Hi, I'm Zach

Zachary Bullard

Product Manager II, AI & Content at BOLD

Product manager building AI-powered platforms that scale globally.

I own a $10M+ AI content platform at BOLD serving 35-40 resume/cover letter portals across 15+ languages. I design prompt architectures, lead multi-LLM evaluation, and drive product strategy from vision to execution. My work combines deep technical knowledge (API design, prompt engineering, evaluation frameworks) with business impact (2.5x revenue growth, >3% conversion lift, 40% defect reduction).

Previously led data education programs at TripleTen (Yandex), and spent 10 years teaching English in Russia—experience that informs my user-centered approach to complex product problems. I build systems where none exist, lead through influence, and deliver measurable results in ambiguous environments.
