Diako Harki

I am a Senior DevOps and Big Data engineer with extensive experience in automation, security operations, and Hadoop ecosystem management. I combine strong analytical skills with a proactive, collaborative approach to deliver resilient, production-grade systems.

At Vodafone I led automation and operational assurance across large-scale Hadoop environments, building Ansible control planes, PXEboot servers, and CI/CD pipelines to streamline provisioning and deployments. I automated SSL management, Python environments, and package repositories to maintain consistent baselines across thousands of nodes.

My background includes hands-on security operations, incident response, and monitoring using tools such as Splunk, Nessus, Suricata, and WAFs, plus experience building Splunk heavy forwarders and dashboards. I have also designed NiFi pipelines for large-scale data movement and fraud detection integrations with cloud APIs.

I work effectively under pressure, deliver technical presentations and workshops, and drive teams toward continuous integration, delivery, and infrastructure-as-code practices. I am committed to delivering reliable, secure, and automated platforms that meet business and client needs.
