4how I work
A few things I believe.
Ship with craft
Quality over quantity. If it goes out with my name on it, it gets the details right.
Stay a beginner
The moment I stop learning is the moment I stop growing. I try to say yes to hard things.
People first
Tech is a tool. People and experiences are the point. I build with empathy in mind.
Do the reps
Consistency beats intensity — in code, in training, and in life.
