I'm Kelvin Perez, a marketing technology developer focused on HTML email, web development, and automation. Nearly a decade of software engineering experience supports my work across PHP, Laravel, React, TypeScript, APIs, ecommerce, and workflow systems.

My portfolio includes responsive email examples with browser previews and inspectable HTML source, along with professional website and automation case studies. I'm building direct experience with HubSpot, Klaviyo, customer journeys, and lifecycle messaging.

Based in Fairfield, Iowa, I'm available for fully remote roles. Explore my work through the portfolio button and professional links.
