Actuary · Cyber Reinsurance · New York
Cyber reinsurance actuary and builder, specialising in pricing, infrastructure, and AI-native tools for complex risk.
01
I led the rebuild of RenaissanceRe's global pricing platform — and personally rewrote the entire pricing engine from scratch in Python.
I'm a full-stack developer as well as an actuary. I build the systems that model and price complex risk. At AIG I converted legacy Excel pricing tools into production Python applications, improving efficiency by 76%. While earlier in my career I won the Aviva Capital Modelling Challenge for a novel approach to risk correlation methodology in capital modelling.
My secondment as Global Cyber Actuarial Lead at RenRe's Bermuda platform put me at the centre of one of the most complex periods in the cyber reinsurance market — including the RenRe acquisition of Validus. Cyber reinsurance is among the most technically demanding pricing problems in the market today. It requires fluency across accumulation modelling, systemic risk, emerging legal frameworks, and rapidly evolving threat landscapes. It's where I've spent the last several years.
The reinsurance market still runs largely on spreadsheets and manual processes. I believe the next step in reinsurance infrastructure is bigger than submission triage and pricing recommendation workflows.

POINT OF VIEW
“Cyber risk has grown from a niche product to a material line of business for every major reinsurer in under ten years. The models are still catching up.”
The reinsurance market prices complexity through experience and judgement — and that works when risk classes are stable enough for loss data to mature. Cyber is structurally different. The threat landscape evolves faster than historical data can keep pace with, and AI is accelerating that instability while simultaneously creating an entirely new class of liability. The firms that build adaptive, data-native infrastructure today will define the market for the next decade. That window is closing.

RenaissanceRe · 2022-Present
Led a team of three to rebuild RenRe's global pricing platform from scratch — rewriting the entire pricing engine in Python, rebuilding the frontend in React, and deploying on cloud. On top of it, built an AI-enabled workflow that transformed the end-to-end pricing process across all risk classes.
RenRe · Bermuda · 2023-2024
Seconded as Global Cyber Actuarial Lead at RenRe's Bermuda platform. Strategically guided the cyber portfolio through a complex period including the RenRe acquisition of Validus. Collaborated with executive leadership on portfolio strategy and global pricing parameters.
AIG SPECIALTY INSURANCE · 2020-2022
Converted the Global Inland Marine pricing rater from Excel to a production Python application — improving efficiency by 76%. Replaced a static deductible table with a generalised regression model, improving valuation accuracy by 43%. Segmented the entire Marine portfolio in SQL and rebuilt the output, changing how underwriters accessed and interpreted their book.
Aviva · Competitions · 2019
Won the Aviva Capital Modelling Challenge, a competitive industry programme, for developing a novel methodology to more accurately measure correlations between risk factors driving capital volatility. The approach used a Dynamic Conditional Correlation model, replacing the static assumptions that most capital models rely on. The paper is published on this site.
