Süleyman Altuntop sitting on a chair

Hi, I'm Süleyman.

I'm a web and mobile app developer. I do the design, the code and the testing, so the same person can tell you why something is late and why it's safe.

I'm a perfectionist. If one button is out of place, the work isn't done.
Süleyman Altuntop, founder, altuntop.dev

I build web and mobile apps end to end with Next.js and Flutter. I've shipped products as different as bookkeeping for small shops, a password vault, a fishing channel's website and an exam-prep app.

I treat software as something you can try, not a claim. That's why every product is live, and how it's built and where to find its privacy information is written on its own page.

Every project goes through the same six checks before it ships. If one fails, it doesn't ship. That rule saves time for both of us.

What I've shipped

How I think about the work

Understand first

Before choosing a solution I talk about who wants what and why. I don't build features nobody needs.

Less data

No unnecessary data is requested. How collected data is handled is written in the product's privacy notice.

Decide by measuring

Speed and accessibility are measured, not guessed. I don't write claims I can't put a number on.

The code is yours

Delivered code and documents belong to the client, so you're never locked in.
