Abstract
I work as a Principal AI Product Manager at Make, operating in a Founder in Residence role. I work deeply with design, engineering, product, and technical staff to turn new ideas into prototypes, products, and new market opportunities.
Seb Builds is where I share projects, build logs, agent workflows, and lessons from shipping in public.
