Henrique Chiuchi, UX Engineer Collaborating with U.S. digital agencies

Trusted by numerous clients to deliver user-centric designs that enhance user experiences

Building effective web solutions with purpose

With a deep understanding of user psychology and hands-on front-end experience, I bridge design and engineering to transform complex user flows into intuitive, high-performing digital experiences.

My expertise in Figma prototyping, behavioral analysis, and A/B testing — combined with multi-language coding — enables me to build solutions that align real user behavior with measurable business results.

Design that thinks and builds

I merge UX design and front-end development to create experiences that are both intuitive and technically sound.

Designing with implementation in mind, I eliminate handoff friction, accelerate delivery, and ensure every interaction looks and performs beautifully.

Versatile Front-end Development

I build responsive, performance-driven websites across platforms like Webflow, Shopify, and WordPress.

Fluent in HTML, CSS, JavaScript, jQuery, PHP, SQL, and Liquid, I create scalable interfaces that deliver both technical precision and design fidelity.

From insights to implementation

I combine research, analytics, and A/B testing with direct development adjustments to validate what truly works.

This integrated approach closes the gap between research and execution—turning feedback into measurable performance gains.
