Freelancer profile translated to English.
Back to original languageAbout Jossar
DevOps with concrete expertise in high-constraint production environments: Setup and monitoring of a swarm cluster ~1700 IoT edge devices (Docker Swarm, 4G connectivity) and GKE clusters, with a complete observability stack (Grafana, Mimir, Loki, Alloy, Zabbix) to ensure resilience and real-time visibility.
My daily routine: infrastructure automation with Ansible AWX and OpenTofu (IaC), CI/CD pipelines on GitHub Actions, IoT messaging management (EMQX/MQTT), container orchestration (Portainer, Docker Swarm). I design alerts-as-code (PromQL, mimirtool) and work on network reliability and compliance (IEC 62443) topics.
Before DevOps, I spent 4 years as a Full Stack developer (Vue.js, React, Node.js, React Native), which allows me to communicate effectively with development teams and design CI/CD pipelines truly adapted to their needs.
Available for infra reinforcement missions, cloud migration, observability setup, or Ansible/Terraform automation.
