    Selected individual deliveries from a variety of clients:● Design, development, and deployment of an assured code import system, allowing code developed in untrusted environments to be safely imported into high-trust domains. Documented secure policies and working practices, implemented software for their verification, delivered training to stakeholders, and took the system operational.● Comprehensive security analysis of a nationally critical system, covering source code, policies, user experience, and operational practices. Lead a team to improve security posture and resilience, using the review's findings as a basis.● Migrating development processes and tooling to AWS cloud, to support the suddenly-remote workforce. Using Kubernetes as a platform that grows and shrinks as needed, each pull request is tested automatically in a clean, ephemeral environment. Developers no longer fight over shared resources, errors are caught sooner, and releases are more frequent

    Software Architect Avp
    Citi 2003 - 2006
    London
    Distributed Calculation ServerRefactoring of a critical exotics pricing engine (C++) with little supporting documentation, into a distributed system. The monolithic system was no longer able to produce satisfactory performance and was divided into distributed processes allowing calculations to run in parallel. This enabled the system to scale-out horizontally allowing the system to meet current and planned future demands. Market Data Entitlements EnforcementIntrusive changes to several key systems within the bank, to ensure that individual users are only able to view costly market data for which they have permission.Demonstrating control of market data down to individual user level saved 100,000s of pounds in fees each year.
