Hello đź‘‹
I take care of highlighting your applications by making them as available as possible. 💯​
âś… Systems and network infrastructure:
- Creation of your resources via IaC (Terraform / Terragrunt)
- Cloud (AWS, Azure) or on-premise (VMware, Proxmox)
âś… Deployment and maintenance of your applications:
- Automation of deployments (ArgoCD, Ansible...)
- High availability of your services
- Updating your dependencies (backward compatibility)
âś… Security and alerts:
- Compliance with security standards (OWASP, ANSSI)
- Alerts and dashboards for your applications
Focused on large accounts (SNCF, Bouygues Telecom...), I also adapt my expertise to smaller environments (Kayrros, Doxallia) by using a universal methodology if necessary, ITIL.
