In the following article, I shared a few thoughts on the risks and opportunities for the Greek government, the EU and every citizen. It's clear that we will have to face a lot of difficult decisions in the coming years, in the dawn of a new era which relies heavily on data.
I was very pleased to exchange and share some thoughts with Sotiris Kyriakidis from the Greek news agency “Praktoreio” on how big data can help the current battle against the Coronavirus (Covid-19). It’s the first pandemic (at least in my lifetime), where data scientists or just a data enthusiast can play an important part in how governments handle the Coronavirus crisis. I would be glad to hear your thoughts. (Unfortunately the interview is only available in Greek) Τα «big data» ως τεχνολογικό όπλο για την αντιμετώπιση ασθενειών Εμβόλια, φάρμακα, θεραπείες, έρευνα είναι μερικές μόνο από τις ανθρώπινες δραστηριότητες στον τομέα...
If you have reached a state where the analytics business stakeholders have clearly defined KPIs, spend time discussing website optimization goals and the data collection setup is working consistently, then definitely A/B testing is the next step.
Over the past couple of years, we’ve seen a lot of changes in web analytics and privacy. We saw the release of GDPR and CCPA, the rise of ad-blockers (both in mobile and desktop devices), several releases of Safari’s ITP, Mozilla’s ETP and announcements from Google on similar browser changes in the beginning of 2020. One thing is for sure, the way web analytics was working before is evolving. It does not look like the wild west anymore and there are several rules someone needs to keep in mind when setting up the tracking for a website/mobile app. It’s very...

As part of the 17th digital analytics meetup, which I’m hosting in Thessaloniki, I held a talk on how to use common digital analytics tools to optimize the online experience of visitors. I wanted to show ways a digital analyst can utilize commonly used tools/services in smart ways, which go beyond what is advertised by the vendors. A mature, professional website starts its development cycle several months before its publication, but many may do not know that its development is completed shortly before it is replaced by its replacement (usually several years later). During its “life” there are constantly technical...
Recently I was interviewed by Maria Pantelidou, who is hosting an interesting series of interviews from talented professionals in Thessaloniki, Greece. I was really honored to be among the rest of the great people who already appear in her previous interviews. She gave me the chance to take some time and think about all the decisions and lucky turns in my life that helped me end up where I am. We discussed about the company (baresquare) I am working for the past 11 years, my career in digital analytics and the community for digital analysts I started in my town...

Every mature organization with a digital presence needs to have the right people to be able to support certain tasks with the appropriate analytics roles and complete digital transformation projects successfully. These projects are an absolute necessity if they want to have a data-driven culture in the organization. But which are the roles needed? Analytics is getting more complicated each day, especially in the past few years with the wider adoption of machine learning and artificial intelligence techniques. Talent is hard to find and skills are harder to group under specific job roles/titles. It is important for every organization to...
