AI & Modern Development

  • Practical experience using Claude for programming efficiency and tools such as GitHub, Copilot, Cursor, or similar
  • Understanding of where AI adds value in the software development lifecycle
  • Interest in emerging areas such as LLM APIs, RAG, or automation is beneficial but not essential

If you’re a developer who enjoys working across the full stack, solving challenging problems, and using AI to improve how software is built, we’d love to hear from you.
