01 — The long way here
Who she is, and how she got here.
Senior Staff Data Scientist at Intuit — new role, May 2026.
- 01Where it started
A town of 2,000 people in central Poland. A thirty-minute drive each way, every day, for English lessons. One scholarship awarded nationwide to Headington — a boarding school just outside London. She was the student picked.
- 02UCL · the physics years
An MSci in Atomic & Particle Physics and Physical Chemistry at University College London, with a thesis in nanotechnology. The training to model a system before trusting it, and to hold uncertainty without flinching — the same instincts she now brings to every experiment and dashboard.
- 03The detours that weren't detours
A year volunteering at a business incubator in Kenya. Two winters absorbing the language and culture in Beijing. A season living on a boat in the Red Sea as a PADI Rescue Diver. Thirty-plus countries on the count. Four languages in active use.
- 04Into data
YouNoodle and FiveStars — where she learned to make small data tell honest stories. Medium — where she ran experimentation for web and mobile and built the Redshift pipelines underneath. Square / Block — from Senior IC to Manager to Identities Data Science Tech Lead: rebuilt sales forecasting, uncovered $0.5M / year in fee exposure, authored the org-wide ETL template, sat on the AI Steering Committee, and became the heaviest internal user of GooseAI, Block's in-house LLM platform.
- 05Now
Sr Staff Data Scientist at Intuit since May 2026 — the next hard thing. A serious enough baker to belong on Bake Off. Loves cats. Don't call her Kat.
Where she works
Where the work lands.
- Identity verification — risk, fraud, and the merchant identity graph at Fortune-500 scale.
- Sales analytics — forecasting, reporting overhauls, and the org rituals that make numbers trustworthy.
- E-commerce & product — onboarding funnels, editor experiences, growth experimentation.
- Data infrastructure — ETL templates, data contracts, observability tooling (Anomalo, Select Star, Growthbook).
- LLM operations — Snowflake Cortex with Claude / GPT, GooseAI for support analysis, evaluation discipline at scale.
How she works
Executive presence. IC depth.
- Physics-trained rigor — holds uncertainty without flinching and models the system before trusting it.
- Mentor and people manager — coached four FTEs and one intern; directly contributed to two promotions.
- Org-wide experimentation leader — led the Optimizely rollout for e-commerce and co-hosted company-wide A/B testing office hours.
- Served on the AI Steering Committee, helping shape enterprise AI strategy from the inside.
- Co-led the virtual Data Town Square — a recurring 200+ attendee practitioner forum.
Beyond the desk
Off-duty
Calm under pressure. Literally.
PADI Rescue Diver. The training to brief, to checklist, and to stay measured when the room gets loud — which turns out to be exactly the training a Sev-1 needs.
Quiet hours
Reader, thinker, traveler.
Long-form reading, slow Sundays, an unhurried glass of something good. The space where the best ideas actually arrive.
