Direction over speed.
Let compounding carry you far.
I'm WenHao Yu.
Claude Certified Architect.
Founder of Confluence Partners, helping companies adopt AI through consulting and training.
I bring AI into my work and my life to be freer, and to get closer to the life I want. I write down how it goes and what I work out along the way, for anyone willing to try it themselves.
Tools change. The way of working stays. Right now I go deepest in the Claude ecosystem.
