Jos Dehaes is a senior software engineer and architect with 11+ years of professional experience and a long history in messaging, connectivity and systems engineering across financial and infrastructure domains. He has deep protocol and backend expertise from long tenures at SWIFT and SunGard, transitioning more recently into Rust and cloud-native microservices at Kraken and Eiger. As a freelancer he blends hands-on coding, system design and cross-team communication, tackling low-level OS integrations (notably improving macOS/OpenBSD support and SMC handling for the popular btop resource monitor). Comfortable across Java, Rust and system-level C work, he brings pragmatic performance tuning and protocol-stack maintainership to complex, high-reliability products. Based in the Antwerp area, he pairs formal training in nuclear physics and artificial intelligence with a practical focus on robust, observable distributed systems.

Contributions summary:Jos primarily focused on improving the macOS and OpenBSD compatibility of the `btop` resource monitor. Their contributions involved adapting temperature sensor readings, addressing CPU core detection issues, and adjusting system calls to correctly retrieve metrics on these operating systems. The user implemented and debugged code related to the SMC (System Management Controller) on macOS, including handling core-specific temperature readings and fallback mechanisms. Furthermore, they made several bug fixes, refactoring, and minor improvements to the code.
