Product Ops Lead at Nubank | FinOps & Cloud Financial Management Leader | AWS Cost Optimization

São Paulo, Brazil

About

As a passionate advocate for cloud financial management, I am constantly transforming cloud cost challenges into strategic advantages with an eye on scaling business operations and ensuring that every dollar spent in the cloud was a dollar well-invested. Today, as Product Ops Lead at Nubank, I’m fortunate to lead initiatives that drive real, measurable change in FinOps and Cloud Financial Management. At Nubank, I have shaped the renowned AWS Cost Champion program, a flagship initiative that has not only optimized cloud spending but also fostered a cultural shift toward greater financial accountability across the organization while creating new career opportunities . My role is a blend of strategy, technical acumen, and leadership — where I collaborate with teams to tackle cloud cost inefficiencies head-on and help them realize the strategic value of these investments. I’m driven by the belief that cloud financial management is not just about cutting costs—it’s about optimizing investments for growth. Through data, collaboration, and innovation, I help organizations turn their cloud infrastructure into a competitive edge. With extensive end-to-end experience in small and large-scale agile transformations, I’ve played key roles from project lead to product owner and rollout coordinator across multiple projects using the SAFe framework. I’ve also hosted and spoken at several industry events on open banking and identity. A proud Berliner living in São Paulo, I hold a Master’s degree in International Business Administration (M.Sc.) from Frankfurt and León. Fluent in German, English, Portuguese, and Spanish, with basic French, I thrive in multicultural environments and value the power of diverse perspectives. I’m constantly seeking to connect with forward-thinking professionals who are also passionate about making cloud financial management more efficient, scalable, and impactful. Let’s connect if you’re interested in collaborating on innovative solutions that drive real business value!
