Cloud Data Warehousing & Snowflake
Expertise in Snowflake including Stored Procedures, Streams and Tasks, Snowpipe, Time Travel, Zero-Copy Cloning, and Stages. Design and optimization of Snowflake Views and Medallion architectures using dbt for automated data quality testing.
ETL & Integration with Informatica IICS
Extensive experience with Informatica Intelligent Cloud Services (IICS) including CDI, CAI, and Taskflows, as well as Informatica PowerCenter. Migration of legacy workflows to IICS and design of hybrid ETL/API pipelines for enterprise data integration.
AWS Ecosystem & Cloud Data Engineering
Hands-on experience with AWS services including S3, Glue, Athena, Kinesis Firehose, EC2, CloudWatch, and IAM. Management of serverless ETL pipelines, data lake provisioning with Terraform, and CI/CD pipeline setup using GitHub Actions.
Advanced SQL & Python Scripting
Proficiency in Advanced SQL including Window Functions, CTEs, and PL/SQL, as well as Python for scripting, data parsing, and automation. Refactoring of complex Oracle PL/SQL procedures and development of end-to-end data transformation logic.
Apache Airflow & Workflow Orchestration
Orchestration of automated Apache Airflow workflows for extracting JSON payloads from external APIs, implementing idempotency and backfill capabilities in production-grade data pipeline architectures.
Data Security & Compliance
Implementation of secure data exchange pipelines applying PGP encryption for third-party delivery. Execution of CCPA privacy workflows for sensitive user data deletion requests to ensure regulatory compliance.
DevOps & Tooling
Practical use of Git for version control, Jira and ServiceNow/HappyFox for project and incident management, PagerDuty for Severity-1 incident response, and Postman for API testing.
Talend & ETL Development
Design, building, and testing of end-to-end Talend integration jobs following the full Software Development Life Cycle (SDLC), progressing from support operations to active ETL development.
Infrastructure as Code & Terraform
Provisioning of AWS S3 Data Lakes and keyless IAM security roles using Terraform to enforce configuration consistency and implement Infrastructure as Code practices.
