Back to original languageAbout Abdessamad
Data & Platforms Engineer | Mainframe Observability · AWS Cloud · Python
Engineer with 5 years of experience in critical banking environments, I design and operate large-scale monitoring, data collection, and observability platforms — particularly on Mainframe z/OS and Linux infrastructures.
I master both the Mainframe ecosystem (JCL, CICS, DB2 z/OS, SMF, Dynatrace, BMC AmiOps) and modern data and cloud technologies (Python, AWS, Docker, Grafana, Elasticsearch, Airflow). This dual expertise allows me to work on legacy-to-cloud migration projects, data integration, or the implementation of observability solutions in high-availability contexts.
What I bring concretely:
• Design and deployment of data pipelines (SMF, ETL, REST APIs)
• Implementation of monitoring stacks: Grafana, Dynatrace, Kibana, Prometheus
• Automation via Python, Ansible, Jenkins, CI/CD
• Analytical visualization and reporting (Cognos, Grafana, Kibana)
• Experience in Agile environments, ServiceNow, Clarity
Certified AWS Data Engineer Associate, AWS Cloud Practitioner, and Dynatrace Performance Expert.
Available for consulting or execution missions in the fields of: Data Engineering · Observability · Mainframe Infrastructure · AWS Cloud.
