The most amazing...

...system I've developed is a web-based OpenID Connect identity and access management solution used by 40,000 employees.


  • Senior Web Application Developer

    2012 - 2017
    Oregon Department of Administrative Services
    • Designed and built a single sign-on identity and access management system for 40,000 employees in more than 80 separate organizations based on IdentityServer4, OpenID Connect, and a custom group management application. This system resolved numerous security issues, reduced development time for new applications, improved the experience of users, and saved up to three million dollars in costs per year compared to alternative solutions.
    • Worked with product owners to gather requirements for rewriting a sizable back-office WebForms application. Used a lightweight approach that resulted in a collection of system context diagrams and user stories. Used an agile process to refine requirements while building a minimum viable product and then added features to this base product based on the customer's priorities. Led a small development team to implement the design using microservices, ASP.NET Core MVC, Web API, and continuous integration.
    • Developed a mobile-first, responsive web interface for an online time entry and approval application used by more than 20,000 employees and helped integrate it with the legacy mainframe payroll system via web services.
    • Performed life cycle and security analysis for a portfolio of over 30 applications built with more than half a dozen technology stacks. Identified moderate to critical security and sustainability risks and helped create documents and visuals used by the CIO to communicate the nature and scope of the identified risks to upper management.
    • Managed several Windows and Linux web and database servers.
    • Used Azure services for the rapid deployment of a proof-of-concept business intelligence portal.
    • Provided technical leadership for all other developers and training and oversight for the junior developers.
    • Initiated and succeeded in an effort to reunify the web development team and reconcile them with management after a rift between management and staff destroyed morale.
