David Vance

Developer Terminal

Systems & infrastructure engineer based in London, UK.
Focusing on Linux runtimes, CI/CD pipeline automation, containerization, and reproducible build systems.

🔧 Core Areas

Area Tools & Technologies
CI / CD Automation GitHub Actions workflows, reusable actions, matrix runners
Container Runtimes Docker, OCI containers, multi-stage builds, minimal base images
Packaging & Tooling Python packaging, wheel building, virtual environment isolation

🛡️ Infrastructure Principles

  1. Hermetic & Reproducible: Pinning dependencies and base layers for deterministic environments.
  2. Fast Feedback Loops: Caching test fixtures and pre-compiling native extensions to reduce CI runtime.
  3. Automated Hygiene: Linters, type-checkers, and security scanners running as non-negotiable gates.
