Work Experience

Co-founded (2025 - present)

  • A B2B2C private-jet charter marketplace — charter companies publish empty-leg flights, customers search, compare and book.
  • The candidate co-founded and built the product end to end, with a Python and FastAPI backend with async endpoints.
  • Worked on PostgreSQL schema design and geospatial search, with a TypeScript frontend.
  • The app is essentially complete; launch is gated on the business and regulatory side of charter operations.

Contract Software Engineer (2024 - present)

  • The candidate architects the platform behind the national e-government platform and the state's citizen app on Android and iOS.
  • Built a cloud-native foundation with multi-cluster OpenShift provisioned as code across Oracle Private Cloud Appliances and bare-metal.
  • Implemented GitOps-driven delivery via self-managing ArgoCD, with end-to-end observability, secrets, identity and policy on sovereign infrastructure.
  • Worked with Python and Java services, REST API design, PostgreSQL and Oracle data layers, and Kafka messaging for real-time event flows.
  • Owns OAuth 2.0 and OpenID Connect through Keycloak, secrets in Vault, and CI/CD pipelines including GitLab CI, Argo CD, container builds and automated testing and scanning.

Contract Software Engineer (2017 - 2023)

  • The candidate helped lead development of a help-desk SaaS used by tens of thousands of companies.
  • Contributed across feature work, architecture and the DevOps underneath it.
  • Built the Android app in Kotlin, including feature work through to signed release builds on the Play Store.
  • Worked on the PHP, Java and Python backend and the JavaScript frontend, including REST APIs between the backend and mobile and web clients.
  • Ran the AWS infrastructure with Terraform, including Kubernetes on EKS under Argo CD.
  • Part of the leadership team for two years, mentoring developers and running hiring.

Co-founded (2024 - 2024)

  • A spatial Formula 1 companion app, native in Swift for visionOS.
  • The candidate owned all real-time telemetry — loading, handling and playback driving the spatial visualisation.
  • Led a small cross-functional team (engineering, 3D, UI/UX) from concept to a shipped product, on a live-sports data source the candidate didn't control.
  • Featured by Forbes as “the best reason yet to buy a Vision Pro.”
  • Sunset after an F1 cease-and-desist and Apple discontinuing the Vision Pro.
