About Me

I am a network & security consultant focused on helping organizations design, build and maintain secure, reliable and well-documented network infrastructures. My main technology stack revolves around Cisco, Fortinet and Palo Alto Networks.

Over the years I’ve worked on projects ranging from small branch rollouts to complex data center migrations, VXLAN/EVPN designs, and multi-vendor firewall transformations. I enjoy solving difficult problems, simplifying legacy environments, and leaving behind clean designs and solid documentation.

Network Security Consultant

  • Based in Europe (remote-ready
  • Projects across multiple industries
  • Available for short-term & long-term engagements
  • English-speaking, documentation-driven

What I Do

Architecture & Design

High-level and low-level designs for data center, campus and branch networks: segmentation, VRFs/tenants, secure Internet edge and VPN architectures.

Migrations & Transformations

Planning and executing migrations between firewall platforms (Cisco ASA/Firepower, FortiGate, Palo Alto Networks), including object/rule conversion and phased cutovers.

Operations & Optimization

Rulebase clean-up, logging and visibility improvements, troubleshooting, performance tuning and automation using scripts and APIs where possible.

Vendor Focus

I work across multiple platforms and usually act as the “glue” between network, security and operations teams. My main areas of expertise include:

Palo Alto Networks

  • Design and operation of PA-series firewalls
  • Panorama-based centralized management
  • App-ID, User-ID and threat visibility
  • GlobalProtect remote access VPN

Fortinet FortiGate

  • FortiGate NGFW (incl. VDOMs & HA)
  • FortiManager & FortiAnalyzer integration
  • IPsec & SSL VPN, SD-WAN
  • Segmentation and micro-segmentation

Cisco ASA / Firepower

  • ASA/FTD rulebase and NAT design
  • Site-to-site and remote access VPN
  • Integration with Catalyst and VXLAN/EVPN
  • Gradual migration to next-gen platforms

How I Work

Pragmatic, Transparent, Documented

I prefer to work in a very transparent way: clear scope, realistic timelines, and regular updates. Every engagement is backed by documentation: diagrams, design decisions, implementation steps and operational procedures. This ensures that your internal team can support the solution comfortably after the project is completed.

Typical Engagement Steps

  1. Discovery: current state review, requirements and constraints.
  2. Design: high-level and low-level design documents.
  3. Implementation: lab testing, pilot and production rollout.
  4. Handover: documentation, knowledge transfer and optimization phase.
