About

Previously a Senior Software Engineer at Scale AI, focused on the Enterprise platform and observability. I was the inaugural Founding Software Engineer at Context.ai, where we built a pioneering product analytics and evaluations platform for LLM applications. Context.ai joined OpenAI in April 2025. Over five years of software development, I’ve led a critical Reserving Calculation Engine integration at global insurer Hamilton Insurance and engineered sophisticated anomaly detection models for cyber-physical security at Exalens. An elected Academic Scholar at Trinity College Dublin, I graduated Top of Class with an Integrated Master's in Computer and Electronic Engineering.
