PORTRAIT TO BE ADDED

I work at the intersection of cyber security and machine learning. My MSc dissertation explores adversarial training for deep-learning intrusion detection on the Controller Area Network (CAN bus), the nervous system of every modern car, using the CICIoV2024 dataset and techniques from the Adversarial Robustness Toolbox.

Before Plymouth, I built NetEAGLE, a Raspberry Pi-based network gateway combining a Flask API, mobile app, Nmap, UFW and Suricata IDPS into a single home-network defender. Earlier still, I served as a Cyber Security Engineer Executive at Union Assurance PLC and an Associate Engineer at Lanka Communications.

When I'm not reading papers I'm cataloguing antiques in The Reliquary, documenting Sri Lankan and global recipes in Rampe, and refining the database that powers this site.

Selected Work

Four projects that explain how I think.

Each one started as a research question, not a feature list. That is the difference that matters.

Research2025· In Progress

MSc Dissertation: Adversarial Training for Deep-Learning IDS in the Internet of Vehicles

Hardening neural IDS against FGSM and PGD attacks on the CAN bus.

Master's dissertation investigating whether adversarial training can make deep-learning intrusion detection systems robust against evasion attacks on the Controller Area Network (CAN bus), the primary in-vehicle communication backbone. The work uses the CICIoV2024 dataset and compares a 1D-CNN baseline against a Random Forest baseline under Fast Gradient Sign Method (FGSM) and Projected Gradient Descent (PGD) attacks, then evaluates a Multi-Strategy Adversarial Training defence implemented via the Adversarial Robustness Toolbox (ART).

NetEAGLE

Raspberry Pi network security gateway with mobile control plane.

Final-year BSc project: a self-contained home network security gateway built on a Raspberry Pi 5. NetEAGLE combines a Flask-based REST API, a companion mobile application, and a hardened Linux stack (Nmap for discovery, UFW for firewalling, and Suricata for intrusion detection and prevention) into a single device that gives non-technical users meaningful visibility and control over what's happening on their network.

The Reliquary

Living archive of antiques, books, and historical objects.

Personal digital reliquary: a curated, research-backed catalogue of antiques and historical items. Each entry is documented with provenance, condition, valuation notes, and reference material. The site is the public face of an extensive private Notion database and showcases how a careful schema, oxblood-and-cream visual language, and editorial writing turn a personal collection into something genuinely useful. Curation, schema, and copy mine; site code written by Perplexity, Claude Opus 4.7, and Claude Sonnet 4.6 under direction.

Other rooms in the same house.

Two long-running personal projects that live next to the engineering work, and quietly inform it.

AntiquesLive

The Reliquary

Living archive of antiques, books, and historical objects.

A curated, research-backed catalogue of antiques and historical items, each one documented with provenance, condition, valuation notes, and reference material. Oxblood and cream visual language, inspired by leather-bound archives. The public face of a much larger private database.
