What I'm looking for

I am seeking roles where I can build and automate ETL/BI solutions, develop ML/NLP analytics, and turn complex data into actionable business insights within collaborative, growth-oriented teams.

I am a data engineer and analyst with consulting experience across banking, energy, and international projects, skilled in SQL, Snowflake, ODI, R, Python, Power BI, Qlik, Tableau and ETL pipeline automation. I have delivered end-to-end dashboards, automated reporting, NLP and machine learning solutions, and built robust data ingestion controls to support commercial and sustainable investment reporting.

My academic background in Business Intelligence and Analytics grounds my applied work in statistics, data mining and modeling, including gradient boosting for business valuation. I collaborate well with project teams to implement Snowflake and ODI solutions, create reproducible analytics, and translate complex operational and financial data into clear, actionable insights.
