Stony Stratford, England, United Kingdom
Summary
🤩
Rockstar🎓
Top SchoolRobert Schadek is a research developer with 17 years' experience who solves hard engineering problems by turning them into one-click, maintainable solutions. Based in Stony Stratford, he combines industry research at Symmetry Investments with long-term core contributions to the D programming language ecosystem—working on the D compiler, standard library (Phobos), and core runtime modules. His work emphasizes correctness, testability and performance: converting docs into unit tests, fixing floating-point and time-related bugs, improving BigInt/thread-safety, and pruning deprecated dependencies. He has a strong academic foundation (PhD magna cum laude) and a track record of mentoring and speaking at DConf and Google Summer of Code. Colleagues rely on him for backend and compiler-level expertise that makes complex systems simpler and more robust. An understated but telling detail: many of his contributions focus on making himself obsolete by automating correctness via tests and inline performance improvements.

Contributions summary:Robert primarily contributed to improving the D programming language compiler's core time and bitop functionalities. Their work involved refactoring code by removing and replacing documentation examples with unit tests. They also addressed specific bugs related to the `to()` function and floating-point number handling within the `core.time` module, demonstrating a focus on code correctness and testability. Additionally, the user made several changes to code in `core/checkedint.d` and removed a deprecated feature from `mars.d`.
