About

Hi, I’m Marcelo Barbosa, a software engineer with 20+ years of experience building APIs, CLIs, and Linux services. I have deep cloud experience across AWS, Azure, and GCP, and I enjoy turning complex problems into reliable, scalable solutions.

In recent years I’ve specialized in DevOps/SRE/Platform engineering—automating infrastructure, improving observability, and enabling multi-cloud product offerings. I collaborate well in teams and love mentoring others to ship high-quality software quickly.
