Over 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.

About PayPay Corporation — quick facts for international readers
Japan’s largest QR-code mobile-payment platform, PayPay launched in 2018 and is now used by roughly 69 million people—about one in every two smartphone users in Japan. In FY 2024 it processed ¥ 12.5 trillion (≈ US $78 bn) in GMV and commands the biggest share (≈ 64 %) of Japan’s QR / bar-code payments market. The company is backed by SoftBank and Yahoo Japan (LY Corporation).Key Accomplishments
- Mapped the entire acquisition funnel (ad → install → KYC → first purchase) in BigQuery and Looker, uncovered a critical KYC drop-off, and ran A/B tests that lifted completion rates.
- Clustered millions of users with unsupervised ML (K-means, silhouette scoring) to surface actionable segments; personalised promo flows improved early-stage retention.
- Performed sensitivity analysis on the annual marketing budget, quantified marginal ROI curves by channel, and reallocated spend to cut customer-acquisition cost while preserving LTV.
- Modelled corporate-cost elasticity versus GMV across CAPEX, cloud fees, and cashback programmes, feeding results into the FY2025 OpEx plan and sharpening margin forecasts.
- Built an executive dashboard in Looker with live funnel KPIs, cohort LTV, and cost-sensitivity sliders, giving the CEO and VPs a real-time view and eliminating manual slide prep.
- Presented a marginal-ROI channel-mix framework to the VP Marketing and CFO, guiding strategic allocation of multi-billion-yen marketing budgets.
- Developed a 12-month customer-LTV model with gradient boosting on transaction-level data, increasing forecast accuracy and establishing a data-driven break-even CAC threshold.
- Created cohort-based LTV dashboards that align acquisition spend with lifetime margin, shrinking payback periods for new users.
- Combined funnel drop-off analysis with LTV segmentation to identify a high-value yet underserved cohort and launched targeted CRM pushes that boosted mid-term ARPU.
