Welcome to
Stefenos' Portfolio
I'm a server admin who builds things. Log services, small tools, automations, even site templates; as long as it runs on Linux, it's here!

Everyday tools
Tools I'm using almost every day and have experience in
Python
Most of my projects are built in Python, my preferred programming language.
VSCodium
All projects get built here, in the open source and telemetry-free distribution of VS Code.
DBeaver
All database operations, whether it's about MariaDB, PostgreSQL or SQL Server, get done through this database management tool.
LibreOffice Calc
Used to generate charts and apply mathematical formulas on sets of data when researching.
Docker
Used to deploy projects or services quickly and efficiently such as databases, inventory systems and forums.
Debian
Most of the servers and computer systems I manage run Debian or Debian-based distros like Linux Mint or MX Linux.
Research
Research areas
Topics I'm interesting in studying
Digital Ethics / Privacy
Studying system for responsible data use, algorithmic fairness and user privacy.
Archival
Preserving and Organizing Digital or Physical records to ensure accessibility and usability no matter the time.
Artificial Inteligence
Using Narrow (task-specific) AI to design systems that have a limited set of tasks focusing on improving day-to-day life.
Cybersecurity
Studying vulnerabilities, threat models, and defensive strategies to protect digital systems and data.

A selection of my most recent work
PostLogs
A centralized log manager that receives logs via HTTP POST requests and stores them in MariaDB. It applies category-based filtering and sends Telegram notifications for logs matching user-defined critical categories.
CompletedRetrieve LMS
Retrieve-LMS is a learning platform for both educators and learners. This platform will be using Narrow (task-specific) Large Language Models (LLMs) and a Retrieval-Augmented (RAG) System . These technologies will be used for generative and non-generative automations for the platform.

Recent research and writing from me
Building a Learning Management System that integrates Large Language Models and Retrieval-Augmented Generation (RAG)
This thesis will address the asymmetry by covering the design and building of a prototype platform focused on both educators and students alike, providing students with accurate preparation material aggregated by their educators as well as providing said educators with automations that involve Large language Models (LLMs) to make course focused tasks easier to manage.
Implementing Large Language Models on Low-Power Embedded Systems
This paper presents a methodology for integrating LLMs into constrained environments, with a focus on the NVIDIA Jetson Orin Nano. We examine optimization techniques such as 4-bit quantization and knowledge distillation, which significantly reduce memory requirements with minimal accuracy loss.
