Ilja Nedilko

System Engineer, Proud dad
Location: Maardu, Estonia | Age: 33 | Languages: English, Swedish, Russian

My name is Ilja Nedilko, I am a self-taught, seasoned IT tinkerer with over 15 years of experience. I have worked in a variety of roles, including application support, workplace services, end-user experience, web development, and systems administration.

I have a heavy bias toward the Microsoft stack and services, but I'm also a big fan of Linux. I'm obsessed with automation, telemetry, and reproducible infrastructure. I treat environments like code, logs like truth, and outages like puzzles. I'm a fast learner devoted to intelligent and scientific technologies and continuous improvement. I'm passionate about automation, a reliable user experience, and pragmatic engineering.

In practice, I:
Build and support web applications and middleware stacks (PHP/NGINX/IIS) on Windows and Linux.
Tune DB backends (MySQL, Postgres, MS SQL, SQLite, DuckDB).
Design and operate Windows and Linux infrastructure; automate provisioning and patching; and script complex workflows using PowerShell, Bash, and Python.
