Freelancer profile translated to English.

Description

🎯 I help large groups (banking, insurance, logistics, retail) to make their Apache Kafka platforms reliable, secure, and industrialized — from audit to operations, including team training.

What I deliver concretely:

✔ Cluster Audit: health, security, costs — with prioritized action plan

✔ Architecture & Industrialization: Topic as a Service, on-demand clusters, GitOps

✔ Performance and Cost Optimization: broker/client tuning, retention, compression

✔ Hybrid Multi-cloud: OnPrem / AWS / GCP extension via Confluent Cloud

✔ End-to-end Monitoring: Prometheus, Grafana, alerting

✔ Training for dev & ops teams, with practical labs

Typical results observed: -60% deployment time, +40% reliability, reduced infrastructure costs.
