Implementation of new architectures and IT management for clients (Paylib, Stef, Decathlon, h2o...)

• IT management for over 10 clients.

• Security referent for Kubernetes and cloud (Trivy, starboard, developer awareness…)

• Consulting on GCP cloud: Study, security, HA, DRP…

• IT management and client support for Kubernetes clusters

• Define client needs and implement new Cloud architectures using the latest market trends:

◦ Deployment of client infrastructures (GKE, network, sqlcloud, Elasticsearch …) on GCP via Terraform

◦ Continuous deployment of infrastructures via ArgoCD, Argo Workflow, Helm, and Git

◦ Monitoring of client infrastructures via: Grafana, Alert Manager, Prometheus, InfluxDB, Opsgenie…

• Implementation of internal solutions to improve client management.

• Migration of Paylib PF including OpenShift to Kubernetes RKE (estimated cost optimization of - €300k/year)

• Documentation and knowledge transfer

• Migration from vSphere to Proxmox

• Implementation of secure and replicated centralized storage in a CEPH cluster

• Migration of CentOS 6 servers to CentOS 7

• Centralization of logs using Filebeat, Elasticsearch, and Kibana

• Installation and configuration of access management via Ansible and The Bastion

Environment: GCP, Kubernetes, GKE, Docker, Terraform, Helm, Shell, Git, MongoDB, Elasticsearch, Apache, Cerebro, Grafana, InfluxDB, Telegraf, Prometheus, ArgoCD, Ansible, Redis, Logstash, CentOS, Debian, FTP, HTTPS, DNS, Starboard, Trivy, Gatekeeper…

Implementation of new architectures and improvement of existing architecture

• Opening of a new service point on GCP for our API management:

◦ Relieve the AWS service point (1.1 Billion calls/week)

◦ Write Terraform and shell code to provision the new infrastructure

◦ Ensure high availability between 2 cloud providers

◦ Be closer to our users

• Design and implement our monitoring system to improve our alerting system and for better scalability.

• Full support of the infrastructure in the Cloud (AWS, GCP), performing upgrades, maintenance, and deployments in all environments

• Documentation

• Modification of Elasticsearch architecture: separation of roles, performance improvement (30 TB of data across 3 continents and 2 cloud providers)

• Migration of the Elasticsearch cluster to SaaS (Aiven)

• Participation in the migration of API management (Gravitee) from traditional VMs in the cloud to Kubernetes.

• Patching machines via Rundeck and bash scripts

• Participation in the improvement of the DRP plan between different clusters and cloud providers

Environment: AWS, GCP, Kubernetes, GKE, Docker, Terraform, Helm, TheForeman, Shell, PagerDuty, Git, MongoDB, Elasticsearch, Apache, Cerebro, Grafana, InfluxDB, Telegraf, Gravitee, API, JAVA, Redis, Logstash, CentOS, RHEL, FTP, HTTPS, DNS.

Creation of new platforms for our major clients.

• Contributions to identifying development needs (annual turnover ≈ €300M)

• System and database administration

• Operations monitoring, project planning, execution tasks within deadlines

• Coordination of stakeholders

• Organization, Implementation of processes and procedures

• Assistance in resolving encountered problems

• Definition of improvement areas for delivered services

• Creation and centralization of client documentation
