What I'm looking for

I am seeking a data-focused role where I can apply telecom domain knowledge to analytics and machine learning, grow technical skills, and deliver measurable network performance impact.

I am an Electrical & Computer Engineering graduate from the National Technical University of Athens specializing in networks, telecommunications, and optical transmission optimization. In professional roles I design ETL pipelines, ensure data integrity, develop KPIs, and deliver dashboards and visualizations that drive network performance improvements.

My thesis work involved simulation and optimization of coherent optical receivers and contributions to an EU Horizon 2020 project, reflecting strong research experience. I seek to deepen my data science skills and apply AI, machine learning, and big data analytics to solve complex telecom and infrastructure problems.
