About Juan Carlos

I am a web developer specializing in e-commerce and custom solutions with over 8 years of experience working with PrestaShop, Shopify, WordPress, and Laravel.

I have led integration projects between platforms, connecting online stores with marketplaces, ERPs, and CRMs using APIs and proprietary connectors. My approach combines technical robustness with business vision, helping companies scale their digital channels and optimize critical processes such as product management, orders, and data analytics.

🔧 Areas of expertise:
• Development of modules and themes for PrestaShop (1.6, 1.7, and 8.1).
• Advanced integrations with Shopify Apps (Laravel, .NET).
• REST APIs and Web Services (B2B and B2C).
• Server administration (AWS, OVH, Plesk, Ubuntu/Debian, MariaDB/MySQL).
• CI/CD with Jenkins and GitHub.
• Tracking and analytics with Matomo and Meta Conversions API.

💡 I am passionate about transforming technical complexity into practical solutions that generate real business value, always prioritizing quality, security, and scalability.

🚀 I currently help companies in the retail, cosmetics, and fashion sectors improve their digital presence, optimize their data flows, and grow in different marketplaces.
