Professional summary
Engineering discipline applied to connected industrial environments.
My networking work is the practical extension of a long career in safety-critical manufacturing and product engineering. I am developing the capability to understand, design, analyse, and protect the industrial networks on which modern production depends.
The objective is not to leave manufacturing engineering behind, but to apply its discipline — risk control, traceability, reliability, and managed change — to connected industrial environments.
Industrial networking and OT cybersecurity work
My current practical work combines Cisco routing and switching, network segmentation, Wireshark packet analysis, Python and Pandas automation, virtual network laboratories, configuration auditing, and risk-based engineering methods.
Industrial network design
VLANs, 802.1Q trunks, inter-VLAN routing, Layer 2/Layer 3 EtherChannel, STP, RSTP/PVST+, HSRP, static routing, OSPF, ACLs, DHCP security concepts, and resilient campus/industrial architectures.
Packet analysis and automation
Wireshark traffic inspection, structured packet-data analysis, Python, Pandas, Netmiko, Paramiko, CSV workflows, repeatable reports, configuration auditing, and data validation.
OT security and governance
IT/OT segmentation, industrial-network resilience, defence-in-depth concepts, ISA/IEC 62443 interpretation, FMEA, FRACAS, root-cause analysis, and risk-based decision making.
Virtual labs
Practical design and troubleshooting laboratories using GNS3, EVE-NG, or equivalent platforms to explore network architecture, segmentation, routing, switching, and traffic behaviour.
Career journey
Senior Manufacturing Engineer developing OT cybersecurity capability
Extending more than 20 years of safety-critical engineering, risk management, configuration control, traceability, process governance, and cross-functional technical approval into industrial networking and OT cybersecurity.
Product Engineering and high-reliability systems
Supported development, prototyping, testing, and troubleshooting of high-reliability products, including Ethernet-enabled slip-ring technology and associated data-transfer interfaces. Applied Six Sigma, FRACAS, and root-cause analysis methods to reliability and design problems.
Manufacturing Engineer / Process Engineer
Supported automotive airbag-system manufacturing where dependable performance relied on tightly controlled production processes, risk reduction, standardisation, and production-system reliability.
