Analytics • Business Intelligence • Decision Intelligence

Python • SQL • Power BI • Simulation • Optimization • Reproducible Analytics

I build analytics and decision-support systems that transform operational, commercial, marketplace, and supply-chain data into KPIs, dashboards, simulations, risk assessments, and actionable business recommendations.

My portfolio connects Business Analytics, Operations and Decision Intelligence, and Analytics and Research Engineering through reproducible projects grounded in real-world data, quantitative methods, and executive communication.


Professional Focus

Business Analytics & BI

KPI development, executive reporting, dashboard design, revenue analytics, marketplace intelligence, operational risk, cost analysis, and business insight generation.

Operations & Decision Intelligence

Supply-chain analytics, simulation, optimization, scenario analysis, policy benchmarking, resilience evaluation, and data-driven decision support.

Analytics & Research Engineering

Reproducible Python pipelines, automated validation, testing, GitHub Actions, Numba acceleration, evidence provenance, and research workflow automation.
