Jameson Sansone

Marketing Operations & GTM Systems Lead

Building the infrastructure that turns marketing activity into measurable revenue.

I’m a technical MOps leader bridging the gap between GTM strategy and execution. With a background in growth, I view the revenue engine through a full-funnel lens—instrumenting tech stacks to automate manual work and enhance data visibility across HubSpot, Salesforce, and other MarTech platforms. I build the scalable infrastructure that connects teams and ensures data maps accurately from lead to revenue.

Projects

Captain Jim: An Interactive WWII Memoir with RAG

I built a full-stack RAG application to transform my grandfather's 200-page WWII memoir into an interactive conversational experience for his 103rd birthday.

  • RAG Engine: LlamaIndex and FastEmbed for local retrieval; GPT-4o for summarizing our response.

  • Custom Voice: ElevenLabs voice cloning of my grandpa's voice for immersive book excerpt readings.

  • Architecture: Decoupled FastAPI backend on Render with a responsive Vercel frontend.

Stack: Python | LlamaIndex | GPT-4o | ElevenLabs | Vercel | Render

Substack: The Signal & The Stack

The Signal & The Stack is my lab for sharing technical blueprints, AI-driven builds, and the logic behind engineering a 2026 revenue engine.
