What I'm looking for

I’m looking for a team where I can design data platforms for AI-ready products—owning architecture, orchestration, governance, and CI/CD—while delivering measurable improvements in reliability, time-to-insight, and platform autonomy.

I’m an experienced Data Engineer with 5+ years specializing in batch, streaming, and data platform solutions on AWS. I’ve led end-to-end development of an AI-ready data platform from scratch, enabling scalable data and AI product delivery through Snowflake-based architectures, modern orchestration, and infrastructure-as-code.

In my current role, I built a unified, organization-wide data backbone using Airflow, dbt, Snowflake, and AWS EKS, including a greenfield ingestion framework that automated 100% of delivery. I also architected real-time Kafka + CDC synchronization into Snowflake Dynamic Tables, deployed a governed semantic layer (Cube.dev), and operationalized an LLM-driven sentiment analysis pipeline, while previously driving lakehouse modernization, governance adoption, and ~$200,000 in annual savings.
