Rockstar🎓
Top SchoolWaqar Ahmed is a Senior Software Engineer with 11 years of experience specializing in C++ and Qt, known for shipping performance-focused desktop applications and tooling. Based in Islamabad, he leads development at KDAB, where he’s driven delivery of a data-intensive medical control application and ported the GammaRay Qt debugger from Qt5 to Qt6 while improving its robustness. An active KDE contributor and maintainer of QOwnNotes, he frequently tackles large codebases, static analysis (clazy) and tooling problems—adding features like inlay hints to CodeBrowser and integrating language support in Compiler Explorer. He combines low-level curiosity (C, x86 basics) with pragmatic UX improvements across front-end and backend work, and has recently extended his toolkit into Rust and Slint LSP contributions. Notably, his open-source patches range from multithreaded process filtering in GammaRay to integrating JSON-based layout persistence in KDAB’s dock framework, reflecting a rare blend of systems thinking and UI sensibility.
