What I'm looking for

I'm looking to build maintainable, high-performance backend systems with .NET, ASP.NET Core, PostgreSQL, Clean Architecture, automated testing, and CI while growing through practical engineering challenges.

I built a high-throughput structured-log ingestion and query service using .NET 10, ASP.NET Core, PostgreSQL 17, and Docker. Using bounded producer-consumer processing, PostgreSQL binary COPY, and atomic minute rollups, I achieved approximately 14,999 logs per second and approximately 2 ms aggregation p95 within 0.5 CPU and 256 MB application limits.

I've also built a perfume store management system for inventory, invoices, customer debts, financial transactions, and reporting. I focus on maintainable .NET systems using Clean Architecture, REST APIs, SQL databases, automated testing, CI, concurrency, and performance optimization.
