Summary
🤩
RockstarMathieu Lonjaret is a pragmatic software engineer with 16 years of experience building back-end systems, devops tooling, and scientific software, currently contributing to conservation-focused Arribada Initiative. He has deep Go expertise demonstrated by meaningful contributions to high-profile projects like Traefik (core proxy features, Kubernetes provider fixes, ACME/TCP support) and the Yaegi interpreter, plus robustness work on goexif. His background blends research-grade scientific tooling (radioastronomy and ALMA data reduction) with production cloud-native engineering, giving him fluency across C/Fortran, Python, Java and modern Go ecosystems. Based in rural Auvergne, he prefers mission-driven roles in science or environmental protection and brings a knack for untangling legacy systems and improving maintainability. A detail not obvious from titles: he’s comfortable operating at both low-level data handling (EXIF/TIFF robustness) and high-level infrastructure concerns (IngressRoute behavior and TLS automation).
