Hello, I'm Kostas
I am a software developer. I build websites and mobile apps for anyone with an idea they want to see working.
I studied at the Department of Digital Systems of the University of Piraeus, where I earned both my bachelor's and my master's degree.
Since 2020 I have been designing and building mobile apps, websites and web apps. I work with businesses, associations, professionals and individuals, and I talk to each one directly, from the first conversation to the day the work goes live.

What would you like to build?
A website that opens fast, looks right on a phone and explains within a minute who you are and how to reach you.
- Designed around your own identity
- Your own address name and professional email
- Set up so people find you on Google

Don't take my word for it. Open one:
