• Cloud Architecture & Design
• Designed scalable and secure architecture on GCP to support the migration of legacy applications from on-premise environments.
• Conducted cost-performance trade-off analysis to select the right services (e.g., Compute Engine vs. GKE vs. App Engine).
• Designed high availability (HA) and disaster recovery (DR) strategies using multi-region deployments, managed instance groups, and load balancing.
• Cloud Migration Strategy & Execution
• Led and executed the migration strategy from on-prem/AWS to GCP for multiple products.
• Performed application discovery and dependency mapping to plan seamless lift-and-shift, or re-architecture.
• Used Compute Engine VMs for lift-and-shift workloads where modernization wasn't initially feasible.

Modernized batch and streaming pipelines using:
Cloud Dataflow for stream and batch processing (Apache Beam-based pipelines).
Pub/Sub for decoupled, scalable messaging between microservices.
Dataproc for migrating on-prem Hadoop/Spark jobs to managed GCP services.

Automation, CI/CD & DevOps

Automated infrastructure provisioning using Terraform.

Jenkins for build/test automation.

Armada for orchestrating complex delivery pipelines.

Orchestration & Workflow Management

Utilized Cloud Composer for:
* Scheduling and orchestrating ETL workflows.
* Integrating tasks across Dataflow, Dataproc, Pub/Sub, GCS, and BigQuery.
* Implementing retry logic, SLA tracking, and auditability in workflows.

Monitoring, Logging, & Reliability Engineering

Monitored services using Cloud Monitoring.

Centralized logs with Cloud Logging and created alerting policies for anomaly detection.

Cost Optimization and Governance

Monitored and optimized cloud spend using Billing Reports, Budgets etc.

Rightsized Compute Engine VMs, tuned auto-scaling parameters, and sunset unused resources.

Implemented resource labels, folders, and organization policies for effective governance.

Database Administrator

Experience in Database management for Vertica, Teradata, Replication using Orcale Golden Gate, PostgreSQL, Hadoop, BigQuery.

Experience in database installations/Upgrades and Patching.

Experience in Database migration from Oracle to Vertica/Teradata.

Database migration experience from On-Premise to AWS / GCP.

• Data warehouse management for DB2, Vertica and Hadoop.
• Data modeling using Erwin.
• Automation of database monitoring related tasks along with regular maintenance jobs using shell scripting.
• Backup and Recovery planning and implementation.
• Supporting development team with in SQL query optimization using SQL Trace, Explain Plan, SQL Query Analyzer and Optimizer Hints.
• Extensive level of Database tuning to reproduce test scenarios for QA team.
• Responsible for Report generation, monitoring disk usage, keeping systems healthy for the production environment.
• Responsible for scheduling backup scripts in cron to run on timely basis according the strategy
