AWS data and AI consultants for analytics and MLOps

AWS data engineers build ingestion and warehouse workloads when reporting depends on manual extracts or unreliable batch jobs.

• Redshift consulting: Design analytical schemas and loading strategies. Diagnose SQL performance using query plans and workload history, then tune table layout or workload management.
• Glue development: Implement PySpark ETL jobs and maintain Data Catalog definitions. Add schema checks and restart logic so failed loads can be investigated and rerun without duplicating records.

Machine learning engineers use Amazon SageMaker to take validated models into repeatable production workflows. They implement training pipelines and model registration, with explicit evaluation gates before a release reaches an endpoint or batch inference job.

MLOps engineers connect SageMaker Pipelines to CI/CD and configure model monitoring. They investigate differences between training and production inputs, define rollback procedures, and choose inference configurations against latency requirements and expected usage. Existing notebooks can be refactored into tested Python packages with versioned dependencies.

AWS data architects assess existing workloads before platform expansion or changes to data ownership. They document source dependencies and identify where access rules need enforcement.

• Lake and warehouse architecture: Define S3 storage layouts and Redshift boundaries around reporting needs. Plan incremental changes with explicit data reconciliation checks.
• Data governance: Configure Lake Formation permissions and IAM roles, with KMS encryption where required. Translate retention requirements into lifecycle rules and review audit logging against agreed access policies.

AWS support engineers investigate failed Glue jobs and Redshift query regressions. They trace failures through CloudWatch logs, repair affected workloads, and add alerts that distinguish delayed data from failed processing.

Cost reviews connect spending to workload behavior: unnecessary scans, oversized compute, idle endpoints and repeated processing. Specialists tune configurations against measured demand and maintain recovery runbooks. For platform changes, they validate representative datasets and compare results before replacing an existing pipeline or inference configuration.
