Your instructor, from day one to the last day
I am Mathieu ELIE, Elasticsearch trainer and Elastic Stack (ELK) instructor. I deliver your course myself, from the first day to the last. Since 2016, I have delivered over 160 courses across the whole Elastic platform: search, administration, data ingestion, Kibana, observability, security / SIEM and machine learning.
A PRACTITIONER
- I spend 50% of my time consulting, on clusters running in production.
- In class, I share what really works (and what breaks) in production, not just what the documentation says.
ELASTIC CERTIFIED
- Elastic Certified Engineer since September 2025 (verify the certification).
- I have taken the exam and can help your teams prepare for it.
UP TO DATE
- Courses up to date with Elasticsearch 8.x and 9.x: ES|QL, vector and hybrid search, data streams...
- 100% Elastic since 2016: I follow the stack as it evolves, release after release.
HOW A COURSE WORKS
Practical courses, designed so your teams leave ready to work.- 50% theory, 50% practice. Each module ends with a lab on a realistic dataset, with solutions.
- In-house or public sessions, on site or remote, in English or French.
- Flexible duration to fit your constraints: we adjust lab time and the level of detail.
- Customizable content: I can adapt the course to your context and add a consulting part on your own data or cluster.
- Training materials: PDF materials and the code for all hands-on labs.
MY COURSES
One course per use of the stack, with no overlap between them.- Elasticsearch training (2 to 4 days): mapping, Query DSL, relevance, aggregations, ES|QL, vector search.
- Elasticsearch administration (2 to 4 days): deploy, secure, monitor and upgrade a production cluster.
- Elastic Stack ELK training (2 to 5 days): Elasticsearch, Logstash and Kibana, from install to monitoring.
- Kibana training (3 to 4 days): Discover, KQL, Lens, dashboards, alerting.
- Elastic Observability training (3 to 5 days): logs, metrics and APM traces with Elastic Agent and Fleet.
- Elastic SIEM / Security training (3 to 5 days): ECS, detections, alerts and investigation.
- Elastic machine learning training (2 days): anomaly detection, forecasting, data frame analytics.
Mathieu is a "real" ELK expert. He has a genuine mastery of the product, combined with excellent communication that makes him a great teacher whatever the level of the person he is talking to. He is also very responsive and efficient in delivering the topics he is responsible for. (translated from French)
