I’m a self-driven data engineer who loves turning complex data into reliable, scalable solutions. I excel at leading teams and delivering high-quality data pipelines, with a strong emphasis on data quality and design principles. I work well both in teams and independently and stay focused on achieving goals. Over the years I’ve built near real-time architectures on AWS using Kinesis, EMR Serverless, S3 Iceberg, and Snowflake, mentored engineers, resolved incidents, and partnered with product teams to optimize data platforms. I’m always learning and applying best practices in data engineering, cloud architectures, and lakehouse design to drive measurable business impact.
