What I'm looking for
I am a proactive HR systems specialist with over five years' experience delivering HR operations, system administration and process improvement across fast-paced environments. I design and implement workflows, automate manual processes and produce HR MI to support data-driven decisions.
At City Facilities Management I led system configuration, supported a migration to iTrent, reduced support queries through training and self-service improvements, and automated onboarding/offboarding using IRIS Cascade HR and Power Automate. I collaborate closely with Payroll, Benefits, IT and HR teams to optimise processes and ensure data integrity.
I hold an MSc in Human Resources Management and bring technical curiosity—basic knowledge of VB, SQL, Python, JavaScript, HTML and CSS—plus advanced language skills in Greek, English, Spanish and French. I am adaptable, a quick learner and passionate about scalable HR technology solutions.
