Hi. I’m a Senior Backend Engineer with 15+ years of experience, specialized in the Java ecosystem and high-scale systems. Recently, I’ve been working as a contractor for Apple (Ad Serving) and Eron International, focusing on performance tuning, fraud detection architecture, and cloud migrations.

I have a strong background in distributed systems and DevOps (K8s/AWS/GCP), and I’m also an IT Professor at UTN. I enjoy solving complex concurrency issues, optimizing database performance, and mentoring teams.

Looking for a Senior Backend role in a remote-first company where I can contribute to core architecture and scalability challenges.
