Tengo experiencia en la construcción e integración y mantenimiento de sitios basados en el CMS WORDPRESS. EXPERIENCIA Los últimos 6 años me he dedicado a la construcción de sitios basados en wordpress + elementor/divi + woocommerce, todos en diferentes perfiles de servicios que van desde espacios corporativos y blogs personales, pasando por tiendas virtuales a plataformas educativas de nivel medio. Para la configuración de plataformas educativas he utilizado componentes como: learndash, learnpress, tutorlms, sensei lms. ¿PORQUÉ CONTRATARME? - GARANTÍA: Ofrezco garantía post entrega que va de 10 a 30 días con cada uno de mis trabajos realizados, sea desarrollos a medida con PHP + LARAVEL o aquellos construidos con WORDPRESS. - 24/7: trato de estar activo en freelancer.com los 7 días de la semana en horarios (GMT-4), pero me ha tocado atender en la madrugada a clientes tanto conocidos, como interesados en proyectos de países con horarios diferentes al mío. - TRANSPARENCIA: Conmigo encontrará seriedad a la hora de dar respuesta a su necesidad, no voy a comprometerme en algo que no puedo cumplir, prefiero decir que no puedo hacerlo a decir que si y hacerle perder el tiempo/dinero con algo mal elaborado e incompleto. Les invito ahora a leer los comentarios que más de 250 clientes me han dejado y donde la mayoría suele recontratarme, reiterando la garantía de mi responsabilidad y transparencia. mai puțin
