How I work with teams

I work with both hiring managers and clients. Below is how I typically engage as a Product & ML Data Scientist focused on e-commerce, experimentation and AI.

For hiring managers (full-time / contract)

I'm interested in roles where I can own the analytics, experimentation and ML layer of the product, especially in e-commerce, marketplaces and consumer apps.

Product & ML data science across experimentation, user behavior and pricing.
A/B test design, guardrails and analysis for product features and growth experiments.
Customer, funnel and cohort analysis to find where revenue and retention leak.
Partnering with PMs, engineers and designers to turn insights into shipped changes.

Ideal titles: Product Data Scientist, ML Data Scientist, Senior / Lead Data Analyst (product-focused).

For clients & founders (consulting)

If you're running an e-commerce or consumer brand, I can help on a focused project basis.

Experiment Audit

Review one existing or planned experiment, check the metrics, guardrails and sample size, and provide a clear recommendation.

E-commerce Analytics Starter Kit

Set up core tracking, key dashboards and recurring reports so you understand acquisition, conversion, retention and unit economics.

AI / ML Prototype Sprint

Build a small but concrete prototype — for example review analytics, basic recommender, or pricing intelligence — that your team can explore and iterate on.
