Artur User

I’m an early-career data professional with strong foundations in statistics and hands-on experience turning complex data into practical, actionable solutions. I’m autonomous, self-taught, curious, and fast-learning, and I focus on building decision-oriented analytical systems.

I work across financial, operational, and commercial domains. In my projects, I’ve led qualification and automation logic for lead triage and commercial prioritization, built SQL/Python pipelines for credit risk analysis, and created operational delay analysis and prediction with temporal, route, and seasonality features—also validating timestamp inconsistencies and source data quality issues.

I also apply machine learning techniques to support investment decisions, including HMMs for regime detection and time-series analysis, plus interpretable modeling and Power BI dashboards with KPIs. Right now, I’m doing freelance investment analysis and portfolio monitoring—tracking risk/return and adjusting recommendations as market conditions change.
