I am building an OT Network Engineer portfolio that connects 20+ years of manufacturing engineering experience with industrial network architecture, packet analysis, Python tooling, and long-term Network Security Engineer capability.
Senior Manufacturing Engineer developing Industrial Networking, OT Cybersecurity & Network Security capability.
About
My background is rooted in safety-critical manufacturing, where reliability, risk control, documentation, change management, and evidence-based decisions are essential.
This portfolio shows how that engineering experience transfers into OT network engineering and cybersecurity: understanding operational risk, designing structured networks, analysing traffic, documenting controls, and building tools that support secure industrial environments.
The profile page brings together my curriculum, practical networking work, education, and the long-term Network Security Engineer strategy.
Read full profile & experienceCore capabilities
Each area supports the same story: manufacturing engineering experience evolving into secure industrial networking capability.
VLANs, segmentation, routing, redundancy, switch design, and industrial network structure.
Risk-aware security thinking for manufacturing, defence, nuclear, and industrial environments.
Wireshark exports, Python/Pandas analysis, packet indexing, validation, and network-performance insight.
Python, Flask, SQLite, Bootstrap, PyQt6, Netmiko, automation, reporting, and governance tools.
Portfolio projects
These projects turn learning into visible evidence: architecture, documentation, tools, packet analysis, and secure engineering workflows.
A Flask-based engineering governance platform designed to structure technical changes, approvals, evidence, risk, and implementation records across manufacturing and OT environments.
Technologies: Python, Flask, SQLite, Bootstrap, authentication, engineering governance.
Read case studyWireshark-exported traffic analysis using Python and Pandas, with packet indexing, validation, and network-performance analysis.
Focus: traffic visibility, structured analysis, repeatable reporting, network behaviour understanding.
Read case studyA PyQt6 and Netmiko desktop tool concept for connecting to network devices, auditing configurations, and producing structured reports.
Focus: configuration review, repeatable checks, documentation, and practical network security workflows.
Read case studyIndustrial and enterprise network design covering VLANs, EtherChannel, STP, HSRP, routing, segmentation, and OT security controls.
Focus: secure architecture, segmentation, resilience, documentation, and defence-in-depth thinking.
Read case studyLong-term direction
The portfolio, documentation, and LinkedIn articles should all support one clear professional direction.
Use 20+ years of safety-critical engineering, change control, reliability, and risk thinking as a strong OT foundation.
Build and document labs, packet analysis, security reviews, Python tooling, and governance workflows.
Publish readable articles that connect industrial experience with network security, OT risk, protocols, segmentation, and practical learning.
Shape the portfolio around security engineering capability while keeping OT and industrial context as the differentiator.
