About
I’m AlekSandra Nastoska, a software engineer who enjoys building reliable production-grade systems and integrating complex business logic into well-tested APIs. I’ve worked across enterprise-grade C#/.NET (including .NET 8/9 and ASP.NET Core), focusing on end-to-end requirements, integration, and release quality.
Beyond traditional engineering, I also apply AI tooling and LLM APIs to accelerate development workflows, and I’m comfortable bridging deep backend implementation with practical AI adoption. I’ve contributed to automated testing and quality processes (unit, integration, BDD/Gherkin, and coverage analysis) and co-authored a peer-reviewed paper on AI trustworthiness to help teams make safer, more dependable decisions with AI in real systems.
