Your Name

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 solutions that combine Generative AI, multi-agent systems, and MLOps best practices to deliver measurable business outcomes. My experience spans research and production engineering — from leading the ImageCLEFmedical 2022 Caption Prediction Task (1st & 2nd place) to building robust, production-grade ML pipelines and AI applications. Skilled in deep learning, NLP, and Generative AI, I leverage Python, SQL, Docker, and Azure to create scalable systems that translate innovation into real-world impact.

Experience

AI Engineer

@ PwC Greece

I design and deploy production-ready multi-agent AI systems and RAG-based solutions across multiple business use cases, enabling context-aware interactions and scalable decision-making.

I architect and implement cloud-native ML orchestration platforms with asynchronous execution, autoscaling, and experiment tracking, ensuring reliable end-to-end AI workflows.

I build end-to-end machine learning pipelines, from data processing and AutoML model training to deployment and lifecycle management, delivering secure and scalable solutions for enterprise and public-sector applications.

I develop and optimize ML-powered REST APIs, enhancing performance and accelerating analytics and operational pipelines while following MLOps and DevOps best practices.

I lead cloud solution delivery, mentor engineers, and collaborate with cross-functional teams to translate complex AI concepts into actionable solutions aligned with business goals.

I also lead the PwC Greece Python Community, promoting clean architecture, best practices, and a culture of continuous learning.
