Hi, I am
AI Engineer
AI & Machine Learning Engineer with 3+ years of experience designing and deploying intelligent, data-driven systems across Agronomy, Energy Management, Biomedicine, and Public Sectors. At PwC, I develop and scale AI-driven solutions that blend Generative AI, optimization, and MLOps best practices to deliver measurable business outcomes. My background bridges research and engineering — from leading the ImageCLEFmedical 2022 Caption Prediction Task (1st & 2nd place) to building production-grade ML and AI-powered applications. Skilled in deep learning, NLP, and Generative AI, I work extensively with Python, SQL, Docker, and Azure to create robust, scalable systems that connect scientific innovation with real-world value.
Experience
AI Engineer
I design and deploy AI agents, chatbots, and RAG-based systems using Azure OpenAI and Cognitive Search, enabling automated, context-aware interactions and efficient information retrieval.
I build end-to-end machine learning workflows—from data processing to model deployment— delivering scalable and secure solutions for complex public sector and enterprise environments.
I develop and optimize RESTful APIs, achieving up to 70% faster execution and enhancing the performance of analytics and operational pipelines.
I lead cloud solution delivery following DevOps best practices, implementing CI/CD pipelines with Docker, Azure DevOps, and Dev Containers to ensure consistency and reliability across environments.
I collaborate with cross-functional teams, mentor engineers, and communicate AI concepts clearly to technical and non-technical audiences.
I also lead the Python Community at PwC Greece, promoting best practices and continuous learning across the organization.
