About me

My name is Antonia Bonfitto, I am a Senior Software Engineer with 6+ years of professional experience. I specialize in Backend and Cloud Architecture, with a focus on Kubernetes and AWS.

  • Backend Engineering

    I design APIs, microservices and distributed systems that are maintainable, performant and observable.

  • Cloud Architecture

    I leverage AWS and Kubernetes to implement scalable systems, automating them with Infrastructure as Code

Experienced in multiple tech stacks. I approach technology with pragmatism and choose the most efficient tools for each business challenge. Autonomous and results-oriented.
