Selected work

Five cases. Each one starts with a real problem and ends in production.

2026 – present · AI lesson prep · live class

ilevar

A platform for language schools where AI prepares the lesson and the homework, and a real teacher still teaches it live. I designed the system in Figma, built it in Next.js, and I stay close to the schools that use it.

Streaming Platform

A subscription streaming service with more than 500 active users. I designed and built all of it: the viewer app, the design system, the payment and access logic, and the admin panel the client runs it from.

EmailFlow Pro

Email production at Serasa Experian was bottlenecked by manual HTML coding. I mapped the workflow, designed a visual builder, and engineered the React interface that reduced campaign build time from about 80 minutes to 10–20.

02 · About

Design that ships.

I started in product design and kept moving closer to implementation. My best work happens between design and engineering — understanding the user problem, shaping the interaction, building the system behind the interface, and shipping it with the team. That's what led me to UX Engineering.

AI is part of my toolkit for prototyping and workflow automation. The responsibility stays human: make the problem clearer, the interface more useful, and the implementation more resilient.
