Network Security Engineer
I secure enterprise networks for a living, deploying and managing Sophos and Fortinet estates across 10+ client networks, and I build labs that test how attacks get past defences. MSc Cybersecurity with Distinction, Wrexham University.

PL1 → PL2: detection unchanged (TPR 97.0%), false positives doubled (1.0% → 2.0%)
Tested ModSecurity CRS 3.3.8 at Paranoia Level 1 vs PL2 against structured SQLi and XSS payloads in a Docker-based reverse-proxy testbed. Every observed difference traced back to threshold arithmetic rather than additional rule logic: a practical argument against blindly raising paranoia levels in production. Built as my MSc dissertation (Distinction).
Featured · Detection Engineering
Rediscovered a boolean-blind SQLi bypass with a leftanti KQL join: HTTP 200, zero rule hits
Detection lab that ingests ModSecurity and NGINX logs into Microsoft Sentinel via the Azure Monitor Logs Ingestion API and surfaces attacks the WAF let through. Built on a custom dual-table schema, Data Collection Rules, a scoped Entra app registration, and Python log parsing; validated against the dissertation dataset.
Linear SVM vs LightGBM vs a PyTorch MLP for static PE malware classification on EMBER 2018. LightGBM led with F1 0.9474 and ROC AUC 0.9892; ranking stability verified across two stratified subsets.
Logistic regression, random forest, and XGBoost on the UCI Heart Disease dataset, evaluated with stratified 5-fold cross-validation, calibration curves, ROC analysis, and McNemar's testing.
Python scanner that enumerates links and forms on target web applications and tests for reflected XSS. Built and tested against Metasploitable in an isolated lab.
Checks passwords against the Have I Been Pwned Pwned Passwords API using k-Anonymity, so no plaintext password ever leaves the machine.
Web scraper that extracts top-voted Hacker News stories, filters by vote threshold, and delivers a clean, ranked daily digest by email.
Flask backend with a markdown-powered blog engine, CSRF-protected contact form, and rate limiting. Deployed on Render.
I started out in IT support in Lagos, troubleshooting Windows estates and Active Directory, then moved into network security engineering, deploying and managing Sophos and Fortinet environments for enterprise clients in financial services, oil and gas, and telecoms.
In 2026 I completed an MSc in Cybersecurity at Wrexham University with Distinction. My dissertation put ModSecurity WAF rulesets under empirical test in a Docker-based reverse-proxy testbed, and I've since extended that work into detection engineering with Microsoft Sentinel. Alongside the degree I've worked through PortSwigger's Web Security Academy and built ML-based malware detection models.
I'm available immediately for network security, security operations, and junior security roles across the UK: on-site, hybrid, or remote.
Away from the keyboard: gaming, basketball, and chess.
