Network security
Firewall policy, network segmentation and traffic analysis, built and broken in an isolated lab rather than read about.
Securing systems. Teaching people to spot the gaps.
Cyber Security student at CU London and freelance developer, based in Crewkerne and London. I build secure systems and teach people how they get broken.
Security is a build skill, not an afterthought.
I am a BSc (Hons) Cyber Security student at CU London, and I work freelance building web applications and testing them. Both halves point the same way: building secure systems, and teaching other people about digital safety.
That second half matters to me. A firewall rule protects one network. Showing a fourteen year old how to recognise a phishing message protects them everywhere, which is why one of my projects is an awareness game built for that age group rather than another scanner.
Right now I am going deeper on pfSense configuration, traffic analysis in Wireshark and Linux administration, alongside algorithm and data structure work in Python.

Education
BSc (Hons) Cyber Security
CU London, Dagenham. January 2025 to present. Elected Course Representative for Cyber Security.
What I work with
Two disciplines, one toolbox.
Secure systems
Cryptosystem implementation and benchmarking, and designing away from security through obscurity.
Web development
Front to back, including offline-first apps that keep user data on the device instead of on someone's server.
Systems and tooling
The environment the rest of the work happens in: Linux administration, scripting, version control and cloud.
Selected work
Network security, cryptography and web work. Everything here is on GitHub.
Enterprise Network Isolation and Firewall Hardening Lab
An isolated enterprise topology built to enforce strict segmentation. A pfSense boundary firewall routes for an Ubuntu 24.04 workstation that sits on a private internal bus with no direct path to the WAN, so every packet in or out has to pass a stateful policy at the gateway.
Phish Hunt: Spot the Scam
A cybersecurity awareness game written for 14 to 16 year olds, teaching them to recognise a phishing attempt from the things that actually give one away. Built as a team project. The hardest part was pitching real attack technique at an audience that has no security vocabulary yet.
EduSecure Cryptosystem
A sandboxed cryptosystem implementation for security research and cryptographic benchmarking, written against the principle that real data protection cannot rest on security through obscurity.
Offline-First Workout Tracker
A private training log that suggests your next session's exercises and weights from your split and lifting history. No backend and no sign-up: everything stays in localStorage on your own device.
Also built
- Delivery Route Optimizer A Travelling Salesperson solver comparing Nearest Neighbour, 2-Opt and exact brute force on the same graph. Python, standard library only.
- CPU Scheduling Simulator FCFS, Shortest Job First, Priority and Round Robin run against one workload, with a live Gantt chart and waiting and turnaround metrics.
- Inventory Management System A thread-safe stock engine with O(1) SKU lookup, a hand-written merge sort, automatic reordering at threshold and a timestamped audit trail.
What I am working on now
Security decays fast if you only read about it.
pfSense home lab
Advanced firewall configuration and automated rule management on my own isolated network.
Wireshark
Network traffic analysis. Reading what a capture actually says rather than what you expected it to.
Linux administration
System administration on the workstation and gateway hosts that make up the lab.
Algorithms in Python
Data structures and algorithm work, from graph search to scheduling to thread-safe state.
Network security and firewalls
Segmentation, stateful policy, and the gateway as the enforcement point.
Security awareness and education
Turning attack technique into something a non-technical audience can act on.
Algorithms and data structures
Graph search, scheduling strategies, sorting, and thread-safe shared state.
Student representation and project management
Running team projects, and representing other students on the course.
