Turning raw data into dashboards, pipelines into insights, and complexity into clarity
💡 I build end-to-end data pipelines and MLOps systems — from raw ingestion to production-ready dashboards — with a focus on Docker, CI/CD automation, DuckDB, and data storytelling that drives real business decisions.
🛠️ Core Stack
SQL • Python • PostgreSQL • DuckDB • Docker • GitHub Actions • MLflow • Tableau • Power BI• Excel
📊 Focus Data Engineering • MLOps Automation • Business Intelligence • ETL/ELT Pipelines • Analytics Engineering
⚡ How it works (architecture deep-dive 🔬 for engineers)
This profile is a self-updating MLOps demo — a living portfolio showcasing production-grade automation.
