Expert, AI Engineer

• Lead the team to improve scalability, reliability, and cost-efficiency of the Data Platform.
• Design, build, and deploy data pipelines (batch & streaming) using Spark orchestrated via Airflow.
• Develop libraries and frameworks for data ingestion, transformation, and governance with clean architecture principles.
• Collaborate with Data Architects to design/review data models, enforce data contracts, and maintain schema governance.
• Optimize performance with partitioning, caching, Z-Ordering, and metadata management in lakehouse environments (Delta/Iceberg/Hudi).
• Ensure security and compliance: IAM, encryption, secrets management, and GDPR/CCPA adherence.
• Drive CI/CD for data workflows, IaC (Terraform), and container orchestration (Kubernetes).
• Monitor SLOs/SLAs, implement alerting, and lead incident responses and postmortems.
• Design and operate end-to-end ML/LLM pipelines: data prep, training, evaluation, and deployment.
• Build RAG architectures, vector search, and embedding pipelines for LLM-based applications.
