About

One specialist.
All of it.

I'm a hands-on technical specialist who takes full ownership of digital projects — from the first commit to the live product. No handoffs, no excuses.

My edge is adaptability. Over five years I've jumped between Linux server administration, Shopify migrations, WordPress management and front-end development — whatever the project needed.

Whether you need a store migrated, a server configured, or a site built from scratch — I show up, learn fast, and deliver.

🔄
Platform agnostic
Shopify, Shoper, WordPress, Linux VPS, Figma — the right tool for the job.
⚡
Full ownership
Backend, frontend, content, marketing — one person, complete responsibility.
📈
Proven scaling
Grew a server from zero to 10,000+ users. I build for growth from day one.
🛠️
Edit & maintain
Fast updates, code tweaks, debugging — flexibility is my foundation.
Experience

Real work.
Real results.
