Modern Marketing in Encinitas's Leucadia district is a full-stack development and digital marketing agency founded in 2015, building e-commerce websites and custom applications from its North Coast Highway 101 office along the 101 corridor. E-commerce development spans WooCommerce, Shopify, BigCommerce, and Magento platforms with integrated payment gateways supporting Apple Pay, PayPal, Google Pay, and credit card processing — digital storefronts built for North County retailers and food brands, including Better Buzz Coffee Encinitas. The agency maintains an 11-to-50-person team handling WordPress development, iOS app design, Webflow builds, SEO, analytics, and social media management for clients across Orange County, San Diego, and international markets. Branding and creative design services extend from logo development and visual identity systems through digital advertising campaigns, providing full-lifecycle marketing support from brand launch through ongoing performance optimization. Full-stack development capabilities include custom PHP, JavaScript, and database architecture for enterprise-level web applications, serving the same North County business ecosystem anchored by Dudek and other Encinitas-based enterprise clients. Highest-complexity e-commerce builds involve multi-currency checkout configurations, tiered shipping-rate calculators with real-time carrier API integrations, automated inventory-sync modules connecting Shopify or WooCommerce to ERP middleware, and PCI-DSS-compliant payment architectures.
