I'm a Senior Software Engineer based in Ciudad Juárez, Mexico, working remotely with US companies. Over the past decade, I've built and scaled user-facing platforms for major consumer brands, including a top-50 US childcare network and Expedia's Hotwire.
I don't just write code; I bridge the gap between engineering decisions and business impact. A slow website isn't just a technical debt—it's a leak in your revenue funnel. I specialize in plugging that leak through targeted Core Web Vitals optimization, micro-frontend architecture, and AI-assisted development workflows.
