Back to original languageAbout Francisco Javier
I am Francisco Carracedo. I develop WooCommerce stores with AI-powered customer experiences for brands in Spain, the UK, and the rest of Europe.
My work is publicly verifiable: I am the author of Trill AI Chat, an AI chatbot plugin published on WordPress.org. I led the commercial launch in April–May 2026 and reconfigured the business model from volume tier to capacity tier based on launch signal, with premium expansion conditioned on quantitative validation criteria.
I build with the pixel-perfect frontend rigor I learned in UK agencies — design fidelity, responsive integrity, cross-browser consistency, Core Web Vitals as a default standard.
Focus Areas:
- WooCommerce Development: custom plugins, checkout optimization, Gutenberg blocks, performance improvements, and Core Web Vitals.
- AI Integration for E-commerce: conversational assistants, product recommendation systems, AEO (Answer Engine Optimisation), content automation — native to WordPress.
- Rescue and modernization of legacy or outdated plugins.
Background: Several years as a WordPress/WooCommerce developer in a UK agency environment (currently at The Fuel Agency, Milton Keynes). Professional English and native Spanish — fluent collaboration with teams in Madrid, Barcelona, Paris, and London.
Projects are invoiced through Greensolutions Pioneers Ltd, a limited company registered in the UK (full invoicing, VAT-ready when required, GDPR-compliant).
Usual arrangements: fixed-price projects (1–4 weeks) or daily rate with defined scope. Availability: 20 hours per week for new projects (equivalent to ~2.5 days/week).
