His workload demonstrates a consistent focus on the interface between public authorities and private sector participants, including infrastructure, energy projects and large-scale tender procedures.

A core element of Avgouleas’s professional profile is his leadership in high-stakes public-law matters.

His work routinely involves advising on tenders, bid defenses, and post-tender disputes, as well as defending clients in complex regulatory challenges before administrative courts and EU-influenced processes.

Avgouleas has also been involved in several landmark matters that underscore his role in the Greek public procurement and infrastructure sphere.
