Hi, I'm Colin.

Technically my legal last name is John.
But Janoshegyi just sounds cooler.


Who I am

I was born in Indonesia, shaped by Cambodia,
and refined in Hungary.

Living across different countries taught me
how people think, choose, and connect.

Today, I focus on marketing, SEO,
and building meaningful ideas.

Professional Profile

A brief overview of my background, experience, and interests.

My work sits at the intersection of marketing, technology, and search. I combine a business background with hands-on experience in SEO and web development, using both strategic thinking and technical implementation to solve problems.

Digital Marketer, SEO Specialist & Front-End Developer

Today, I focus on SEO, content strategy, and web development. I enjoy building websites that are fast, accessible, and genuinely useful for the people who visit them. My work combines technical implementation with marketing strategy, helping brands improve their visibility across search engines and AI-powered platforms.

I’m particularly interested in the future of search, including Generative Engine Optimization (GEO), Answer Engine Optimization (AEO), entity-based SEO, and AI-driven search experiences. As search engines and AI assistants increasingly shape how people find information, I’m interested in how brands can remain discoverable as the rules of discovery change.

My academic background in business administration and marketing at the University of Szeged continues to shape how I approach this work, particularly when it comes to strategy, consumer behavior, and understanding why people make the choices they do.
