About

I am a Software Architect passionate about transforming complex challenges into scalable, resilient, and business-driven platforms. Throughout my career, I have designed and evolved solutions for some of the most demanding environments in the financial industry, always balancing technical excellence, architectural simplicity, and business value.

Over the years, I have built my career across different areas of the financial ecosystem. My experience includes a Brazilian wholesale bank specializing in foreign exchange, payment solutions, and financial services for businesses, followed by the global payments platform of one of Europe’s largest banking groups, where I deepened my expertise in acquiring, payment processing, and digital payment infrastructure for the Brazilian market. Today, I work at one of the largest financial institutions in Latin America, contributing to the evolution of corporate lending platforms that support both wholesale and retail banking.

This journey has given me broad experience in distributed systems, cloud architecture, APIs, microservices, event-driven architectures, transaction processing, and Domain-Driven Design (DDD), always with a strong focus on scalability, security, observability, resilience, and high availability.

Throughout my career, I have also taken on leadership responsibilities beyond software architecture, serving as a Technical Coordinator, Squad Lead, and Product Owner. These experiences strengthened my ability to connect business strategy, product development, engineering leadership, and technical decision-making. They reinforced my belief that successful platforms are built when architecture, product, and engineering work together toward a common goal.

Today, my primary focus is on solution architecture and platform modernization, while remaining open to opportunities that combine architecture, technical leadership, and engineering management. I believe technology creates its greatest impact when it connects people, processes, and business through sustainable, well-designed solutions.
