What I'm looking for

I am looking for a role that allows me to leverage my data analysis skills in a collaborative environment, where I can contribute to innovative data solutions and grow professionally.

I am a dedicated Business Intelligence Engineer with a strong passion for data analysis and a commitment to helping organizations understand their customers better. My experience includes developing and implementing interactive Power BI dashboards and leveraging machine learning techniques to extract valuable insights from data. I thrive on transforming complex data into actionable strategies that drive business growth.

Throughout my professional journey, I have honed my skills in data processing, integration, and visualization. At BIAT, I successfully managed data with SQL and DBeaver, automated ETL processes using Talend, and created dynamic dashboards that enhanced decision-making. My academic background in computer science, coupled with my specialization in ERP/BI, has equipped me with the technical expertise to tackle challenging data-related projects effectively.
