Brazil
Summary
👤
SeniorMario Souza is a seasoned Software Development Engineer with 13 years of experience building developer platforms, cloud infrastructure, and ML pipelines across Brazil and global teams. He has driven production readiness, CI/CD improvements, and cost-saving infrastructure changes at companies like Canva and AWS, including a $40K/month EC2 cost reduction and automation that sped regional launches from weeks to days. At NinjaTech AI he moved research prototypes into scalable ML workflows for LLMs on AWS and GCP, and added multi-GPU support to enable larger models while cutting costs. He combines low-level systems work—UDP listeners, high-availability telemetry pipelines, and event-driven Go microservices—with developer-experience improvements like IDE integrations and webhook proxies. Known for raising engineering standards, Mario frequently introduces operational checklists, IaC best practices, and observability-driven integrations that make services safer and easier to operate. He’s pragmatic and hands-on, equally comfortable troubleshooting production incidents and mentoring teams to adopt sustainable engineering habits.
