I help agencies, startups, and fast-moving teams turn fragile websites into fast, measurable, and scalable growth engines. I combine the precision of performance engineering with the empathy of user-centered design to create sites that not only load fast but also drive conversions, retention, and trust. Coming from years of hands-on experience building, fixing, and optimizing websites across industries (from restaurants and entertainment to crypto startups) I’ve seen how technical debt, poor accessibility, and slow performance silently drain business results. My mission is to reverse that. By blending technical audits, Core Web Vitals optimization, and accessibility-driven architecture, I translate engineering precision into business outcomes: faster sites that convert better, accessible experiences that reach more users, and maintainable systems that scale with less friction. Each build I deliver is modular, verifiable, and engineered for measurable growth.
