Hi, My name is Rafael Freire, a hands on brazilian software engineer with 10+ years of experience building low-latency, high-concurrency distributed systems in financial and enterprise environments. Advanced expertise in Java, Python, and Unix socket programming for mission-critical, high-throughput applications. Strong background in cloud-native architectures, infrastructure automation, and observability, with GCP and Oracle Java certifications. Currently I am exploring autonomous AI agents and GitHub Copilot–style copilots to accelerate software development and improve developer productivity. I live in Houston - TX and in my available time I usually write some cool apps that you can check in my Bitbucket and Github pages. I’m a Manning reviewer too so, I usually read a lot of tech books that I’ll suggest here in the Blog.
