I’m a Full Stack .NET developer with 5+ years building enterprise B2B SaaS applications using C#, ASP.NET Core Web API, Angular, and SQL Server. I delivered an end-to-end Procure-to-Pay platform (PRM360) across vendor management, purchase orders, GRN processing, invoice matching, and spend analytics.

I focus on performance, reliability, and clean engineering. I improved API response times by 30–40% through SQL composite indexing and query optimization, and I resolved production-critical concurrency issues in real-time bidding workflows using optimistic concurrency control.

In production, I own the full troubleshooting path—diagnosing issues via root cause analysis, deploying fixes with minimal downtime, and maintaining clear incident documentation. I also collaborate in Agile/Scrum through sprint planning, code reviews, and unit-based test automation to keep code quality consistently high.

During a career break, I independently designed and built an AI-powered Travel Planner using Azure OpenAI and Clean Architecture. I implemented Azure OpenAI (GPT-4o-mini) integration with CQRS (via MediatR), JWT authentication with refresh token rotation, and a SQL Server + Entity Framework Core data layer—demonstrating hands-on, modern .NET, Angular, and AI-adjacent application patterns.
