Data Engineer at MORSCO — Reece USA building resilient API-to-Snowflake ingestion pipelines; architecting Janus IA off-hours.

Message

At MORSCO — Reece USA, I own the lifecycle of ingestion pipelines into the corporate Snowflake warehouse, from source contracts and Talend authoring to validation and production handoff. I also engineered a resilient API-to-Snowflake pattern used across multiple integrations.

At Ernst & Young, I co-led Exxon Mobil's SAP-to-Snowflake migration, reconciling emissions metrics with complex SQL and building Python tools to validate batch data. At Oracle, I built machine-learning models to predict client churn and renewal risk, and designed an NLP sentiment-analysis layer for support tickets and client notes.

Through Outlier AI · LATAM Coders, I develop and evaluate AI models for clients including Tesla and OpenAI. Off-hours, I architect Janus IA, a personal multi-agent operating system using MCP-orchestrated LLM agents, a three-layer brain, and a React dashboard.
