Project - Teradata Exit

Key Responsibilities

- Implement tailored migration strategies, including:

- Lift-and-Shift: Replicate schemas and processes in Azure.

- Re-Architect: Optimize workflows for cloud-native architectures.

- Hybrid Migration: Gradually transition workloads with on-premise retention where needed.

- Migrate schemas using Azure Database Migration Service or custom scripts and manage data transfers via Azure Data Factory.

- Conduct rigorous testing to validate data integrity, completeness, and performance by comparing Teradata and Azure results.

- Refactor application queries to support Azure SQL or Synapse-compatible SQL.

- Rebuild and optimize ETL/ELT pipelines using Azure Data Factory, integrating with Azure Databricks for big data processing.

Project - Synapse Exit

Key Responsibilities:

- Migrate from Synapse to Azure DataCore using lift-and-shift, re-architecting, or hybrid strategies.

- Ensure schema compatibility and manage data transfers with Azure tools.

- Validate data accuracy and refactor queries and ETL pipelines for Azure DataCore.

Project - Datacore PaaS Upliftment

Key Responsibilities:

- Design and optimize end-to-end ETL workflows using Azure Data Factory and PySpark, ensuring efficient, secure, and compliant data processing at all stages.

- Build, manage, and enhance ADF pipelines with precise scheduling and integration into Azure DevOps for robust version control.

- Deploy and maintain Synapse SQL resources for stable and scalable production environments.

- Manage data migration activities from Cloudera Kudu to Azure Data Storage, ensuring data integrity and seamless transition.

- Administer PostgreSQL tables to support structured data storage and efficient querying.

- Design and implement secure, compliant frameworks for effective data governance and risk mitigation.

- Improved query performance by around 20% for migrated tables, compared to the previous infrastructure.
- Ensured 99.9% uptime for uplifted tables throughout the migration process in Production.
- Reduced infrastructure costs by approximately 10% after migrating 400 tables to the Datacore PaaS framework.
