Rockstar🎓
Top SchoolThéo Delrieu is a Paris-based software engineer and co-founder with 10 years of experience building SDKs, developer tooling, and packaging infrastructure for C++ and web platforms. He led design and implementation of multiple Tanker SDKs (C++, iOS, JavaScript), owned their CI/CD, and later contributed as a senior engineer at Doctolib before founding Metal Gear. An active open-source contributor, he has improved cornerstone C++ projects such as nlohmann/json and FunctionalPlus—adding modern meta-programming support and enhanced serialization for user-defined types—and maintains recipes in the Conan Center to ease library distribution. His expertise blends low-level C++ metaprogramming with pragmatic tooling and release engineering, and he often bridges protocol specification, API design, and practical packaging to ship robust developer-facing software.

Aug 2017 - Oct 2017
Functional Programming Library for C++. Write concise and readable C++ code.
Role in this project:
Back-end Developer
Back-end DeveloperContributions:137 commits, 13 PRs, 7 pushes in 1 month
Contributions summary:Théo primarily contributed to the `functionalplus` C++ library by implementing and enhancing its meta-programming capabilities. They added headers like `meta.hpp` and `invoke.hpp`, which included meta-programming constructs and implementations for features like `std::invoke`, `std::is_invocable`, and `std::is_invocable_r`, compatible with older C++ standards. Furthermore, they updated `pairs.hpp` and other related files to facilitate the usage of generic lambdas, enhancing the flexibility of existing functions within the library. This suggests a focus on expanding the functionality and modernizing the library's support for current C++ features.

Contributions summary:Théo primarily worked on refactoring and improving the core functionality of the JSON library. Their contributions involved renaming internal namespaces, updating code to leverage new language features, and adding implementations for alternative serialization methods. The user also focused on improving the library's support for user-defined types by adding enhanced constructor support and incorporating traits for custom serialization.
