Katalin Kostenszky

I've supported senior leaders at ExxonMobil's Mozambique Rovuma LNG Project, Mellitah Oil and Gas, Erste Bank Hungary, and consulting businesses across complex international operations.

I manage executive diaries across time zones, coordinate high-stakes travel and visas, prepare leadership communications, and act as a trusted point of contact for senior stakeholders. At ExxonMobil, I supported three senior managers, produced weekly personnel and business-activity reports, and helped develop logistics software supporting security compliance for deployed staff.

In my current virtual executive assistant role at JECD Consultancy, I coordinate executive scheduling, create business documents and presentations, and manage invoice processing and financial reconciliation. Previously at Positive Momentum, I supported six Senior Partners with diary management, project and business development support, travel, invoicing, reconciliations, and DocuSign workflows.

I'm comfortable working independently in remote, fast-changing environments while bringing discretion, calm judgement, and proactive support to executive teams across cultures.
