About

I am a Senior Manager of Software Engineering at Diligent, leading two teams across interconnected projects and partnering with teams whose technical backgrounds and maturity vary widely.

I co-lead the Budapest AI Ambassador program, responsible for propagating knowledge to all engineering teams and helping AI Adoption through Ambassadors as representatives of each team.

I am deeply involved in recruitment organization-wide, and I led our internship program in 2025.

Beyond work hours, I have been running a monthly book club for three and a half years to help build our company culture.
