Jhonatan Carrillo, Full-Stack Developer
Full-stack developer building custom WordPress plugins, API integrations and web applications that automate real processes. Based in Barranquilla, Colombia, available for remote work.
Real solutions, not just basic websites. Four areas where I bring the most value as a full-stack developer.
Scalable web applications built with PHP, JavaScript, React and Python, with a focus on performance, security and clean architecture.
Custom plugins, WooCommerce integrations and functionality that standard plugins simply do not offer.
REST APIs that connect websites with external systems, automate processes and keep business data in sync.
Faster load times, fixed technical issues and optimized database queries for fast, stable websites.
