Alexis Placet developed and maintained cross-platform C++ packaging and build solutions, primarily for the conan-io/conan-center-index and emscripten-forge/recipes repositories. Over six months, Alexis delivered new Conan recipes and version upgrades for libraries such as Sparrow and ArcticDB, integrating features like SQLCipher-based database encryption and Flatbuffers serialization for Emscripten web builds. The work involved CMake, Python, and Shell scripting to ensure reproducible builds, CI reliability, and secure deployment options. By updating build configurations, managing package metadata, and enabling conditional compatibility, Alexis improved downstream integration, streamlined release management, and enhanced the reliability of open-source C++ package distribution workflows.

In 2025-10, focused on strengthening web build efficiency and serialization performance via Flatbuffers integration in the Emscripten environment. Delivered a new build recipe for emscripten-forge/recipes that enables Flatbuffers, includes Flatc support, and boots memory-efficient serialization for web deployments. The work is backed by commit 04f89f80619c9e517c029047868f68317be1a4cd. Tests were disabled in this recipe to streamline CI; the Flatbuffers library and Flatc executable are installed as part of the target environment, ensuring reproducible web builds.
