2025 · Next.js 14 / NestJS / Prisma

E‑Exam System

Secure online examination platform with RBAC, scheduling and real‑time updates.
Problem
Online examinations need authentication, strict role separation (Admin, Teacher, Student), scheduling, grading and live updates in one secure place.
What I built
A full-stack application: Next.js 14 and TypeScript on the frontend, NestJS, Prisma and PostgreSQL on the backend, WebSockets for real-time updates, deployed with Docker Compose.
Result
A working, secure exam platform that covers the whole cycle from creating an exam to grading it. It was also my thesis project at AUTH.

2025 · Python / Flask / MongoDB

Custom ERP System

A full-featured ERP platform built with Flask and MongoDB, supporting stock, order, and employee management.
Problem
A business needed one place to run its daily operations: stock, orders, and employee tasks and deliveries.
What I built
With my team, a custom ERP on Python Flask and MongoDB with a RESTful architecture, GridFS for file storage and a responsive HTML, CSS and JavaScript front end, kept modular so it can connect to external services.
Result
Administrators monitor inventory, process and track orders, and see when each order is delivered, all in a single system.

2025 · Python / WooCommerce REST API / Shopify Admin API

E-shop Sync Automation

Full sync (create/update/delete) between WooCommerce and Shopify with custom mapping & safe cleanup.
Problem
A Shopify catalog had to stay aligned with its WooCommerce source: new products, changes and removals included.
What I built
An idempotent Python pipeline that reads WooCommerce, maps products to the Shopify schema and runs a full create / update / delete sync every day from Docker, with SKU as the source of truth, rate-limit backoff and a dry-run before deletions.
Result
A consistent Shopify catalog, always aligned with WooCommerce: no duplicates, no stale items.

2025 · Python / Pandas / NumPy

Greek Parliament Speeches Analysis (1989–2020)

A data analysis and information retrieval project analyzing over 1.2 million speeches from the Greek Parliament (1989–2020).
Problem
1,280,918 Greek Parliament speeches from 5,355 sessions (1989–2020) sat in a single 2.30 GB CSV: too large to read, search or compare.
What I built
With my team, a search engine over the speeches plus keyword extraction with trends over time, similarity between MPs, LSI topic analysis and clustering, served through a Flask web app.
Result
Three decades of political speech became searchable by keyword, speaker or date, with the main topics and the most similar MPs visible at a glance.

E-Commerce Website with Product Sync Script

A custom WooCommerce-based eShop with automated product synchronization via a Python script running on a cloud server.
Problem
An online store whose prices, availability and descriptions depend on a wholesaler's product data, which keeps changing.
What I built
A WooCommerce store with custom CSS and PHP and Stripe checkout, plus a Python script on a Droplet server that fetches the wholesaler's data and updates the products automatically.
Result
The store always shows up-to-date prices, availability and descriptions, without anyone editing products by hand.
