  • Databases: extensive SQL experience and core understanding of various database types and their limitations
  • Data modelling: mapping out database schema's with scalability in mind
  • CI/CD pipelines: you can set up and manage deployment pipelines (Github Actions, Azure pipelines, CircleCI or other)


  • Automated testing: test-driven development using unit and integration tests as well as end-to-end tests
  • Monitoring: error and performance monitoring with Sentry or similar services
  • Stress testing: testing APIs and end-to-end applications at scale
  • Security: you're aware of best practices to safeguard information security
  • Language: solid reading and speaking skills in English required

  • As a plus: keeping your eyes on evolutions in nocode or lowcode frameworks
