about
Hi, I'm kopticx — a full-stack engineer who leans backend. I design and build scalable, high-performance services with .NET, Go, and AWS, applying Clean Architecture, Domain-Driven Design, and microservices to keep enterprise systems maintainable as they grow.
Most of my time goes to optimizing cloud infrastructure, cutting execution times, and integrating complex third-party platforms — making systems faster and more reliable along the way.
