Hello! I’m Hafeez Ur Rehman, a results-driven DevOps Engineer with 12 years of IT experience, including 7 years in DevOps/SysOps and 5 years in Network Systems. I lead agile teams in deploying and managing multi-cloud applications on AWS, GCP, and Azure, with expertise in IaC, CI/CD, Kubernetes, and cloud-native architecture. I also design and implement MLOps pipelines for model training, versioning, and deployment, and I focus on security hardening, disaster recovery, and cost optimization to deliver reliable, high-performance systems. I thrive in fintech, healthcare, e-commerce, and gaming environments across Europe, the United States, and Canada, collaborating with cross-functional teams via Slack, Teams, Jira, Confluence, and GitHub/GitLab.
Passionate about building scalable, secure, and observable distributed systems, I continuously pursue excellence in automation, testing, and performance tuning to reduce latency and costs while improving reliability.
