Experience

1. May 2025 — Present

   AI Automation Engineer, Customer Success Operations · Ontop · Remote · US company

   Own the entire automation and AI layer for Customer Success at a global payroll fintech operating in 150+ countries.

Also built a natural-language SQL agent on Amazon Redshift and the full-stack internal CS dashboard used daily by 20+ team members.

2. Customer success platform

   Internal CS Dashboard

3. Churn detection system

4. Product analytics for customer success

   Feature Adoption System

   A system that tracks whether clients actually adopt the platform's features. Teams log what they teach clients, and the system measures whether that enablement translated into real adoption — turning training into a measurable signal.

5. Natural language to SQL
