ESI Data Center Redesign

Spine-Leaf Clos fabric · EVPN/VXLAN · eBGP underlay · 5-VRF macro-segmentation

Production-grade datacenter redesign for ESI Algiers — 2 Spines, 10 Leaves, 5 pods, fully simulated in ContainerLab with FRR and automated on Arista EOS via Ansible.

My contributions:

  • QoS strategy — 8-class DiffServ, DSCP preservation across VXLAN encapsulation, ECN/PFC scoped to Ultra Compute Pod
  • ContainerLab simulation — NTP (Chrony), DNS (Unbound), DHCP, Zabbix monitoring
  • Ansible automation on Arista EOS across the full fabric

EsiBot — Autonomous Differential Mobile Robot (team leader)

ROS 2 Jazzy · Gazebo · SLAM Toolbox · Nav2 · Raspberry Pi 4 · ESP32-CAM · React

A low-cost autonomous robot built as a TurtleBot3-class alternative using commodity IoT components. The platform replaces the TurtleBot3's LiDAR and proprietary microcontroller with a rotating ultrasonic radar (HC-SR04 + MG996R servo)

The full stack covers: 3D-printed PLA differential-drive chassis, Raspberry Pi 4 as the onboard computer (GPIO motor control, encoder odometry, sensor interfacing), ESP32-CAM for wireless MJPEG streaming, online SLAM over a 3m×3m area at 5cm/pixel resolution, autonomous point-to-point navigation with dynamic obstacle avoidance, a YOLOv8 computer vision pipeline (lane detection, obstacle proximity, traffic sign recognition), and a React web dashboard accessible from any device on the local Wi-Fi network.
