What I'm looking for

I'm looking to lead architecture and backend engineering for high-scale cloud platforms, helping teams build reliable distributed systems, improve delivery through DevOps, and apply AI to meaningful operational and business challenges.

At Mercado Libre, I led the architecture and implementation of Meli+ Mega integrations with Netflix, Apple TV, and Globo for launches across Brazil and Mexico. I also built agentic AI workflows for business-data analysis and predictive diagnosis of alerts and anomalies.

I've spent more than 15 years designing scalable distributed systems and cloud platforms for fintech and e-commerce. My work spans .NET, Azure, microservices, distributed databases, event-driven systems, observability, and technical leadership.

At Sistecredito, I led enterprise architecture, established engineering standards, created the QA and DevOps functions, and designed the second version of the core credit management platform. I introduced Azure-based microservices patterns and expanded transactional capabilities through external payment integrations.

Earlier, I led critical architecture projects at ARKIX and built business-critical .NET applications at Aleriant. I enjoy turning complex business requirements into scalable architectures, guiding teams through delivery, and improving engineering quality through practical technical governance.
