Product Manager · Data & AI · 0→1 builder

Product manager with 12 years of experience and hands-on data practice: I define KPIs, build predictive models myself, and turn raw data into decisions. This page is where I keep the things I build. Hobby and portfolio projects, the kind that don't fit neatly on a CV.

Things I've built

Deliberately spread across conversational AI, applied data science, and interactive storytelling. The through-line isn't a single stack: it's taking each one from a blank page to something real, finished, and genuinely pleasant to use.

Conversational AI

Strohsack AI

A personality-driven AI agent that embodies a beloved plush bear, with persistent memory across sessions, LLM tool-use for durable facts, and both CLI and Streamlit interfaces.

Referral Analytics

End-to-end referral-program analysis on synthetic data: a referral-cascade graph, a two-proportion z-test, and an interpretable XGBoost model (Weight-of-Evidence + SHAP). A privacy-safe adaptation of real production work.
