Czechia
Summary
👤
Senior🎓
Top SchoolRené Stein is a senior software architect and long-time freelancer based in Czechia with deep expertise in systems-level and application development across C#, C++, Rust and x86/x64 assembly. He brings decades of hands-on experience in .NET (including .NET 5+ and .NET Framework), network programming (including a TLS 1.3 implementation), reverse engineering with Ghidra, and Win32/Windows internals. René has designed real-time and embedded systems, mobile and embedded Linux solutions, and complex server-side architectures using ASP.NET, WPF, Entity Framework and MSSQL. A former C# MVP, he blends pragmatic engineering with formal system design, UML and business analysis to turn ambiguous requirements into robust, maintainable solutions. His background spans roles from analyst and developer to technical director, reflecting both executional depth and strategic perspective. Unusually for an architect, he still codes low-level assembly and reverse-engineers systems, keeping his understanding of platform internals sharp.
