Contributed to the design and implementation of a KG-driven validation pipeline for Retrieval-Augmented Generation (RAG) systems. Developed mechanisms for semantic triple validation, entity consolidation, and Knowledge Graph verbalization to support answer verification and hallucination reduction in LLM-based QA systems.

Designed and implemented the webpage of the Dancing Group "Alios" Corfu using HTML, CSS, and JavaScript by utilizing AI tools. Accessible via www.alios-corfu.com

Designed and implemented a Geographical Information System (GIS) platform as an extension of the work "Analysis of the 'focus' and 'sentiment' of restoration interventions in the aquatic domain" which takes as input a data file (.mra file) from the tool presented in the paper and shows its contents on a live map. Implemented using ReactJS, MaterialUI and ArcGis.

Designed and implemented a statistics component with data visualization (bars, pies) using ReactJS and MaterialUI. Developed a barcode generation service using Java for PDF outputs.

Analyzed and designed a platform for hosting E-Sports events and their content, as a CS351: Information Systems Analysis and Design course project. The platform was partially - as requested - implemented, and fully evaluated. The implementation was made using React-TS, Docker, HTML5/CSS, and Material-UI. The evaluation was made using W3 Validator, Wave, Lighthouse and Heuristics.

Implemented an information retrieval system that can index and answer queries on a corpus of 2.5GB consisting of medical research articles, as a CS463: Information Retrieval Systems course team project. The system was also evaluated using various metrics. The implementation was made using Java and Python.

Created a web platform for the Fire Department allowing incident submission & management, user sessions, communication, and more, using HTML, CSS, JavaScript, OpenLayers Maps, Bootstrap, JQuery, and other libraries as a CS359: Web Development course project.

Created a compiler for the Alpha programming language using C, Flex, and Bison. The compiler compiled Alpha code to execute on an Alpha Virtual Machine.
