What I'm looking for

I'm looking for a role where I can apply research, analytics, stakeholder communication, and process improvement to deliver measurable outcomes in HR, operations, education, or customer-focused teams.

I'm currently supporting executive search at Dr. Pendl & Dr. Piswanger Romania, where I source, qualify, and place candidates using LinkedIn Recruiter and Ezekia. I contributed 35% of required monthly hires, reduced time-to-fill by 30%, and exceeded client DEI and offer-acceptance metrics.

I've also taught statistics and data science at the University of Bucharest and SNSPA, using Excel, SPSS, Stata, and R to strengthen student learning. My curriculum redesign increased project submissions by 60% and exam scores by 36%, while my mentoring supported more than 40 students with thesis preparation and research papers.

Across customer support, public administration, and education operations, I've delivered process improvements, reliable research coordination, and stakeholder communication. At Qualitest, I reduced ticket resolution time, churn, and onboarding time while improving customer satisfaction, team productivity, and first-call resolution.
