What I'm looking for

I’m looking to own L3 production support and data/ETL reliability in an SLA-driven environment, partnering with engineering and stakeholders on RCA, CAPA, deployments, and secure cloud operations.

I’m an Application Support Engineer with 9+ years providing L3 / Tier 3 production and operational support for complex, high-availability enterprise and data-driven systems. I own the full incident lifecycle—monitoring, triage, and resolution of critical (P1/P2) incidents—within strict SLAs.

I’m known for root cause analysis (RCA) on complex data discrepancies and job failures, followed by corrective and preventive actions (CAPA) to prevent recurrence. I coordinate Incident, Problem, and Change Management through CAB processes and drive resolution alongside developers, vendors, and business stakeholders in 24x7 operations.

On the engineering side, I bring strong SQL scripting and query optimization across SQL Server, Oracle, and PostgreSQL, supporting data warehouse/BI workflows and scheduled jobs (SSIS, SSRS, SSAS, SQL Agent). I also support ETL and batch-job monitoring, reconciling data issues and restoring failed workflows to protect data integrity.

I leverage AWS cloud operations (Lambda, S3, RDS, CloudWatch) and .NET expertise (C# / .NET Core, ASP.NET MVC and Web Forms) to troubleshoot application and integration issues. I’ve also led an on-premises-to-AWS migration with seamless cutover, remediate application security vulnerabilities, and use GitHub Copilot to accelerate fixes while maintaining quality through review and testing.
