What I'm looking for

I’m looking for a role where I can own backend reliability—driving incident resolution, root-cause analysis, and API/database optimization—while building stable enterprise solutions in .NET and Oracle on modern cloud platforms.

I’m a Senior Software Engineer with 15+ years of experience building, supporting, and maintaining enterprise applications, databases, APIs, and cloud-based solutions. I bring a strong background in .NET and Oracle PL/SQL, with deep expertise in SQL Server and production incident response.

In my current role, I investigate and resolve production incidents using ServiceNow, then perform root cause analysis across application and data layers. I analyze Oracle PL/SQL code and business logic, troubleshoot API integrations, and validate requests/responses using AWS logs, while coordinating fixes with front-end teams.

Previously, I developed and optimized SQL Server solutions, created complex queries, and designed SSIS integration packages to support reporting and data integration. I’ve also contributed to process improvement using AI-assisted analysis tools and delivered customer-facing platforms with modern web stacks.

From BI and data warehouse architecture to mission-critical application support, I’m comfortable bridging legacy systems and modern cloud platforms. My focus stays on stable delivery, database optimization, and clear cross-functional collaboration.
