Use AI-assisted development tools responsibly in a senior frontend workflow

Explain how you use AI coding tools such as Cursor or GitHub Copilot for implementation, refactoring, tests, and documentation while preserving code quality, security, and ownership.

Answer

Interview framing: The strongest answer is not "AI writes code for me." It is that AI accelerates work while the engineer remains accountable for design, correctness, and security.

Practical workflow:

  1. Exploration:
  • Ask AI to summarize unfamiliar files, trace data flow, or identify related tests.
  • Verify conclusions by reading the code and running the app/tests.
  1. Implementation:
  • Use AI for boilerplate, repetitive component variants, migration steps, and draft tests.
  • Keep changes small enough to review carefully.
  1. Refactoring:
  • Ask for candidate simplifications, but preserve public contracts and behavior.
  • Use tests and diffs to confirm no accidental rewrites.
  1. Testing:
  • Generate edge-case ideas and initial test cases.
  • Edit tests so they assert product behavior, not AI-generated assumptions.
  1. Security and privacy:
  • Do not paste secrets, customer data, or sensitive policy details into tools without approval.
  • Review generated code for injection, auth bypasses, overbroad permissions, and dependency risks.
  1. Team practice:
  • Document non-obvious AI-assisted changes like any other change.
  • Treat AI output as junior-draft code: useful, but always reviewed.

Good closing: "AI helps me move faster, but I still own the architecture, trade-offs, test coverage, and production risk."
