Full-stack software developer skilled in .NET, React, and scalable architectures.
IsraelWhat I'm looking for
I am a full-stack software developer with 4+ years of experience building scalable, accessible web applications using .NET, React, and TypeScript. I design modular architectures and microservices, leverage SQL and Cosmos DB, and deliver clean, a11y-compliant code that improves performance and user engagement.
At Matrix I led frontend and backend development for national-level projects, improving performance by up to 40% through advanced caching, state management, and CMS integration. I built server-side architecture with ASP.NET Core and Entity Framework, integrated Dapper and stored procedures, and reduced read latency by 30% on key projects.
I also mentor and teach full-stack development, guiding hands-on learning in algorithms, data structures, and clean code principles. I move quickly between technologies, prioritize maintainability, and focus on measurable impact in production systems.
