Orlando Arnosa

FULL STACK DEVELOPER

I bridge business, marketing, and technology to craft scalable, high-performance web experiences that drive growth.

About

I'm a full-stack developer with a passion for building scalable, high-performance websites that solve real business problems. I specialize in JavaScript and TypeScript ecosystems, creating digital experiences that are fast, maintainable, and integrated with the tools and workflows teams rely on.

At Mosaic Companies, I lead the development of ecommerce and marketing websites across platforms like Shopify, WooCommerce, and WordPress. I work closely with cross-functional teams to ship features that drive conversions and improve operations. This includes building custom UI components with React and Next.js, optimizing SEO and performance, and syncing product data through custom APIs, ERP integrations, and backend automation.

My work blends practical frontend development with backend logic using Node.js, Express, and SQL. I've delivered internal tools, custom apps, and automation workflows that streamline product launches, manage complex data, and improve site reliability.

Outside of work, I'm a proud girl dad to a wild toddler. When I'm not debugging something, I'm usually chasing her around the house or sneaking in a quick gaming session.
