I execute lifecycle programs for enterprise brands, and I make them better in the process. I've spent 8 years building email and lifecycle programs for brands like Purina, Puma, IKEA, and Roku.

Before I build, I audit. If your entry logic has gaps, your segments overlap, or your data structure won't scale, I'll tell you. Then I'll fix it. Types of projects I take: • Execution + Strategy: Build lifecycle journeys and optimize the logic as I go • Audit existing automations and recommend improvements • Review segmentation strategy and suggest refinements • ESP migration planning and execution • Pure Execution (when needed): Template system development • Journey rebuilds and technical troubleshooting • Platform setup and QA Not a fit: • Full-service marketing strategy (I'm technical, not a generalist marketer) • Copywriting or design-only work Available 10-20 hours/week for the right projects.

I build and run the backend systems that keep your business scaling without breaking. Most founders don’t have a traffic problem, they actually have a systems problem.

What I handle: Sales funnels (build, optimization, troubleshooting) Email automation + segmentation Payment integrations + checkout systems Webinar + launch infrastructure Customer support systems + operations End-to-end backend optimization If your business is growing but your backend is messy, breaking, or duct-taped together, I’ll fix it and make it scalable.
