meet our founder
Konstantinos Ch.
Eleftheriadis
Founder of D.igital t.hinkings
builds infrastructure that stays up
the person behind every project
In 1997… he wrote a numbers game, line by line of code. It still lives on this site and you can play it, try it here. That is where it all began.
Since 1999, from his very first year studying Informatics, he has worked where technology meets people. At 21 he was responsible for the data behind the stock market broadcasts on ET3, Greek public television, a job where every number had to be “right”. Sixteen years followed at the REDESTOS – Efthymiadis group, with SAP ERP and ABAP programming, certifications and administration, at the heart of a large manufacturer. There, IT is not theory. It is the daily operation of an entire production line.
In 2022 he founded D.igital t.hinkings on a simple belief: a company’s technology and the way it presents itself to the world are not two separate jobs. That is why he designs and delivers every project himself, from infrastructure and applications to online visibility.
Today, alongside his own company, he leads digital operations and IT at Kourtidis Group as IT Director. He is the technology person behind one of the largest companies in Eastern Macedonia and Thrace. Twenty-seven years on, what drives him is still the same: taking something complex and making it work simply.
