Message

At Seagull Software LLC, I architected an internal predictive recommendation system using Python, LangChain, N8N, and Google Gemini to alert clients to operational bottlenecks.

I lead the design of GCP ETL and data lake infrastructure processing over 10 million daily events. I also migrated legacy pipelines to GCP Dataflow, reducing execution time by 40%.

At COMPSESA S.A., I engineered Apache NiFi pipelines for high-volume sensor telemetry and designed microservices to ingest IoT data via MQTT.

Earlier, at RedFenix S.A., I developed demographic segmentation models and graph-based algorithms in Neo4J. At Datilmedia S.A., I built scalable serverless microservices using AWS Lambda, API Gateway, and AuroraDB.
