I've been at the computer since its very first day in this country.

Rapid Delivery Power

I was born in Gaziantep in 1989. In 1997 — when I was only 8 years old — my life crossed paths with the computer, and we never parted again. During the infancy of computers and the internet in Turkey, while most people hadn't even heard the word "internet", I was already in front of the screen.

I have spent my entire commercial life in the software and technology industry. From the golden age of ICQ to IRC channels, from Google's arrival in Turkey to the enactment of internet laws, from dial-up modem sounds to fiber infrastructure, from the mobile revolution to the age of AI — I personally witnessed and took part in every critical moment of this country's digital history.

The most valuable thing I learned on this journey: technology is a tool, the result is business. Many people write code, but very few know how code turns into commercial value. I know both. Today, I am fluent in all major languages and technologies of the software world; using technology and my experience, there is nothing I cannot do.

"Experience cannot be bought. It is lived, accumulated, and in the right hands, it turns into the future."— Kahraman Ertan

02 — JOURNEY

Turkey's digital history is my life story.

I wasn't just a witness of each era — I was an active player. Here are the milestones.

1989

The Beginning

I was born in Gaziantep. Nobody knew it yet, but a story that would witness Turkey's digital transformation was starting in this city.

1997

First Computer — The Moment Life Changed

I met the computer at age 8. The internet in Turkey was only 4 years old (METU, 1993). The passion that started that day turned into a lifelong profession.

1998—2001

ICQ, IRC & the Dial-Up Era

ICQ numbers were memorized, mIRC channels were Turkey's first social network. The sound of the 56k modem was the anthem of the internet arriving at home. I was in those channels — not just as a user, but as a learner and a builder.

2001—2005

The Rise of the Web & First Lines of Code

Google arrived in Turkish, the ADSL era began (2003). The journey that started with HTML evolved into real software development. I built my first web projects in this period.

2005—2010

Going Professional & the Internet Law

My commercial software career took off at full speed. I personally witnessed the enactment of Internet Law No. 5651 in 2007, the corporatization of the industry, and Google opening its Turkey office (2009).

2010—2015

The Mobile Revolution

Smartphones changed life; I changed my business. I developed projects spanning from web to mobile, e-commerce systems and enterprise software.

2015—2020

Scaling & Entrepreneurship

From writing code alone to managing teams and companies. I signed dozens of known and unknown projects; each one became the foundation of the next.

2020—Today

Kahraman Holding & the AI Era

I gathered all my experience under one roof: Kahraman Holding. I'm greeting the AI era just like the previous ones — not by watching, but by building. The story continues.

08 — FAQ

Common questions, clear answers.

Who is Kahraman Ertan?

I was born in Gaziantep in 1989. In 1997 — when I was only 8 — my life crossed paths with the computer, and we never parted again. I have spent my entire commercial life in software and technology. Nearly 30 years of knowledge, experience and vision: I didn't just witness it; I built it.

When did your path cross with technology?

1997. The internet in Turkey was only 4 years old (METU, 1993). While most people hadn't even heard the word "internet", I was already in front of the screen. The passion that started that day became a lifelong profession — and it still continues.

Which eras did you personally live through?

I started in the dial-up era — when ICQ numbers were memorized and mIRC channels were Turkey's first social network. I was there for Google arriving in Turkish, ADSL entering homes, Internet Law No. 5651 in 2007, Google opening its Turkey office in 2009, the mobile revolution, and today's AI age. I didn't watch; I built.

Which languages and technologies do you master?

PHP, JavaScript, TypeScript, Node.js, Python, Java, C#, Go, C/C++, Swift, Kotlin, Flutter… The list goes on. But the real point is not memorizing a language: technology changes, languages change — the constant is my speed of learning and building. I don't master one language; I master software itself.

How do we work together?

First I listen: what is your goal, how does your business make money? Then I produce a clear scope, timeline and price. No middlemen, no interns — the person who talks about your project is the person who builds it. Training and support are included at delivery. What they call "impossible" has priority.
