What I'm looking for

I’m looking to build enterprise-grade products with strong engineering discipline—correctness, performance, and maintainability. I want to work across Angular frontend and .NET 8/microservices backend, improving reliability with solid testing and clean design.

I’m a full-stack developer with 5+ years building enterprise financial applications in Angular, .NET 8 and SQL Server. I care about correctness, performance and maintainability—the kind of problems that don’t show up until something breaks in production. I’m available from July 2026, with strong references from my current team.

In my recent role at Empyrean DC, I redesigned a SQL Server function to cut execution time from 5.3 s to 0.009 s (99.8% improvement), and refactored stored procedures that caused out-of-memory failures to improve overall throughput ~75%. I build and migrate SPAs in Angular (v11 → v19) and deliver backend microservices, REST APIs, controllers and DALs in .NET 8/C# for multi-tenant architectures, handling concurrency issues and validating behavior with xUnit/MSTest; I also designed a Cursor agentic workflow orchestrated via MCP servers to strengthen spec/PR review and test planning.
