Case Studies & Engagement Areas

A major federal modernization program required migration and modernization of hundreds of Oracle, SQL Server, PostgreSQL, MySQL, and MongoDB databases to a multi-cloud environment spanning AWS GovCloud, Azure Government, OCI, and GCP — within strict FedRAMP compliance boundaries, near-zero downtime requirements, and tight fiscal year delivery windows.

Led database engineering workstream — assessment of existing databases, architecture design for target cloud environments, Terraform and Ansible IaC standards for automated provisioning, right-sizing analysis, and phased migration execution with validation gates at each stage.

U.S. Navy Military Sealift Command required database replication architecture capable of maintaining data integrity on ship-based systems operating under intermittent and denied satellite connectivity. Fully managed cloud databases cannot run in the disconnected afloat environment. Legacy SAP MobiLink architecture needed modernization to a more scalable, maintainable event-driven system.

Designed hybrid EC2-native MariaDB architecture for afloat (ship) environments syncing with RDS-based databases ashore. Leading architectural transition from SAP MobiLink to Apache Kafka event-driven replication — a durable pub/sub queue-and-replay system that guarantees data integrity across network disruptions of any duration.

Healthcare and eCommerce organization experiencing recurring unplanned downtime, performance bottlenecks affecting customer-facing systems, and SOX audit readiness gaps across SQL Server, PostgreSQL, MySQL, and cloud-hosted database environments supporting 1,000+ business users.

Implemented proactive monitoring architecture using CloudWatch, Splunk, Tanium, and New Relic. Performed deep-dive performance analysis on critical query workloads. Redesigned indexing strategy on high-traffic tables. Automated recurring DBA operational tasks through PowerShell and SQL Agent scripting.

Organization required reliable ETL pipeline architecture processing 5TB+ datasets daily across heterogeneous systems including Oracle ERP, SQL Server, MySQL (Hybris), and Amazon Redshift — supporting BI analytics for over 1,000 business users with strict latency and data quality requirements.

Designed and implemented end-to-end ETL pipeline architecture using SSIS, Qlik Replicate, and Informatica IICS. Integrated data across Oracle ERP, SQL Server, MySQL, and cloud databases. Supported Redshift and Tableau BI environments with alerting, SLA monitoring, and automated error recovery.

Major enterprise telecom provider needed high availability and disaster recovery architecture across SQL Server, Oracle, and MySQL/MariaDB environments supporting commercial and government workloads — while reducing the significant manual effort consumed by daily DBA operations.

Implemented Always On Availability Groups, clustering, and log shipping HA/DR architecture. Conducted deep performance analysis identifying CPU, disk I/O, and memory bottlenecks. Built comprehensive PowerShell and SQL Agent automation library covering monitoring, maintenance, alerting, and routine operations. Integrated AWS RDS and Aurora for cloud database layer.

Healthcare organization required reliable, fully-documented database administration for clinical and operational systems across SQL Server 2005–2016 environments — with comprehensive disaster recovery strategy, performance optimization, and SSIS-based ETL pipelines supporting clinical reporting workflows.

Full lifecycle DBA ownership across production, test, and development environments. Designed and implemented DR strategy including full, differential, and transaction log backup chains with regularly tested recovery procedures. Built SSIS packages for clinical ETL. Performance tuning using SQL Profiler and Query Analyzer on clinical system workloads.
