My profile, portfolio, and blog—in one place.
Economist by training, data scientist in practice—7+ years building pipelines, models, and BI in banking, SaaS, and AI programs. This site is my profile, a portfolio of real work, and a blog where I think out loud about data, ML, and economics.
Structure messy data into stable signals—measured, documented, ready for the next step.
Estimate scenarios with models you can inspect; probability as a tool for judgment.
Turn analytical output into views teams actually use—fewer KPIs, clearer ownership.
Name tradeoffs and constraints before choosing—technical work connected to purpose.
Production CV data pipelines—extraction, cleaning, annotation, and evaluation for image and video models.

Three ways in: who I am (profile), what I've built (portfolio), and how I think (blog).
Most projects start by stabilizing messy inputs, then estimating with models you can inspect, then shipping interfaces people run week to week. When incentives or constraints shape the answer, I make that explicit before anyone treats a chart as policy.
