Dennis Ngari

I’m a results-driven IT Infrastructure Specialist with 6+ years of hands-on experience managing enterprise IT systems, network infrastructure, security surveillance, and user support. I’ve maintained IT infrastructure for 100+ users across manufacturing and logistics environments, consistently targeting strong uptime and stability.

I configure, troubleshoot, and optimize LAN/WAN networks, routers, switches, and wireless connectivity to keep operations running smoothly. I also implement secure file transfer protocols (SFTP), monitor system performance to prevent downtime, and maintain IT asset registers and lifecycle management to improve procurement and resource allocation.

I strengthen security through surveillance systems and incident response—implementing enterprise-grade CCTV and enforcing IT security policies and access controls for business-critical systems. I deliver Level 1–3 technical support (hardware, software, and network issues), document resolutions into a knowledge base, and provide primary support for business-critical systems including INFOR WMS-related workflows and EDI integrations.

I administer Microsoft 365 and manage 100+ endpoints for reliable remote collaboration and productivity, while developing training materials that improve IT literacy and adoption. I also build digital assets—designing SEO-optimized corporate websites—and I’m proud of impact like a full infrastructure upgrade (35% efficiency improvement) and an automated transport billing system that improved revenue tracking accuracy to 99.8%.
