you do every day.
“Customers keep calling to book.”
Online booking could take care of the calendar too.

BERLIN, DE / ZAFER KAYATHE PERSON DOING THE WORK
Hi, I am Zafer.
I live in Berlin and work as a developer at a cybersecurity company. Over around ten years in IT, I have worked across backends, frontends, mobile apps and the systems behind them.
I especially enjoy solving the tasks that keep taking time out of the day. That starts with listening. How do you work now? Where does it get stuck? What would make it easier?
On your project, you talk directly to me. I plan the implementation, write the code and explain the decisions.
My professional background on LinkedInBEFORE WE TALK
I do not know much about software. Does that matter?
No. Describe what you do today and what is frustrating. I can help turn that into a technical brief.
Can you work on an existing project?
Yes. We look at the code, documentation and open tasks, then agree on a defined piece of work.
Do we have to use AI?
Not always. A simple integration or a clearer interface may be enough. AI is useful when it supports the actual task.
Are the examples former client projects?
The industry examples are newly built demonstrations. Bablio and Puzzlumi are my own products. Both are labelled clearly.
Do you only work with businesses in Berlin?
No. We can work remotely. Calls and project discussions can be in English, German or Turkish.
LET US START WITH SOMETHING SPECIFIC
What would make
your working day easier?
Two or three sentences are enough. What do you do today, where does it take time, and what would you like to change?
We can talk in English, German or Turkish.
