Oscar Asserlund developed core features for the Kusten-ar-klar-Chas-Challenge-2025/pax repository, focusing on an embedded PAX System for automatic room booking with integrated requirements documentation. He applied a documentation-driven approach, aligning the system’s SRS with evolving hardware and software needs. Oscar enhanced the network communication layer using C++ and JSON, introducing a unified interface for reliable sensor data transmission and implementing security best practices by removing sensitive files from version control. He also stabilized the build process with PlatformIO and updated documentation to reflect hardware changes, demonstrating depth in requirements engineering, system design, and maintainable embedded software development.

Month 2025-05 focused on stabilizing the pax module and aligning documentation with current hardware. Delivered a critical bug fix to improve build reliability and updated project documentation to reflect hardware changes, reinforcing maintainability and clarity for future work.
