Network Security Engineer · Lagos, Nigeria
I design, secure and instrument networks that have to stay up: field sites on MPLS, data centre fabrics, and the Active Directory estates that sit on top of them. Most of what I build starts as a question a dashboard couldn't answer.
Enterprise Networking Network Security OT/IT Convergence Automation Python
Enterprise and data centre networking MPLS WANs linking field sites to head office, VXLAN/EVPN fabrics, and Cumulus Linux designs built around VRR and MLAG.
Network security and assessment Active Directory hardening, wireless and WAN exposure analysis, and converged OT/IT environments where availability and security tend to pull in different directions. New ideas get tested in a vulnerable-AD lab (pfSense/Snort, Wazuh, Kali Purple) before they go anywhere near production.
Automation and visibility Python tooling for diagnostics and monitoring: route classification, ARP/HSRP/VRRP pattern matching, and adaptive baselining in place of static thresholds.
Formerly LNMP (Linux Network Monitoring Platform)
FastAPI asyncio TimescaleDB Vue PrimeVue
A network monitoring platform built from scratch and running on a production network, now at v3.0. It tracks endpoint state over time and uses mean and standard deviation baselines to decide what counts as abnormal for each target. It also doubles as the backbone of a structured Python curriculum, so the code gets studied as carefully as it gets deployed.
In progress
- A reduced-package build that is lighter and faster to install
- A small on-device model (under 2B parameters) to sharpen root cause analysis, topology rendering and anomaly detection, trained on synthetic data derived from the production deployment
- GNS3 for routing, WAN and fabric experiments
- Second Mind, a headless Linux pipeline that ingests RSS feeds, summarises them with a local LLM (Ollama, Phi-3 Mini), tracks open hypotheses and sends a weekly digest
Electrical and Computer Engineering by training, network engineering and cybersecurity by trade. I write about breach analysis, lab builds and infrastructure design, with a bias toward what can be measured over what merely sounds right.
Off the clock: Formula 1, Real Madrid, and reading about how the universe actually works.
