AI-Assisted Development

Using AI as a force multiplier, not a replacement.

The mobile apps here were built using GitHub Copilot, Claude, and Gemini alongside manual engineering. Architecture decisions, quality standards, and code ownership remain mine — AI accelerates execution without replacing judgment.

01GitHub Copilot — inline completions and refactors
02Claude — architecture, debugging, review
03Gemini — rapid prototyping and exploration
04Human judgment — always the final call
