About

A bit about who I am and what I do.

I'm a Senior Software Engineer based in Buenos Aires with over 8 years of experience designing and building full-stack applications with .NET and React. I specialize in microservices architecture, cloud platforms (Azure & GCP), message-based systems (RabbitMQ, Pub/Sub), and CI/CD automation. I work across the full software lifecycle in Agile teams with a strong focus on clean architecture, testing, and leveraging AI tooling to ship faster without sacrificing quality.

Outside of work I'm a maker and car enthusiast. I've been 3D designing and printing for years — I started out modeling in AutoCAD on an Anet A8, moved to Autodesk Inventor with an Ender 3 V2, and now run a small print farm of two Ender 3 V2s and a Bambu Lab A1 Combo. I'm also hands-on with my cars and never hesitate to get my hands dirty: I'm building a 2008 VW Touareg V8 for off-roading and a Toyota GR86 (in red) for the racetrack.
