About Shota
Transformation Strategist | Specialist in Data-Driven Growth, End-to-End Operating Models & Advanced Analytics
Summary:
I help company leaders turn messy data into clear growth wins and bottom-line impact.
With a foot in both brick-and-mortar operations and high-velocity payments, I bring the rare mix of board-level strategy and hands-on analytics needed to scale revenue while safeguarding margin.
Why work with me
- ROI-first mindset: Every roadmap, experiment, or dashboard I deliver is ranked by payback period and value—so you know exactly where to invest first.
- Full-funnel visibility: I trace the entire customer journey—from ad click and KYC to repeat purchase—and surface the precise levers that move conversion, retention, and LTV.
