About

Enterprise AI delivery with a product mindset.

I work at the intersection of client strategy, technical architecture, and implementation. My background spans conversational AI, speech systems, and enterprise automation, with a focus on shipping work that performs in production, not just in demos.

Designing assistants and workflow automation that improve customer outcomes.

Translating messy business requirements into implementation-ready technical plans.

Bringing together discovery, architecture, analytics, and iteration in one delivery loop.

Experience

A track record of technical delivery and measurable outcomes.

The common thread across my roles is turning conversational AI strategy into systems that teams can launch, learn from, and scale.
