What I'm looking for

I’m looking to work on highly complex technical challenges in Infrastructure, Development, or Architecture, contributing strategic leadership and building innovative, high-impact systems.

At C6 Bank, I lead Platform Engineering strategy and design event-driven ecosystems using NATS and Kafka. My work on architecture and infrastructure optimization reduced event platform costs 17x.

At C6 Bank, I was primarily responsible for the architecture and implementation of the DMC (Debit Mastercard) project. I developed an invoice caching system that reduced loading times by 15x and implemented the real-time purchase push service integration.

Earlier, I developed a multi-cloud management platform at C6 Bank and worked on infrastructure and systems engineering at Carrefour Comércio e Indústria Ltda., B2W Digital (Uniconsult Sistemas), and other organizations. My work has included a proprietary DNS proxy, a custom Linux distribution, and core network components for security and connectivity products.
