WORK.
I lead engineering teams through complex challenges, turning ambiguity into clear decisions and dependable products. I use AI and automation to make more room for the hard thinking.
01 // How I work
Hard problems need more than good code.
I connect technical judgment with team ownership and fast feedback, especially when the path forward is not obvious.
