About Nima

I’m Nima, a Senior Web Designer and Developer with 16+ years of experience.
I help businesses turn their requirements into digital solutions that are professional, scalable, and built for real results.

With experience as a founder, in startups, and in large companies like New Yorker, I understand both the technical and business sides of projects.

For me, a website is not just about design — it’s about building trust, increasing visibility, and generating more customer inquiries.

My output is my credibility.
