About

Who I am

Portrait of Matias Speroni

Matias Speroni

Barcelona, Spain

Junior Platform / DevOps Engineer with a software development background. I build CI/CD pipelines with GitHub Actions, publish Docker images and deploy them to a self-hosted Coolify hub secured with Pomerium Zero Trust, with isolated dev and prod environments per application.

In production since 11/2024 with .NET/C#, PostgreSQL and Python automation — promoted from intern to developer in under six months. I also build AI agents and agentic workflows, and I'm growing into infrastructure as code, Kubernetes and cloud.

Outside of work: technology, cinema and music — and travelling to discover new cultures.
