    An e-shop based on PrestaShop+TecDoc* with the following features:

    1. The e-shop communicates with the client's ERP system, synchronizing its product database.
    2. Custom TecDoc search engine
    3. The results of the TecDoc search are merged with the client's products.
    4. In TecDoc results, products that already exist in the ERP can be purchased and the rest can be ordered.
    5. When an online order is downloaded to the client's ERP, there is an intermediate state where:
    • If an order contains only actual products, it is imported in the ERP.
    • In case of the order containing products for order (products not existing in stock), then the client can cancel the order, remove or replace the nonexistant products, automatically create products in the ERP with data retrieved by the database, and complete the process by importing the invoice to the ERP.

    * TecDoc: A joint electronic catalogue for the Automotive Aftermarket that unites different competitors under one roof.

  • ProOffice E-shop (Development)

  • Coffee Ouzounoglou Mobile App (Development)

  • NoveBagno (Development)

  • Marsanis Mobile App (Development)

    A tool for for exporting and importing decoration products in-house using mobile terminals, developed with Kalipso Mobile Development, the bridge application with C# (imports orders in the client's ERP). All data (products and customers) is imported on the mobile terminal so the whole procedure can be sped up. When users want, they can synchronize with the server and refresh all data. When a user fills in an order, he first selects the customer. When selecting a product (through a built-in barcode scanner), the terminal communicates with ERP through web services to receive the price (price lists are stored in the ERP). When the order is completed, it is synchronized in real time with the ERP and the system prints the order automatically. The customer uses 4-5 mobile terminals with no problem at all.

  • Municipality Emmanouil Pappa Mobile App (Development)

    In collaboration with Telesto Technologies Ltd, I implemented a water counter mobile application for the municipality. The solution has two applications, a desktop application and a mobile (Windows Mobile) one. The desktop application communicates with a software called Genesis for retrieving all information of registers in the municipality (name information, address information, counter information and building type). When users measure for the first time, they can retrieve the GPS position of the meter to increase and ease the searching procedure. Using GPS or the built-in barcode scanner (each counter has its own barcode), users can complete a transaction with ease. We developed the mobile application in Kalipso Mobile Development and the desktop in C# using MySQL as the database.
