a structured conversation (level, age, instrument, availability, goals, constraints, indicative budget, course preferences, etc.) andanalyzes responses and interactionsto **qualify the request**. After this pre-filtering, it automatically directs each person to the appropriate path:


    • **Qualified Prospects**: Information transmitted to the administration with a clear and actionable summary, enabling quick and relevant follow-up.
    • Non-priority or incomplete requests**: Automatic redirection to the school's **pages, documents, and resources(pricing, schedule, conditions, FAQ, forms), with context-aware responses.

    This approach has allowed the school to **save considerable time**: the administrative team no longer handles all requests indiscriminately but focuses on those identified by the tool as **real prospects**. Result: fewer back-and-forth exchanges, better responsiveness on hot leads, and more serene daily operations, focused on what matters most.

  • Juste une Trace
    Development and maintenance of the label's websites
    CULTURE
    September 2018 - Today (7 years and 9 months)
    Paris, France
    Since 2019, Cataco has been designing, developing, and maintaining the web ecosystem for the Juste-Une-Trace label, based on WordPress and WooCommerce. The goal: to offer a solid showcase for the label and its artists, while ensuring a high-performing online store for selling catalog items (music, merchandising, publications, etc.), with a simple and reliable purchasing process.

    Our work went beyond assembling plugins: we carried out custom developments to meet the label's specific needs. This included creating and adapting templates (themes / child themes), developing dedicated plugins and extensions, and integrating business functionalities (highlighting the catalog, artist pages, editorial content, forms, automations, SEO/performance optimization). We also handle the compatibility of extensions through WordPress/WooCommerce updates, dependency management, and conflict resolution.

    On the operational side, Cataco provides continuous maintenance: secure updates of the core, themes, and plugins, backups, monitoring, bug fixes, performance optimization, security hardening, and improvement of the mobile user experience. We also support the label with e-commerce aspects: payment, tax, and shipping configuration, product catalog management, and checkout process reliability.

    Result: a scalable, maintainable platform designed for longevity, serving the label's image and in-store conversion.

  • Los Amigos Invisibles
    Development and maintenance of the band's website
    CULTURE
    January 2009 - Today (17 years and 5 months)
    Miami, United States
    Cataco handles the design, development, and maintenance of the official website for the band Los Amigos Invisibles using Joomla!, with a focus on performance, security, and scalability. Beyond a showcase site, the platform was conceived as a central hub capable of aggregating content, news, concerts, and sales, while remaining easy to administer.

    A key part of the project involved integrating external APIs to automate content updates and provide a rich experience for fans. We implemented and orchestrated several services: YouTube (videos, playlists, publications), Facebook (feeds and communications), Bandsintown (tour dates, events, and purchase links), Mapbox (mapping and event geolocation), as well as integrating the MissingInk sales system to connect merchandising and the purchasing process. These connections minimize manual tasks, prevent inconsistencies across platforms, and keep the site constantly updated.

    Our work also covers the complete maintenance of the Joomla! ecosystem: core updates, security, performance optimization, compatibility and evolution of extensions (template, plugins, modules, and components), management of testing environments, and deployment procedures. Each evolution is validated with a focus on reliability: regression testing, error handling, and dependency tracking.

    Result: a robust, maintainable website aligned with current standards, capable of centralizing the band's digital presence and effectively connecting content, community, concerts, and sales.
