What I bring to your projects:

▸ Industrialization of network security policies through Python development and REST APIs
▸ Tufin integration with internal tools: CMDB, ITSM (ServiceNow, EasyVista), IPAM
▸ Support for microsegmentation and Zero Trust projects

▸ Skills transfer and training of international technical teams

Stack: Tufin TOS Aurora · Python · REST API · Illumio · Apache Airflow · Ansible · Docker · Kubernetes · Linux · Check Point · Fortinet · Palo Alto · Juniper

I prefer long-term assignments (minimum 6 months) in BFA or large enterprise environments with critical stakes, with a technical and/or architectural scope. Availability from June 2026 (notice period ongoing).
