What I'm looking for

I’m looking for a data engineering role where I can build real-time pipelines and cloud data lakes/warehouses, strengthen data quality and governance, and partner with stakeholders on analytics that drive business outcomes.

I’m a results-driven Data Engineer with 7+ years of experience designing and implementing scalable data solutions across Azure, AWS, and big data ecosystems. I focus on real-time data pipelines, ETL/ELT development, cloud architectures, and analytics platforms, delivering business-critical insights with strong attention to data quality and performance.

In my most recent role, I built streaming and ingestion capabilities for telecom taxation and CDR processing using Kafka, NiFi, Spark, and Airflow, including a data lake architecture with Hudi and MinIO. I’ve also developed AWS and Azure data lake/warehouse solutions, implemented governance and security best practices (including RBAC and compliance), and supported analytics through platforms like Apache Druid, Superset, and Power BI—while mentoring engineers and strengthening code quality through reviews.
