Summary
👤
Senior🎓
Top SchoolRichard Scheffenegger is a networking and storage-focused engineer with over a decade of hands-on experience optimizing performance across OS, networking and storage stacks. As a FreeBSD committer and long-time NetApp architect/consultant, he blends kernel-level TCP feature work (DSACK, PRR, Cubic, ECN) with pragmatic storage performance and datacenter design. He chairs and authors IETF drafts and RFCs, bringing protocol-standardization influence to practical deployments and product strategy. Known for translating complex technical tradeoffs into business decisions, he combines deep systems troubleshooting with pre/post-sales and CTO-office advisory experience. Based in Vienna, he pairs an MSc in IT Consulting with a background in technical chemistry—an uncommon mix that fuels his analytical, cross-disciplinary approach.
