Timothy O, Fasanya.
Experienced Cybersecurity Consultant and Network Technician with a proven record in real-time technical support, network migration, and security protocol implementation. Skilled in vulnerability management, network troubleshooting, automation tooling, and advanced threat analysis for monitoring and incident response. Strong capability in data assessment and translating technical findings into actionable, business-aligned decisions. My journey started in a small cybercafé installing and repairing computers. From there, I progressed to leading IT projects, then rebuilt my career from the ground up after relocating to Sweden with no local language and no certifications. Today, as a solution architect, I bring solid skills in cybersecurity and network infrastructure shaped by resilience, continuous learning, and hands-on experience.
Below are a set of security and network tools built around one theme: defending critical infrastructure through SIEM-driven detection, automation, and defense-in-depth.

Career journey

  1. 2002 - 2005

    Customer Service Manager / Engineer

    Starlinks Cyber Cafe, Nigeria

    My first real IT job: troubleshooting and fixing broken computers so customers got a smooth service, one machine at a time.

  2. 2007 - 2010

    Projects Assistant

    Federal Capital Development Authority (Satellite Towns Development Agency), Abuja, Nigeria

    Moved into public sector project support work, learning how larger infrastructure projects actually get planned and delivered.

  3. 2010 - 2015

    IT Project Manager

    Base Global System Technologies Ltd, Abuja, Nigeria

    Nearly six years leading IT projects end to end, from stakeholder management to delivery, before relocating to Sweden.

  4. 2015 - 2019

    Outside IT, rebuilding from zero

    Conference Assistant (Quality Hotel) and Team Lead, General Services (Simplex Bemanning), Sweden

    Moving to Sweden reset the clock: no Swedish language and no official IT certifications meant no way back into IT yet. I took hotel and general services work to pay the bills while learning the language and studying on my own time.

  5. 2019 - 2021

    Network Design and Computer Management

    Halmstad University, Sweden

    Went back to school to earn a Swedish credential and turn years of self-study into something employers here would recognize.

  6. Jun 2021 - Feb 2023

    IT Security & Data Consultant

    Orange Cyberdefense, Malmo, Sweden

    My first cybersecurity operations role: built a real-time Splunk SIEM, onboarded security data from Azure, Google Cloud and AWS, and worked threat detection day to day.

  7. Mar 2023 - Oct 2024

    Network Technician

    Tele2 AB, Gothenburg, Sweden

    Network troubleshooting and Linux systems administration, with automation work in Python to cut down repetitive manual tasks.

  8. Sep 2022 - Present

    Solutions Consultant → Solution Architect (InfraSec)

    Adena Consulting Services Ltd (freelance, concurrent with Tele2)

    Freelance security and infrastructure architecture consulting alongside my full-time roles, advising on cybersecurity strategy, risk management and security protocol implementation.

How these fit together

Each tool below maps to a layer of a defense in depth design: perimeter and email trust (inspect, cert-check), access and identity hygiene (passcheck), policy enforcement (acl-gen), and network segmentation (subnet-calculator). Built, deployed, and monitored the same way I would document and hand off a production architecture: with a clear problem statement, the tradeoffs behind each decision, and a lesson learned, all in the case study linked from every card.
