• Can jump into an existing React, Vue, or Svelte frontend and ship changes, with or without a coding agent.
• Have deployed containerized apps to a cloud provider and have a working understanding of IAM, scaling, logging, and observability.
• Have worked directly with clients or product stakeholders and can explain technical work in language anyone can understand.
• Excited about what's happening in the AI space but stay focused on delivering value.
