Hi, I'm Sven.
I make tools that simplify my daily work. I automate annoying tasks. I write low-level code and debug it.
Windows internals, debuggers, and the tooling around AI-assisted engineering. What I learn ends up written up here and shipped on GitHub.
Tools for people who debug for a living.
Debuggers, protocol servers and native tooling. Open source where it can be, commercial where it has to be.
- open source mcp-windbg
Crash-dump analysis, driven by AI. An MCP server that lets Claude, Copilot or any MCP client drive WinDbg: dumps, live sessions and the Windows kernel.
- open source dap-dbgeng
Native Windows debugging for VS Code. A Debug Adapter Protocol server on the same engine as WinDbg: C and C++, services, and kernel-mode.
- company Liasoft
Native developer software for low-level engineers: C++ code coverage and compile-time C++ obfuscation, built and sold by my company.
