Our mission is to empower the next generation of secure digital business. By eliminating passwords and creating a fundamentally secure Chain of Trust™, our customers are able to increase business velocity, implement new business models, and reduce operating costs.• Architect of policy system, Beyond Identity's central platform for all auth and identity operations    ◦ Our policy engine is the primary differentiator in the eyes of customers    ◦ Developed initial vision and guided formation of product team    ◦ Platform modeled in Haskell, and MVP implementation leveraging graphQL and osquery• Established mobile and desktop application architecture for flagship authenticator app    ◦ Based on sound composition and effect tracking principles    ◦ Emphasis on correctness and trivial testability to an area of code that previously had no tests    ◦ Hands-on implementation of foundations, and trained teams. Swift on iOS/macOS,F#/.NET on Windows, and Kotlin on Android.• Initiated fundamental rethink of core authentication platform and drove successfulreimplementation from golang to rust, with emphasis on side-effect separation, and multi-platformsupport. Spun up and trained new team.• Established practice of applying formal methods, including TLA+, Alloy, and verifpal.• Mentored and coached engineers in functional thinking, systems design, formal methods.• Drafted and introduced Engineering North Star, Engineering Strategy, Tech Radar, RFCprocess, introducing foundational practices like feature fags, hermetic builds, property basedtesting, and various metrics and continuous improvement processes

My primary work was on the Application Architecture team helping implement Spotify's Mobile Engineering Strategy:• Researched and designed architecture patterns for the Spotify music app appropriate for hundreds of collaborating developers in a very large code base• Advocated and evangelized functional composition patterns• Coordinated and led proof-of-concept projects with stakeholders across the organization• Measured improvements in defect rates, new employee onboarding time, and developer productivity• Invested heavily in mentoring and coaching others on wide-ranging topics, including Haskell programming, software architecture, thinking functionally, and machine learningI built infrastructure to support build and test at scale:• Built custom Bazel tooling to support hermetic builds• Implemented tools to manage and reduce flakiness in test for the mobile app• Increased the throughput of our tests with mobile simulator paralellizationI worked in Spotify's ads group:• Made ads skippable on Android, iOS, and Desktop (yay!)• Leveraged Spotify's machine learning models to perform automated genre detection for arbitrary audio tracks • Built custom VAD (voice activity detection) signal processing layer to increase accuracy of existing vocal track separation models
