Back to original languageAbout Mahfoud
Expert Cloudera & AWS — Data Architect, focus on Data Platform & DevSecOps (strong AWS component)
I help data teams deliver reliable, secure, and cost-effective platforms. Playground: Cloudera CDP on AWS (and on-prem), combining AWS architecture, Terraform/Ansible, and DataOps/DevSecOps for governed, observable, and production-ready environments.
What I can bring
• Set up / modernize your platform (Hadoop → CDP 7, on-prem or AWS).
• Make it reliable & secure: CI/CD, observability & alerting, GDPR/RBAC/PII masking, IAM least-privilege.
• Accelerate time-to-data & reduce costs through automation, right-sizing, and IaC standards (“golden” patterns).
What sets me apart
• Cloudera & Hadoop: years on CDP (CDW, CDE, CML, DataHub) + HDFS, Hive, Spark, Impala, NiFi.
• AWS at scale: EKS/EMR/Glue/Redshift/S3, network/security baselines, multi-environments.
• Automation & DataOps: Terraform, Ansible, GitLab CI/CD, Python/Shell; Splunk/CloudWatch observability.
• Governance: Ranger/Lake Formation, RBAC, PII masking, GDPR evidence; international delivery (professional English, full-remote).
