Short bio
Hello! 👋
I am Stelios, or Stylianos, as my ID insists. I graduated - survived from the Department of Statistics and Insurance Science, completing all 47 courses. Even though I didn’t receive the legendary A38 certificate, I did get my completion certificate, and I am moving forward!
I have a strong passion for data analysis, machine learning, and more recently, deep learning. Right now, I am looking for my first job in Statistics or Data Science, either in a Junior position or through an internship. No matter when this small miracle happens, I will be here doing what I love. Until recently, I was heavily focused on R, but since I need to find a job, I have started learning Python more systematically. During my studies, I completed many assignments using LaTeX, which is a tool similar to Word but mainly used for work with heavy mathematical and statistical notation. In addition, in my free time, I enjoy creating various visualizations, writing analysis articles, and building statistical web applications like dashboards and ML apps. Many of these can be found on my website.
Happy reading!

Skills
Programming
Πιο μεγάλη εμπειρία έχω με την (Rstats), μιας και έχω δουλέψει σε διάφορα prοject ή εργασίες για τη σχολή. Τη χρησιμοποιώ από το 2018 και η εξέλιξή μου και το επίπεδο άνεσης μου έχει βελτιωθεί σημαντικά. Αποτελεί μέχρι και σήμερα τη πρώτη μου επιλογή γλώσσας για προβλήματα ανάλυσης/οπτικοποιησης δεδομένων ή μηχανικής μάθησης. Επίσης, τον τελευταίο καιρό έχω αρχίσει να μαθαίνω Python, μη μπορώντας να αγνοήσω την ουσιαστική της κυριαρχία στο πεδίο της επιστήμης δεδομένων κυρίως λόγω των εφαρμογών της στη βαθιά μάθηση. Έχω φτάσει σε ένα ικανοποιητικό επίπεδο αρκετά γρήγορα, αν και έχω πολλά να μάθω ακόμα. Ακόμα πιστεύω ότι η R είναι η ιδανικότερη γλώσσα για την ανάλυση δεδομένων και για τη μηχανική μάθηση. Πέρα από αυτά
Tools
Όντας κυρίως ένας R προγραμματιστής τα κύρια πακέτα που θα χρησιμοποι είναι τα μεταπακέτα tidyverse και tidymodels. Συνεπικουρικά μπορεί να χρησιμοποιηθεί και κάποιο άλλο πακέτο αναλόγως την πολυπλοκότητα της εργασίας που έχω αναλάβει.
- tidyverse
- tidymodels
- modeltime
- rvest
About this website
My first attempt at creating a website was in 2022, using Distill, a popular R package that makes it easy to build a simple website. As you might expect, it was widely used by those familiar with R. Around the same time, Quarto was released, and I switched to it a few months later. Since then, I’ve been using Quarto exclusively for my website.
One important addition worth mentioning is the babelquarto package, which enables the website to support two languages (Greek and English). Because of the bilingual setup, I needed to choose a font that supports both Greek and English characters so that switching languages wouldn’t affect the typography. That’s why I use Gentium Plus throughout the website.
During the first year of my website’s operation, I used the free domain provided by GitHub, which was stesiam.github.io. Some older content, especially in the gallery collection, still references this original domain in diagrams from 2022. In 2023, I decided to give the website a more professional identity by purchasing my current domain name. Since the beginning, the site has been hosted for free through GitHub Pages.
