What I'm looking for

I am looking for a role that fosters innovation, encourages team collaboration, and offers opportunities for professional growth in mobile technology.

As a Senior Flutter Engineer and Mobile Tech Lead, I bring over 2.6 years of professional experience focused on architecting and delivering high-performance cross-platform applications. My expertise lies in Clean Architecture, modular design, and offline-first strategies, which I have successfully implemented in various projects. I have a proven track record of leading mobile teams, defining architectural strategies, and mentoring engineers to elevate technical standards.

In my current role as Lead Software Engineer at Construtor de Vendas CRM, I spearhead the mobile strategy, focusing on scalable architecture and automation. I designed an automated CI/CD pipeline that significantly reduced manual setup time and enabled the scalable delivery of customized apps. My commitment to performance optimization has led to a 60% reduction in load times for hybrid applications, and I actively contribute to the Flutter community through technical articles and knowledge-sharing initiatives.
