Real systems, built with intention. Embedded, connected, intelligent — from robotics to IoT to software that actually runs in the world.
Methodology
Every system starts with a clear process — from the first spark of an idea to a deployed, optimized product.
Concept generation, creative problem-solving, defining the why.
Tech & trend analysis, feasibility, literature review.
System architecture, schematics, rapid prototyping.
Code, firmware, platform integration, QA testing.
Production launch, cloud connectivity, digital transformation.
Performance tuning, smart workflows, AI-driven insights.
Work
A selection of real builds — hardware, software, and systems — each solving a concrete problem.
Swarm Robotics · Collective Intelligence
A critical analysis of decentralized decision-making in swarm robotics systems. Examines how ACO and PSO algorithms fail at scale, why communication is the hard constraint, and why hybrid-hierarchical architectures are the real future.
Arduino-controlled mobile robot with autonomous navigation, line-following, and obstacle avoidance. Full mechatronics integration from sensor fusion to motor driver control — no off-the-shelf stack, everything custom.
Cloud-connected sensor network using Arduino, ESP8266 Wi-Fi module, and DHT11. Real-time temperature and humidity telemetry streamed to ThingSpeak for remote visualization. A complete end-to-end IoT pipeline built from scratch.
Automatic switching circuit using a photoresistor for ambient light detection. Analog signal conditioning, threshold adjustment via trim-pot, and relay-driven load switching. Designed schematic to PCB with full component calculation and simulation in Multisim.
A clean standalone implementation of the Hangman word game built in Visual Basic. No installer required — portable .exe. Greek-language word bank with multiple difficulty levels. An early exploration of desktop application architecture and event-driven programming.
Two small but sharp Python tools. Pomodoro is a terminal-based focus timer using the 25/5 work cycle. AutoSortify automatically organizes your Downloads folder by file type — scans, categorizes, and moves files into labeled subdirectories. Both are single-file, dependency-free scripts.
From Abacus to Tablet — an in-depth technical research paper and presentation tracing the full arc of computing hardware. Covers mechanical calculators, vacuum tubes, transistors, integrated circuits, microprocessors, and mobile SoCs. Published on SlideShare and recorded as a podcast on Spotify.

Feedback
From colleagues and professors who have worked with me directly.
"Ο Alexandros έχει εξαιρετική ικανότητα να συνδυάζει τεχνική ακρίβεια με δημιουργική παρουσίαση. Η δουλειά του στα embedded systems ξεχωρίζει."
"Η συνεργασία μαζί του ήταν άψογη. Πάντα βρίσκει λύσεις και βελτιώνει τις διαδικασίες — ακόμα και υπό πίεση χρόνου."
"Η κατανόησή του για τα βιομηχανικά συστήματα αυτοματισμού και η ικανότητά του να προσαρμόζεται σε νέα περιβάλλοντα είναι αξιόλογη."
