The interface is the easy part. I design what holds it together.

From AI interaction models and pricing systems to platform architecture, I build the invisible foundations that help products scale—and businesses grow.

The Blend

Four blends of practice.

Each project, a different blend of constraints, craft, and consequence. The first two open onto full case studies.

01
Vera Fill My Books
Replaced the company's flat subscriptions business model with AI-powered performance pricing: creating a scalable growth engine projected to drive $6M in annual revenue for the company.

Within two weeks of launch, the platform generated 37% more revenue than the previous product's flat monthly subscription, drove $1.19M in GMV, and retained 78% of migrated businesses.

02
Vera AI Platform
Designed the foundational AI platform that unified Vagaro's next generation of AI agents, creating reusable conversation patterns, interaction models, and workflows across support, reporting, business creation experiences, and future AI capabilities now built upon.

Reduced support workload by increasing AI support deflection from 60% to 90%, while establishing reusable patterns for future AI products.

03
Connect Messaging Platform
Discovered a revenue leak hidden inside customer conversations and transformed messaging into a revenue-generating communication platform.

Designed it as a conversion engine that increased appointment conversions by 54% for businesses, with 25% MoM user growth.
