Back to original languageAbout Guillaume
Freelance actuary specializing in life reinsurance and actuarial modeling, I support insurance and reinsurance companies on high-stakes topics of pricing, valuation, reserving, and regulatory compliance.
I intervene in particular on:
• US GAAP LDTI: modeling, results production, analysis, documentation, and stakeholder support (Europe / North America)
• Solvency II: valuation, calculation process, chain optimization, and fast-close approaches
• AXIS model development and maintenance: longevity, disability, critical illness, reinsurance.
• Model migration (e.g., MoSeS → AXIS): scoping, redesign, testing, comparisons, stabilization, and go-live.
• Reinsurance pricing & product development: treaty structures, risk bases (mortality / disability), experience analysis, renewals, and pricing activity management.
Accustomed to working in demanding environments, I combine a rigorous approach (governance, traceability, documentation) with a business focus (results readability, pedagogy, decision-making). I also have experience in mentoring and coaching teams on the use and scaling of actuarial models.
Tools & environments: AXIS (expert), SAS / VBA, valuation and reporting repositories.
If you are looking for a ready-to-use profile, I can provide reinforcement, project management, or ad-hoc expertise.
