What I'm looking for

I seek data engineering roles building scalable streaming and batch ETL systems, using modern data platforms, collaborative teams, and opportunities to architect large-scale data solutions.

I am a data engineer focused on building scalable, reliable streaming and batch ETL pipelines using Kafka, Spark, Delta Lake, and Kubernetes. I design data models and medallion architectures to support petabyte-scale ingestion, transformation, and recovery.

My work includes migrating systems to new vendors, restructuring data models, and deploying services in Kubernetes for reliability and scalability. I have implemented end-to-end projects that leverage Kafka, Redis, cloud workers, and materialized services to deliver real-time functionality and analytics.

I have experience designing ETL frameworks that integrate web APIs, SQL servers, and static sources into Postgres and Oracle data warehouses, and I automate workflows with Apache Airflow and CI/CD tooling. I also build business-facing dashboards and manage access with Power BI.

I bring strong system administration experience across Linux and Windows servers, practical skills with AWS services (EMR, S3, IAM, Glue, Athena, Redshift, Lambda), and a collaborative mindset focused on delivering data-driven solutions for stakeholders.
