AI ENTHUSIAST — BEYOND THE JOB
One of those people who signed up for ChatGPT before it was officially available in Ukraine — registered
using a Dutch virtual SIM just to get access on day one. Since then: continuous hands-on use of GitHub
Copilot, Claude Code, and various AI coding assistants. Actively tracks and integrates new Claude Code
plugins and MCP tools into day-to-day workflow. AI isn't just a tool — it's a genuine interest.
