What I'm looking for

I’m looking for a full-time role where I can manage projects end-to-end, grow partnerships, and apply analytical problem-solving to deliver measurable client outcomes in a collaborative team.

I’m currently a Business Development | Project Manager in Athens, where I manage incoming project requests and oversee the coordination and delivery of expert engagements—keeping alignment with client objectives from onboarding through execution. I lead onboarding conversations with new clients to ensure project goals match expert sourcing capabilities.

Previously, I’ve built and owned client relationships as a Senior Associate (Client Service Team, Project Manager) and an Account Manager, connecting clients to global experts and supporting daily revenue reporting. I’ve also grown business through sales pipeline management and negotiation as a Sales Manager (remote), and my strong analytical foundation comes from a background in Mathematics, Computational Mathematics, and Numerical Analysis, plus experience teaching and supporting academic work.
