SUBSYSTEM // hardware [ 01.A ]

Currently a Field Electrical Engineer at Kourtis Tech — on-site installation, commissioning and systems integration across diverse projects. Earlier at Kapa Install I optimised technician scheduling, managed the e-shop infrastructure, and led R&D into emerging electrical systems. Foundation: a BSc in Educational Electrical & Electronic Engineering from ASPAITE — circuit design, digital and analog systems, embedded systems, telecommunications and networks.

Former SOC L1 Analyst @ Adacom · eCPPT · TryHackMe SAL1

SUBSYSTEM // detection [ 02.A ]

At Adacom (2025 – April 2026) I monitored client environments daily, triaged L1 alerts and executed incident playbooks to contain real threats — working closely with security teams and system owners. Alongside this I built and still maintain a functional SOC lab around Wazuh SIEM on Linux: endpoint log forwarding, custom detection rules, brute-force and suspicious PowerShell investigation.

MODULE_03 // BROADCASTING

The Educator.

Private Tutor (2021–2025) · Web Developer @ Core Concepts

SUBSYSTEM // pedagogy [ 03.A ]

Since 2021 I've taught secondary, high-school and tertiary students in Electrical Engineering — in person, remotely, and at tutorial centers. I built and maintain a Greek educational platform to scale that work, and I bring the same teaching instinct into every technical handover and documentation sprint.

MODULE_04 // FEATURED PROJECT

EduPlatform Greek Education SaaS

A multi-tenant B2B tutoring platform I built for private tutors and small educational centres (φροντιστήρια) in Greece. Teachers manage courses, chapters, lessons (video, rich-text, PDF, quiz), live Zoom rooms and track per-student analytics — all scoped to their organisation via Firestore security rules.

LIVE DEMO

Open Live Demo ↗ Source on GitHub ↗

🔒 eduplatform-1-pilot.netlify.app ↗

Students learn, track, and join live sessions.

› Sign up with an organisation invite code — auto-scoped to that org
› Choose school type, grade, orientation and sector (full Greek education system)
› Browse courses filtered by grade
› Watch video lessons, read theory (rich text), view PDFs in-browser, and take multi-choice quizzes
› Progress tracking per course with completion percentages
› Quiz retries with full answer review and explanations
› Join live Zoom rooms scheduled by the teacher
› Profile settings with instant dashboard refresh · password reset via email

Teachers build content and track analytics — end to end.

› Builder Pro admin panel: Courses → Chapters → Lessons → Live Rooms
› Upload content in 4 formats: 🎥 Video · 📝 Rich Text · 📄 PDF · ❓ Quiz
› AI-powered quiz generation (3/5/10 questions) via Google Gemini
› AI theory writing — generate lesson explanations from a prompt
› Cascade delete: chapters → lessons → progress → live rooms
› Quiz builder with drag-to-reorder, 4-choice questions, correct-answer marking
› Schedule and manage live Zoom / Teams / Webex rooms per course
› Analytics dashboard: student count, completions, quiz averages, per-course progress bars, searchable/sortable student table

Super Admin governs the platform across organisations.

› Cross-organisation access to all data
› Promote users to admin role
› Create and manage organisations with invite codes
› Suspend / reactivate organisations
› Override any security rule (Firestore rules bypass)
› Full audit visibility across every tenant
