About

I am a Data Engineer who loves solving expensive problems. Currently, I specialize in building high-availability ETL pipelines and optimizing cloud data warehouses at CSG. My focus isn't just on moving data, but on moving it efficiently and cost-effectively. What I do: 🚀 Cloud Architecture: Recently led a migration to Redshift Serverless that improved query performance by 30%. ❄️ Data Warehousing: Experienced in designing scalable schemas and pipelines for Snowflake and Redshift. 💰 FinOps: Built a custom auto-scaling engine (using AWS Lambda & EventBridge) that dynamically adjusts compute based on business hours, significantly reducing cloud bills. 🤖 Automation: I hate manual toil. I'm currently architecting GenAI Agents (using AWS Bedrock) to automate data remediation workflows. Beyond the 9-to-5: I enjoy coding my own projects. My latest is Audio Weaver (https://audioweaver.online), a browser audio editor. Running a live site with real users helps me understand the "full stack" better, which helps when designing data pipelines. Tech Stack: Python, SQL, AWS (Redshift, Glue, Lambda), PySpark, Snowflake, Airflow. Open to connecting with folks in the Data & AI space!
