01 - ABOUT

“I think like a CTO, move like a startup, and ship like a team of ten.”

- Or Harazi

I'm Or - 24, based in Tel Aviv. I've been building software for 7+ years, specializing in large-scale, complex systems across full-stack, DevOps, and SEO. I hold the CTO role at DOT AI and OneClickTag- both built entirely by me. Every line of code, every architecture decision, every deployment. When you work with me, you're not hiring a developer - you're getting a technical co-founder who executes.

What you actually get

🧠

CTO-level thinking

I don't just execute tickets - I own the architecture, the product decisions, and the roadmap.

⚡

AI-native builder

I ship with cutting-edge AI tools daily - Claude, GPT, Cursor, v0 - and integrate LLMs into products that actually work in production.

🚀

Full-stack × full-speed

Frontend, backend, infra, DevOps. From Figma to Terraform - no handoffs, no blockers, faster than a team.

📈

Technical SEO & growth

Core Web Vitals, crawl architecture, structured data, site-speed optimization. I engineer for search performance, not just user experience.
