International Office Infrastructure

Designed and coordinated network architecture and standards for international offices — focusing on architecture, security and long-term manageability rather than physical installation.

Context

New offices in New York and Berlin needed consistent, secure and manageable IT infrastructure that fit a global standard rather than ad-hoc local builds.

Challenge

  • Consistent architecture and standards across countries and vendors.
  • Secure segmentation between corporate and guest traffic.
  • Remote coordination of local ISPs and installers.
  • Long-term, central manageability of distributed sites.

My role

Infrastructure architect and delivery coordinator — responsible for architecture, standards, coordination and documentation rather than physical installation.

Responsibilities

  • Requirements analysis
  • Network architecture
  • Equipment planning
  • Wi-Fi planning
  • VLAN design
  • Corporate / guest network separation
  • Firewall & gateway planning
  • ISP coordination
  • Vendor communication
  • Documentation
  • Remote deployment coordination
  • Operational support

Architecture

  • A common global architecture applied consistently to each office.
  • Segmented networks (corporate vs guest) with firewall and gateway controls.
  • Cloud-manageable network equipment for central operations.
  • Documented standards enabling repeatable rollouts at new sites.

Project lifecycle

  1. 01

    Requirements

    Site requirements and constraints captured.

  2. 02

    Architecture

    Global standard adapted per site.

  3. 03

    Planning

    Equipment, Wi-Fi and segmentation planned.

  4. 04

    Coordination

    ISPs, installers and vendors coordinated remotely.

  5. 05

    Deployment

    Sites deployed and validated.

  6. 06

    Operations

    Documented and handed to ongoing operations.

Implementation

  • Equipment and Wi-Fi planned against floor and capacity requirements.
  • Local ISPs and installers coordinated remotely against the design.
  • Deployment validated and documented per site.
  • Operational support model defined for ongoing management.

Documentation & handover

Operational and project documentation were prepared as part of delivery, with handover and acceptance support included where in scope — so the environment can be operated, audited and improved after go-live.

Client names and selected implementation details are intentionally anonymized.

Outcome

Two international offices brought onto a consistent, secure and centrally manageable network architecture, with documentation supporting long-term operations.
