Projects

Some of the things I've been involved in:

PPH Data Pipelines
I created several data pipelines on AWS in order to handle the updates of the data the Data team use in their daily operations. Using Lambda, Glue and Step Functions these pipelines are designed to make debugging and extensions easy for the developer and also notifications and fallbacks are in place for when things -inevitably- go wrong.
  • Laravel / VueJS
  • MySQL
  • ArcGIS
OPTIMA (Decision Support System)
The goal of the OPTIMA project is to provide a holistic solution for pest management in specific types of crops. As the main software engineer, responsible for the Decision Support System's development (part of the AGENSO team), I designed and developed all the components such as the database, the system architecture, the admin panel and the frontend application. The DSS is designed to provide alerts in the form of the probability of infection from certain enemies of crops, to help the farmers make the correct decision when spraying their farms. The project is funded by Europe's Horizon 2020 programme and the consortium is comprised of major European universities and companies active in the agricultural sector.
  • Laravel / VueJS
  • MySQL
  • ArcGIS
Effispray
To solve the problem of inefficient spraying in the fields, we developed EffiSpray. Using ArcGIS and a prediction model developed by AGENSO, I designed and developed the web application with Laravel. The application shows a map of Greece coloured by area depending on the calculations made using AGENSO's predictive model and weather forecast data retrieved from an external API.
  • Laravel / VueJS
  • MySQL
  • ArcGIS
PAMCoBA (Precision Agriculture – Methods for Cost and Benefit Analysis)
The purpose of this web application is to help farmers invest in the right technologies for their farm. By analysing their farm and the operations they want to apply the users get the analysis and can download a specialised report. My contributions were centred around the database design, according to the specifications, and the software development as the main software engineer. This project was funded by the ICT-AGRI programme and is a cooperation between the University of Copenhagen, Agroscope, the University of Bologna, and AGENSO.
  • AWS Glue, Step Functions, Lambda, Redshift
Winagro Cloud
Web application for one of the leading agricultural equipment suppliers in North Greece. As the main engineer on the project, designing and developing the application was the task at hand. The purpose was to gather data from the application's users and then use them on preset templates supplied from the Greek Ministry of Agriculture. The generated documents were then submitted by Winagro's clients to apply for agricultural funds.
  • LAMP stack
  • Laravel
  • PHP Office
socialight.biz
We created a web application for IPG Mediabrands dealing with the data they gathered from their corporate clients' facebook pages. I developed the data retrieval/storage from the Facebook Graph API and the data manipulation in the frontend using Google Charts.
  • LAMP stack
  • Custom PHP MVC-like Framework
  • Facebook Graph API
  • Google Charts
E-Commerce Projects
Some of the Magento projects I took part in as a developer and later as the support team leader. All of them were custom designed and as part of the development team I created many custom modules to extend the functionality of the framework.
  • Magento 1: tsakiris-mallas.gr, galeriedebeaute.gr, housebox.gr
  • Magento 2: parex.gr, casa39.it, migato.com
