BrazilWhat I'm looking for
I am a Senior Data Engineer with a dual background in Mechatronics Engineering and Computer Science, focused on IT/OT convergence for industrial environments. I design scalable data lakes and real-time ETL pipelines to enable analytics and AI for manufacturing.
At Fundação CERTI I architected an on-premise Kubernetes-based Data Lake using MinIO and Apache Iceberg, implemented Airflow and ArgoCD for reproducible DataOps, and built high-frequency ingestion pipelines with MQTT, Spark and Kafka to support research and production analytics.
Previously, I led software and automation architecture at an additive manufacturing startup, integrating high-level Python control with PLC firmware, developing computer vision for real-time defect detection, and advancing R&D projects with industrial partners through TRL milestones.
I am completing an M.Sc. in Computer Science with focus on distributed systems and AI infrastructure for Industry 4.0, and I deploy edge Kubernetes infrastructure and RAG GenAI solutions to unlock unstructured technical documentation for engineering teams.
