Nikolaos Efstathiou

Digital Communication & Audiovisual Content Specialist

I design and deliver digital communication projects for the public sector: from concept and script to video production, graphic design, web publishing, UX and accessibility. Below is a selection of my recent work in audiovisual production, graphic design, digital campaigns and web experience.

About

I am a Digital Communication and Awareness-Raising Expert at the National Transparency Authority of Greece, where since 2020 I have been creating and managing digital content, websites and audiovisual campaigns that promote transparency, integrity and citizen engagement. Previously, I worked at the Hellenic Broadcasting Corporation (ERT S.A.) in IT and digital broadcasting roles, and I have long-standing experience as a certified adult educator in informatics.

My work combines audiovisual production, graphic design, UX & accessibility, web management and digital campaign strategy. I am experienced in collaborating with multidisciplinary teams, contractors and international partners, and in aligning communication outputs with EU-level standards and procedures.
