Turning complexity into business value

Software Architect and Cloud Specialist with 7+ years of experience designing and sustaining mission-critical distributed systems. Focused on transforming technical complexity into real business value, I work with cloud-native architectures on AWS, process automation (IaC), and a FinOps culture.

Driven by continuous learning and innovation, I apply Platform Engineering and DevOps practices to build secure ecosystems, remove operational bottlenecks, and accelerate delivery and efficiency across multiple engineering teams.
