Summary
👤
Senior🎓
Top SchoolDenis M is a seasoned Linux engineer and founder of itcostnipper.tools with over two decades of hands-on experience optimizing bare-metal infrastructure and cutting IT costs without sacrificing capability. He has a proven track record at high-scale environments—lowering cluster load dramatically through NUMA and kernel tuning, hardening exposed infrastructure, and restoring stability under production pressure. Comfortable from kernel internals to automation, he scripts in Python (and Ruby historically), builds tooling, and routinely diagnoses subtle issues like zombie processes, file-descriptor-held disk usage, and OOM behavior. His background spans running global game and web platforms, managing multi-datacenter operations, and delivering R&D that reduced costs and unlocked tax incentives. Now consulting for enterprise clients, he blends deep systems expertise with architecture and vendor advisory to find hidden waste and hard-to-see performance gains. Based in Almere, Netherlands, he’s known as a reliable, curious engineer who prefers digging into system internals rather than relying on surface-level metrics.
