* Performed 5G NSA field testing and optimization, providing real-time KPI analysis for accessibility, retainability mobility, integrity and throughput performance. * Diagnosed and escalated EN-DC LTE anchor configuration issues, restoring 5G service availability in affected areas. *Identified serving cell dominance and overshooting scenarios, recommending antenna tilt adjustments to improve coverage balance and user experience. * Investigated throughput degradation cases using field measurements and KPI correlation, enabling fault isolation and resolution. *Conducted multi-layer analysis (LTE + NR) to detect coverage gaps, interference, and performance bottlenecks.

Designed and maintain a fully containerized 5G Standalone Core lab (Free5GC + UERANSIM) on Ubuntu, with all 10 network functions (AMF, SMF, UPF, PCF, UDR, UDM, AUSF, NRF, NSSF, CHF) running as independent processes. Configured per-subscriber AMBR policies via MongoDB PCF data, implemented multi-slice registration across two network slices (SST:1 SD:010203 and SST:1 SD:112233), and conducted deliberate NF failure isolation testing to observe core behavior under AMF, SMF, PCF, and UDR failures. Integrated Prometheus and Grafana for real-time per-subscriber monitoring, and automated infrastructure provisioning using Ansible, Terraform, Jenkins CI/CD pipelines, and AWS services including VPC, ALB, ASG, EventBridge, and Lambda.

* Conducted cluster and SSV drive tests across Airtel and MTN deployments in Lagos, Nigeria on ZTE equipment, using TEMS Pocket with customized scripts, ensuring consistent log collection and KPI analysis. * Conducted 5G/4G drive tests (cluster + SSV) and stationary logs, identifying performance gaps and network improvements. * Resolved vendor issues by extracting critical 5G HO/fallback events that field engineers had missed. * Prepared and validated reports for ZTE, Ericsson, and Nokia projects, ensuring 100% vendor acceptance. * Provided remote technical guidance to field engineers; analyzed logs and identified improvement opportunities. * Investigated and resolved customer complaint clusters, improving throughput efficiency by 95%. * Performed RAN swap correction analysis for misaligned sectors, restoring coverage accuracy and ensuring proper service continuity. * Mentored junior engineers on optimization workflows, drive test methodology, and reporting standards. * Performed back-office KPI analysis covering Accessibility, Retainability, Mobility, and Integrity, identifying degraded cells and producing optimization reports for network improvement.

* Conducted an SSV on 4G, 3G and 2G technologies on the MOOV AFRICA project. (Ericsson equipment) * Carried out corrections on swapped sectors * Carried out static tests with special attention on Carrier Aggregation of the L2600 Band * Provided real time feedbacks to the back office for immediate optimization

* Diagnosed causes of accessibility, mobility and retainability issues on MTN sites * Diagnosed causes of poor throughput. * Conducted a cluster (POLQA) test for quality assessment (MOS) of mobile networks on MOOV AFRICA between the cities of Cotonou and Ouidah * Attended to customer complaints and resolved same on all MTN sites in the Republic of Benin.

* IT systems and infrastructure support. * Assembled and configured computer systems; provided hardware and software support for SMEs and individuals.
