Re: Product Manager — AI & Developer Tools Position
Dear Hiring Manager,
I am writing to express my strong interest in the Product Manager — AI & Developer Tools position. Product Manager with 8 years shipping developer tools and B2B SaaS. Led three 0-to-1 launches, most recently an ML-powered dev-productivity feature that lifted weekly active users 34%. Comfortable across the stack: PRDs, sprint planning, prompt engineering, evals, GTM handoff. Actively seeking senior PM roles in AI product, developer platforms, or agent infrastructure at Series B+ companies.
