About

Professional summary

I am a final-year Telecommunications and Services Engineering student specializing in telecommunications networks, core network deployment, and digital infrastructure.

I have hands-on experience deploying and troubleshooting 5G Standalone and 4G/LTE environments using Open5GS and srsRAN. My work includes configuring core network functions, validating end-to-end connectivity, and analyzing protocol-level traffic.

I am skilled in mobile network technologies including 5G SA, EPC, IMS/VoIP, MPLS, IP routing, SIP, GTP, S1-AP, and 3GPP standards. I use Wireshark to investigate signaling flows, packet traffic, and routing issues.

I also work with cloud and infrastructure technologies such as AWS, Docker, Docker Swarm, Kubernetes, VMware, Proxmox, Prometheus, and Grafana. I have built multi-tier cloud architectures, CI/CD container deployments, and serverless workflows.

My projects include IoT connectivity solutions using ESP32 and LoRaWAN, enterprise MPLS VPN architecture, and IMS simulation with Kamailio. I am interested in applying these skills to mission-critical telecommunications infrastructure projects in Senegal and across Africa.

I am seeking a telecommunications networks internship where I can contribute practical engineering skills while continuing to develop expertise in mobile core networks, cloud infrastructure, and digital connectivity solutions.
