• Shaped architecture and strategy for a redesign of PayPal's Global Fraud Prevention platform, partnering with cross-domain teams.
• Lead inventor on a filed patent applying model-uncertainty measures to adaptive step-up authentication; founded a cross-team patent group within the Fraud & Data Science Centre of Excellence to help colleagues navigate the IP process.
• Mentor two engineering interns.

• Contributed to HEART, ART and ARES — IBM's open-source toolkits for adversarial-robustness evaluation and automated LLM red-teaming — including 104 commits to HEART per its public contributor record.
• Extended adversarial-robustness evaluation and defense coverage in ART across computer vision (image and video classification, object detection, segmentation) and graph-based models.
• Co-authored peer-reviewed and arXiv research on LLM guardrails, jailbreak detection and red-teaming methodology (Granite Guardian, MoJE, MAD-MAX, Attack Atlas), plus synthetic data generation and agentic-AI workload management.
• Named inventor on four published patent applications spanning federated learning, retrieval-augmented generation security, visual-content anonymisation and model-capability analysis.
• Represented IBM at IEEE ERAS 2025 (Worcester Polytechnic Institute) and AI4Media's demonstration sessions at the University of Florence.

• Led an Enterprise Ireland-funded Feasibility Study and Commercialisation project (EmPushy) in empathetic push-notifications, recruiting and managing a small team.
• Built and deployed an MVP; analysed 3M+ real-world notifications and presented findings directly to partner CTOs and R&D leads.
• Managed AWS infrastructure, GDPR compliance and IP documentation for the project.
