Summary
👤
Senior🎓
Top SchoolJens Rehsack is a senior system architect and framework creator with nearly three decades of experience translating business requirements into robust embedded and IoT architectures. A Yocto core contributor and NetBSD committer, he combines deep low-level expertise—kernel, boot firmware and board support work for platforms like NXP/QorIQ and Marvell—with practical CI/CD and platform engineering for distributed teams. He founded the tpo42 methodology to bridge product ownership and architecture, and applies it to regulated industries and inspection systems where compliance and traceability matter. Active in open source (notably contributions to OpenEmbedded/Yocto layers supporting high-performance networking modules), Jens is equally fluent in stakeholder-facing requirements engineering and hands-on firmware troubleshooting. Based in Kerpen, Germany, he is available for system architecture consulting, embedded platform modernization and business-technical translation projects.
