About us

A small studio with a builder's mindset

DigitalMind.Works is an independent software studio founded by Duygu Tanker and Mert Tanker. We craft our own products, like hesapbol.app, and partner with founders and companies who want the same care in theirs.

No middlemen, no endless meetings. Just a lean team that writes code, ships things, and answers your messages.

Our story

Our founders and our approach

DigitalMind.Works was founded in 2022 by Duygu and Mert Tanker. The studio combines more than two decades of engineering experience with a disciplined approach to product design.

Mert Tanker began his software career in 2000 and has since accumulated more than two decades of engineering experience across web, mobile, and backend systems. His work is defined by a commitment to clean architecture, performance, and lasting reliability.

Duygu Tanker spent the early part of her career in Turkey's aviation sector, where operational precision, systems thinking, and composure under pressure are essential standards. She brought that discipline into software, where it now shapes the look, behaviour, and overall quality of the studio's products.

The two founders established a shared practice in 2022 and soon began collaborating on commercial software products. Their first release, hesapbol.app, was developed during this period and is now available on iOS, Android, and the web.

That first product grew into a studio. Today, DigitalMind.Works operates as an independent software company, partnering with clients on web, mobile, and design engagements while continuing to develop and support its own portfolio of products.
