About Me

From technical sales to infrastructure architecture

Experience & Transition

The Professional Edge

Currently working in technical sales, I have developed a sharp focus on problem-solving and high-pressure environment management. My background in spare parts sales has taught me how to navigate complex systems and provide clear, technical solutions to clients—skills I am now translating into a career in Information Technology.

As a Computer Science student at the University of Turku (expected 2027), I balance academic theory with intensive practical application. I am driven by a passion for designing secure networks and understanding the underlying architecture of modern cloud environments.

The Builder's Mindset 
I don't just learn from books; I build.

My daily routine involves managing a 
production-grade home lab where I experiment 
with:
  • Virtualization (Proxmox)
  • Network segmentation (VLANs)
  • Automation (Ansible, IaC)
  • AI/LLM deployment

My immediate goal is to secure a role in 
Help Desk, ICT Support, or Junior SOC 
operations to apply my skills in a 
professional environment while progressing 
toward Cloud Security Architecture.
