Sales, marketing and technical support for Risk Explorer line of insurance simulation and risk analysis software (DFA). Risk Explorer is DFA software that helps actuaries to get risk modeling work done. It connects you with loss distributions, dependency models, complex reinsurance strategies over multiple years via a familiar, easy-to-learn user interface. Risk Explorer is extensible an Excel Translator, which gives actuaries the power to compile models built with Excel/VBA into fast machine code components that can be plugged seamlessly into risk models -- without custom programming by IT specialists.With two days of training, actuaries can build useful models and create system extensions. You really have to see the software and test it to appreciate its capabilities.

Responsible for building pricing and dynamic reinsurance analysis models. Priced reinsurance treaties. Performed retention and reinsurance structure analyses with brokers and other account team members. Participated in negotiations during placement process as appropriate.

Business-side technical architect of InsureMetrics dynamic financial analysis application developed at American Re. Priced reinsurance treaties. Built and supported pricing models, and guided the introduction of MATLAB as a development environment for building actuarial pricing and catastrophe analysis models and tools.

First actuarial staff member, reporting to chief actuary. Assumed control of the Holborn CLAS market share property catastrophe model, and rebuilt it after Hurricane Andrew rewrote the rules. Developed data formats for property catastrophe exposure data with new commercial model vendors. Created GIS-based analyses of exposure accumulations and deterministic "What-if" disaster scenarios to illustrate property accumulation risk. Built actuarial pricing models and one-off models for pricing innovative reinsurance products and for commutation of casualty claims.Introduced Monte Carlo simulation in financial models for the evaluation of reinsurance options. Left the firm to make what would later be called DFA software development my full-time job.

Providence, Rhode Island Area

Set up pricing and ratemaking tools as the first actuarial staff member. Built models using Turbo Pascal, then APL, and then again with Lotus 1-2-3 for succession of colleagues. Used my own tools to take over the filing of rates until other pricing analysts were hired. Worked on data quality for reporting to support pricing and loss reserving. Briefly worked on standards and support for PCs. Debugged COBOL-based actuarial reporting system, embedding with programmers for months until we had to kill the project. Created the implementation of the company's first 5-year plan and financial model using a sequence of Lotus 1-2-3 workbooks (with a macro-based handoff protocol) to accommodate the size of the model.

Personal lines pricing, pricing model maintenance (in Basic), Commercial lines rating plan development for package policies. Technical support and troubleshooting of department computing equipment (PDP-11/44).
