• Network engineering: from defining the LAN/WAN network architecture to optimizing and securing it • Technical project management (installation, migration, etc.) as well as implementing developments in our clients' network and security infrastructures • Drafting and validating technical architecture files (DAT) • Auditing the network and security infrastructures of certain clients • Setting up Pentest environments via Kali Linux - Scope: Networking, Firewalling & CyberSecurity. - Technologies used: Palo Alto, Cisco ASA, HP, Nortel, Checkpoint, F5, ShrewSoft, pfSense, Kali Linux, etc. - Methods adopted: Pentesting, DDOS, Scripting, IP Spoofing, SSO, Port Scanning, Payloads, MITM, ARP Poisoning, Sniffer, etc.

Carrying out various missions throughout France, the aim of which is to gain more experience in support and computer networks: - Installation and configuration of routers, and migration of lines. - N2 support, monitoring of incidents of active equipment (Routers, Switches, Terminals) and modification and improvement of configurations. - Installation, maintenance, support and service to users in IT. - Management of access rights, for machines and users. - 1st and 2nd level technical support on micro-computing and network-analysis products. - Resolution of incidents and breakdowns using the common tool of IT Global (Service Now). Missions developed in premises and Datacenters located in: Lyon, Paris and Volx. I was able to considerably improve my English thanks to an internationally oriented work environment, (recurring exchanges with a team of engineers located in Denmark).

End-of-studies internship in the IT department, network and supervision division. 3 projects: 1- Develop the network equipment supervision platform (managed under hyper-v) in order to optimize its operation, facilitate its operation and developments, optimize alert management, standardize procedures and study the implementation of new features: • Incident monitoring of active equipment and configuration improvements • Categorize and prioritize alerts • Identify the right level of alerting • Reporting • Integration of plugins and packages • Inventory of HS resources • Organize the upgrade, etc. [The platform monitors several thousand network objects with alerts in the event of major/critical events and also monitors the network infrastructures of DataCenters, sales areas, warehouses, headquarters, etc.] 2- Qualify an IP addressing plan management solution: • Set up a technological watch on IP addressing solutions by studying the existing market, with the aim of evolving towards an IP address management tool that will be used by several internal teams. • Study of paid and open source IP addressing solutions. • Benchmarking. • Selection and implementation of a tool. • Commissioning, etc. 3- Integrate and optimize the operation of warehouse equipment in a new backup tool. Concept of cross-functional management used and developed. Technologies used: Centreon, phpIPAM, NetBox, NIPAP, GestióIP, IPAM, TeemIP, GLPI and BT Diamond IP, Linux, Bash, PHP, SQL, Perl, LDAP, VSS, Check Point, NetScaler, NCM (Network Configuration Manager). Mastery of the supervision tool: "Centreon" Mastery of the IPAM solution: "phpIPAM" I was able to acquire skills related to security (access to active equipment, implementation of certificate authority), and an ability to manage incidents in production environments.

Carrying out various missions all over France, the aim of which is to gain more experience in computer networks that can enrich my abilities to handle practical cases in the field. During these missions carried out in different cities in France, I was accompanied by a network engineer, who guided me throughout the service: • On-Site Pre-Work • Rack Elevations • VIS Server Install • Port Blocking • Services Rack Clean • Network Rack Clean • Decibel Testing • Miscellaneous Tasks • Photo Checklist • On-Site Post-Work

Initiative internship: ● Study and development of hybrid fixed access network architectures (optical and copper) for increasing throughput. ● Development of a QoS-QoE correlation model (analyze data collected from the OTN network, apply the different Data Mining tasks such as Clustering, Pattern Discovery, etc.). ● Implementation of test benches. ● Creation or update of technical and commercial documentation for the Datacenter service and creation of Templates for users.

As part of my first internship at an engineering school in the "Destock Sport" store, I was required to perform several functions: ● Reception of customers, listening, fault finding, computer data entry ● File monitoring: customer telephone interviews, computer updates ● Storage: reorganization of the store's stock ● Merchandising: Shelving ● Familiarization with the works exhibited ● Maintenance of a network through customers on the internet ● Management of product stock and level control ● Packaging and conservation ● Delivery of products

End of studies project within the National Agency for Computer Security as part of obtaining an applied degree in computer networks and services. The proposed solution is based on the development of integrated virtual firewalls whose main role is to control all data circulating in the internal and external network in order to increase the level of control and thus the level of security. These two firewalls ("ASA 842" / "PfSense") are developed in an emulator called "GNS3", its role is to group and manage all the equipment of the computer system and thus thanks to the international guide "CISCO SAFE", we can apply the design methods for corporate security. ("GNS3" is an open-source tool that allows you to create virtual networks. Initially created to allow network engineers to learn how Cisco equipment works, it was later extended to allow the study of other types of equipment. In GNS3, these hardware devices are simulated, meaning that you can perform almost the same operations as on real equipment but without having to acquire them.). On the other hand, there was an evaluation of open source Firewall solutions and the validation of the "Pfsense" product. I participated in the deployment of the solution in almost 50 schools and the customization of the "Pfsense" management interfaces as well as missions in Audit and IT security. -Technologies used: Linux, PfSense, Bash, LDAP, LAN/WAN, TCP/IP, PHP, CSS, CISCO PAQUET TRACER, GNS3. Mastery of the tool: "PfSense"
