  • Principle Architect

    2017 - PRESENT
    • Built several RESTful C# ASP.NET Web API services to allow quoting, purchase, management of insurance policies for consumers. Deployed to Azure, using EntityFramework to query and update Azure SQL Server.
    • Designed and built a pricing engine web API in C# ASP.NET accepting customer attributes and returning an insurance premium. Large static tables of data retrieved from Azure Blob and Table storage and cached in memory efficient data structures to provide ~3ms response time. The completion of the project allowed a home insurance product to launch on time following the failure of a third-party API. The Pricing Engine web API involved complex calculations that needed to be correct and very reliable. This was achieved by decomposing the calculation into components and unit testing each possibility separately, then writing code that combined these individual tests into a full regression test that could be run against the service.
    • Designed and built an inference engine web API in C# ASP.NET Core to pre-fill answers to questions based on previous answers. This enabled the technical delivery of the Homelyfe mission, "insurance made easy." Dramatically reduced the cost of quoting and marketing by replacing third-party APIs while improving accuracy.
    • Mentored junior developers.
    Technologies: REST, Entity Framework, F#, Microsoft SQL Server, Web API, ASP.NET, Azure, .NET Core, C#
  • Team Lead

    2016 - 2016
    • Developed Dynamics CRM plug-ins and interfaces via the API for extending the functionality of the core product.
    • Built REST- and SOAP-based APIs for external systems to interface with our custom Dynamics CRM data model.
    • Wrote C# integrations between Dynamics CRM and external third-party systems including Sage, Open Accounts, Exchequer, and Access Dimensions.
    • Identified technical debt and formulated an incremental plan to re-factor.
    • Sat on a company-wide technical architecture board to decide on best development tools and processes.
