What I'm looking for

I seek roles building scalable data architectures and ML solutions in collaborative teams, with opportunities for global impact and technical leadership.

I am a results-driven Data Engineer and Data Scientist with extensive experience building scalable data pipelines, real-time processing systems, and predictive analytics for financial and enterprise systems. I have delivered migrations, optimized ETL workflows, and implemented AI-driven solutions that improved reporting accuracy and reduced processing time.

My work spans cloud platforms (AWS, GCP, Snowflake), big data tools (Spark, Hadoop, Kafka, NiFi, Airflow), and multiple database systems, supporting millions of users and mission-critical financial operations. I am open to relocation and global opportunities and focus on creating reliable, performant data architectures that enable better decision-making.
