What I'm looking for

I seek a data-focused role where I can build ML solutions, optimize databases and dashboards, work in a collaborative multicultural team, and drive measurable business impact.

I am a results-driven Data Analyst and AI specialist with experience transforming complex datasets into actionable insights to support strategic decision-making. I have built Django-based web applications, designed and optimized relational databases (PostgreSQL, SQL Server, Oracle), automated ETL processes, and created interactive Power BI, Google Looker and Tableau dashboards tracking 10+ KPIs to accelerate decision speed.

I am proficient in Python (Pandas, NumPy, Scikit-learn), ML frameworks (TensorFlow, Keras), and cloud platforms (AWS/Azure), and I work effectively in fast-paced, multicultural environments.
