What I'm looking for

I seek roles where I can build scalable ML-driven systems, optimize data pipelines, and work in collaborative teams that value performance and research-informed engineering.

I am a software engineer and data scientist with an MSc in Data Science and Information Technologies and a BSc in Informatics and Telecommunications. I build scalable backend systems, data pipelines, and machine learning models that deliver measurable performance gains.

At CNH I led development of geospatial image distribution, portal notifications, hardware-registration APIs, novel data processing algorithms, and API testing infrastructure, improving processing efficiency by 75% and reducing query times by 30%.

Previously, I developed speech technologies and deployed model pipelines at scale at Athena Research Center, contributing speaker diarization and training advanced ML models for Greek language and speech applications. I have hands-on experience with cloud services, containerization, and infrastructure tooling.

I enjoy solving production-scale engineering problems, optimizing system performance, and applying ML to real-world language and data challenges. I publish in the speech-processing field and contribute to open-source and research projects.
