Oliver Ernster (@oernster)

Principal Python Engineer & Software Architect: APIs, integration and platform modernisation. Author of the four-book Decision Architecture series.

➣ Explore my work: ernster.dev

My primary portfolio and entry point: the full catalogue of projects, grouped by category (Decision Architecture, applications, libraries and tooling, protocol and standards, Elite Dangerous, 3D printing and more).

Commercial licences available. Every application here is free and open source. If those terms do not suit what you are building, such as a closed-source product, a commercial licence can be bought from me separately. It covers my own code; third-party libraries keep their own licences. See commercial licensing.

  • 28+ years building software across defence, fintech, telecoms and startups
  • 13+ years Python (backend, automation, distributed systems)
  • I design systems and organisations for:
    • clear decision ownership
    • low coordination latency
    • long-term structural stability
  • Writing: CrankTheCode.com
  • Open to Staff/Principal engineering, integration/solutions architecture or modernisation-lead roles
  • Contributions to any of my repositories are under the terms in CONTRIBUTING.md
