I build enterprise GenAI, machine learning, and data platforms, currently working as a Machine Learning Engineer at IQVIA after progressing through Data & AI Engineering roles at IBM.

At IBM, I co-designed and delivered a telco GenAI assistant that generates personalized marketing campaign messages, helping reduce time to market and improve productivity. I also led data engineering and governance delivery across telco and gaming, including DWH customer-behavior data, financial reporting, Collibra automation, and metadata ingestion.

My earlier R&D work at NCSR DEMOKRITOS focused on computer vision and human activity recognition in video. I developed a multimodal hybrid Vision Transformer/CNN architecture for egocentric action recognition that led to a peer-reviewed journal publication.
