  • Practical experience implementing Micro-frontends or modular architectures at scale.
  • Familiarity with configuring pipelines (GitHub Actions, CircleCI) and optimizing build/test parallelization.
  • You are empathetic to the struggles of other developers and have a "service-oriented" mindset toward internal teams.
