Complete web application for network equipment inventory management and interactive topology creation.
Features: Canvas topology editor with port-to-port connections, tag system (CCNA, CCNP, MPLS, VxLAN, ...), integrated configuration manager.
Architecture: Node.js backend with SQLite database (MySQL migration planned), responsive React frontend, import/export between instances.
Roadmap (WIP): Web installation wizard, multi-user collaboration (ShareLaTeX model), thick client for automatic SSH configuration injection.
Usage: Tool used daily for personal lab organization.

Reproduction of carrier architecture with MPLS backbone (3 LSRs, 2 LERs) interconnecting 2 client sites for Telnet BBS hosting.
Topology: 7 Cisco devices (2900/ISR4331), Catalyst 3650/2960X switches in CE role, logical geographical separation.
Technologies: Automatic LDP label distribution, MP-BGP sessions for VPNv4 route exchange, per-client VRF isolation, OSPF underlay routing.
Validation: MPLS packet monitoring via "packet monitor" function on switches, real-time observation of label encapsulation/distribution.
Result: Client-server connectivity established via Layer 3 VPN, BBS application accessible from remote site.

Project leader of a PING (Engineering Project) at Télécom St-Etienne. Our subject was datacenter fabric deployment with MAC learning via multicast.
Architecture: Spine-leaf topology (2 spines, 4 leafs) with 3 virtual servers, OSPF point-to-point underlay, VxLAN flood-and-learn overlay.
Redundancy: vPC (Virtual Port Channel) implementation, server bonding, ARP bug troubleshooting.
Technical challenges: Nexus 9000v image limitations affecting MAC distribution via ARP, theoretical validation of complete architecture.
Deliverables: Professional HLD/LLD documentation, sequenced Excel templates, Visio addressing plans. Evaluation: 17/20

Personal project deploying a complete virtual VxLAN fabric (2 spines, 3 TORs with two in vPC redundancy, 1 border-leaf, 1 firewall, OOB management network) based on Cisco Nexus 9300v with MP-BGP EVPN control plane.
Project methodology: Jira management (Epic/Tasks), incremental HLD and LLD documentation, initially proposing only L2VNI then L3VNI.
Automation: Creation (WIP) of two automation scripts taking Excel file parameters as input and outputting configurations (underlay and overlay) for each device mentioned in Excel. IP, link, and device management on Nautobot
Testing: Resilience testing (spine/TOR failover), vPC validation (split-brain protection, peer-link)
