From zero
to the cloud.

Left Türkiye at 17. Built a life in a new country through technology. Then started building the cloud itself.

Scroll the journey
Chapter 01

Where it all began.

Istanbul, Türkiye · 2013–2017

I was fascinated by computers — by creating something with nothing more than an idea and a keyboard.

I chose a technical high school and studied database systems. At 16 I was interning at Metro Istanbul, writing C# for the ERP team and tuning SQL queries.

I didn't know where the path would lead. I knew I wanted to build things.

Chapter 02

17. A different world.

Türkiye → Poland · 2017

At 17, I made a decision that changed the direction of my life. I left.

A different country, a different culture, a different language. Everything familiar was suddenly somewhere behind me.

I began with preparatory studies at Warsaw University of Technology. That move was more than a change of location. It was the beginning of independence.

Chapter 03

Learning to create.

Warsaw · 2018–2020

Programming became a way of thinking.

I studied Computer Science at the Polish-Japanese Academy of Information Technology. But I wanted more than assignments — I wanted to make things people could actually use.

Databases, backends, web apps, mobile apps, datacenter floors. Every problem became something I could break down.

Chapter 04

From code to business.

Technox · 2016–2021

I co-founded Technox, a hosting and datacenter services platform.

I was no longer just writing code. I built the customer-facing site, WHMCS plugins and the automation behind them — and learned what it means to own a product.

Chapter 05

The professional journey.

Kraków · HCL · 2020–2025

Five years of enterprise software, from IT analyst to Software Engineer.

SaaS products, frontend engineering, performance work, codebase modernization across teams.

90%shorter builds
50%faster page loads

These years taught me how software is built at scale.

Chapter 06

Building something of my own.

TheyCloud · 2023–present

I didn't only want to work with existing platforms. I wanted to build one.

Compute, networking, storage, billing, DNS, monitoring and automation — a white-label cloud platform, designed and built from the ground up.

250k+lines of code
124+REST APIs
354domain events
50+database tables
Chapter 07

The story continues.

Kraków · Pegasystems · 2025–beyond

Today I work as a DevOps Engineer at Pegasystems.

AWS, Terraform, Kubernetes, developer platforms. And the same curiosity that started in a database class in Istanbul.

I still want to understand how things work. I still want to build better systems.

Not the end

Keep learning.
Keep building.

The most interesting things are the ones that haven't been built yet.
