Hi, I'm Iury Nícolas
Data and Network Engineer
Incorrect data is not just a nuisance, it is a threat to the survival of any operation. Organisations collect more data than ever before, but 70% of analytics initiatives fail due to poor data quality, and this can be an analogy for all types of activities, as solving problems involves a great deal of understanding and root cause analysis.
I am an experienced technology professional, but I know that it is never enough, and I am always learning. I began my journey as a technical assistant and, through experience and knowledge acquired, I grew within the companies I worked for. With experience ranging from the field to the server, I was able to acquire skills involving various types of systems, networks and integrations, as explained below, such as general use of tools, installation, general CCTV and commitment to company policy.
About Me
Network and telecommunications professional with 8+ years of experience in infrastructure deployment, network management systems and IT operations support. Strong background in GPON, fibre optics, structured cabling and wireless networks, combined with experience managing large-scale IT projects across multiple sites.
With a proven track record in optimizing data integrity, I specialize in transforming networks and systems to ensure accurate and actionable information. My approach focuses on providing strategic visibility for decision-making, driving tangible growth in business performance.
