What I'm looking for

I seek a product-focused engineering role where I can lead frontend architecture, improve conversions, mentor teams, and build scalable, performant user experiences.

I am a Senior Front End Engineer with 5+ years building interactive, high-performance web applications using modern frameworks like React, NextJS, and Angular. I proactively lead small teams, drive cross-squad collaboration, and contribute to both frontend and backend efforts to deliver measurable product improvements.

At Consumidor Positivo I architected onboarding flows, an embeddable iframe platform with Auth0, and led a frontend rebuild that increased conversions and reduced costs while pioneering company-wide E2E testing practices. Previously, I built internal SaaS platforms at Red Ventures and single-handedly developed multilingual financial applications at Primefy, improving SEO and enabling significant payment processing.

I am a lifelong learner with strong CS fundamentals, a record of shipping scalable solutions, and a collaborative, product-focused approach that balances user experience, performance, and maintainability.
