About me
I'm a full-stack developer based in Mexico, specializing in custom ecommerce websites, Software devolpment and payment integration for small and medium businesses. I've built complete platforms from scratch — product catalogs, admin panels, layaway payment flows, and automated WhatsApp/email notifications — using PHP, MySQL, and gateways like Stripe, Conekta, and Mercado Pago. I also run my own retail and digital marketing businesses, so I know what owners actually need: a site that works and is easy to manage. Fluent in Spanish and English, fast response time.
