Message

At Chubb, I coordinate BAU support and continuous improvement for business-critical EMEA applications. I align business owners, infrastructure, cybersecurity, engineering teams and external providers around service priorities and execution.

I’m the technical and delivery contact for Respond/C7 replatforming and legacy infrastructure retirement. I translate complex objectives into workstreams, dependencies, change plans and operational-readiness actions, and serve as interim project lead on a multi-component enterprise migration.

At Pfizer, I led delivery initiatives across Contract Operations and Contract Insights, coordinating global business and technical stakeholders on automation and process improvements. Earlier, as a Senior Associate, Solutions Engineer, I delivered enterprise data and reporting solutions and built KPI dashboards to improve management visibility.

At CERTH, I contributed to architecture co-design, execution planning and pilot deployments for Horizon 2020 programmes, and developed data-driven and modelling applications. I bring an engineering background, hands-on SQL and Python capability, and native Greek and C2 English.
