AI-Driven Technical Leader

Daniel
Yu

Hands-on technologist who still writes code every day. 20+ years building systems, leading teams, and shipping products. Now achieving 10x productivity through AI-assisted development with Claude Code and Co-Pilot. I bridge the gap between deep technical execution and team leadership—equally comfortable architecting cloud infrastructure, pair-programming with AI, or mentoring the next generation of developers.
