I connect LLMs to real business data and workflows, backed by 7 years building production systems at fintech and foodtech companies.

Ranked #1 in Spain for Wordpress Elementor. 90+ Top Rated, working with clients across the US, UK and EU. Most Elementor designers stop at the drag-and-drop layer. I keep going when the design demands custom code. I spent 5 years as a software engineer (Laravel, blockchain infrastructure at Nito-Labs) before design took over, so you get a designer's eye and an engineer's discipline in the same person. When a design hits Elementor's limits, and on real projects it always does, I write the PHP myself instead of telling you the platform can't do it. What I build: - Figma-to-Elementor sites that ship pixel-faithful, no "Elementor doesn't quite do that" caveats - Landing pages tuned for conversion, with 90+ mobile Lighthouse scores as the baseline - WooCommerce stores that feel premium and check out smoothly - Redesigns where the brand evolves and the SEO and speed don't take a hit How I work: - Every build includes a 2-week post-launch fix window at no cost - After launch, most clients stay on a monthly care plan: updates, monitoring, priority fixes and small improvements - Agencies: I also take white-label overflow work under NDA, design or full build Available now. Fluent English, based in Madrid, online well into US East Coast hours. Message me with what you're shipping and you'll have a concrete plan within 24 hours. Stack: Elementor Pro, WordPress, WooCommerce, Figma, PHP, JavaScript, ACF, Stripe, Mailchimp, HubSpot, custom plugin development, landing page optimization, Core Web Vitals, mobile-first design, technical SEO, Figma to WordPress
