Preface

Isak Mesihovic

Plate I  ·  Portrait

Infrastructure and security engineer with an industrial IT/OT crossover. Across temporary roles at SKF — manufacturing, logistics, and software engineering — built a full-stack cybersecurity and networking solution for production-environment systems. Designs and operates on-premises zero-trust infrastructure: container orchestration, encrypted backups, monitoring, and multi-service deployment. A background spanning industrial operations, hardware product development, and AI system deployment brings a strong cross-functional understanding of the systems being secured. Currently completing a B.Sc. in Computer Science & Engineering at Chalmers; also runs an independent web and automation studio, shipping self-hosted full-stack applications on owned infrastructure.

Four threads

  1. 01IT/OT crossover — manufacturing floor experience (SKF, 4+ years) alongside a CS degree and ongoing infrastructure work.
  2. 02Hands-on builder across registers — from hardware (e-bikes, CNC, welding) to software (RAG systems, TUI tools, IoT).
  3. 03On-premises infrastructure by preference — production AI stacks, Docker orchestration, zero-trust, monitoring, encrypted backup.
  4. 04Bilingual at native level — Swedish and English — across professional, academic, and technical registers.
