Key Project Objectives include:

  • Cloud Foundation & Landing Zone: Deploy target hybrid network architectures, establishing a secure Landing Zone and hybrid Data/AI platforms on AWS.
  • Security, Compliance & Governance: Operationalize on-prem tokenization (achieving zero raw PII in the cloud), resolve policy blockers to include AWS in the ISMS, and establish a Cloud Center of Excellence (CCoE) to govern Cloud adoption.
  • AI Chatbot & Voicebot Design & Implementation: Develop and operationalize a flagship Customer Care Chatbot and Voicebot as the first hybrid-setup consumer.

 

Key Responsibilities:

  • Design, implement, and maintain the AWS Data Platform foundation, including Amazon S3 lake layout, Apache Iceberg table format standardization, and AWS Glue Data Catalog integration.
  • Build and optimize scalable batch and streaming data pipelines using Amazon EMR (Serverless and EMR-on-EKS), Apache Spark/PySpark, Apache Flink, and Amazon Athena with workgroup cost caps.
  • Implement data tokenization and de-identification pipelines on the data side (PA-T) using Protegrity/Spark UDFs for batch, Spark Streaming for micro-batch, and Kafka Connect SMT for streaming PII masking prior to cloud transit.
  • Build and manage real-time streaming architectures with Amazon MSK (Managed Streaming for Apache Kafka), MSK Replicator/MirrorMaker2, and Schema Registry integration.
  • Implement Medallion Architecture (Bronze, Silver, Gold layers) for lakehouse data modeling, automating Iceberg table registration and backfill frameworks.
  • Execute data migration waves across non-PII and PII datasets using AWS DataSync, automated register steps, and streaming migration configs.
  • Configure data access control and governance models using AWS Lake Formation, cross-engine authorization, AWS Macie for PII detection, and Informatica Data Catalog (Axon, EDC, BDQ) integration.
  • Build automated schema-drift identification components, GitLab CI/CD pipeline integration for dataset synchronization, and automated data contracts/circuit breakers.
  • Implement DataOps observability, centralizing logging via Amazon CloudWatch, configuring FinOps cost & anomaly monitoring, and setting up automated alerts.
  • Author technical documentation, operational runbooks, disaster recovery (DR) procedures, and cutover/rollback playbooks for data platform hardening.
