Experience

  1. AI Security Architect

    Industry
    • Authored an enterprise-scale AI security plan: inventory → shadow-AI definition → visibility → maturity and risk roadmap
    • Built a reproducible prompt-injection corpus mapped to OWASP LLM01 and MITRE ATLAS to evaluate commercial guardrails before adoption
    • Designed a user–asset–data-classification model joining network, endpoint and cloud telemetry into governance and risk metrics
    • ML detection engineering: time series, positive-unlabelled learning and pattern mining for C2 beaconing, DGA domains and compromised hosts
    • Production incident response and root-cause analysis, monitoring design, penetration-test cycles and Kubernetes platform decisions
    • Trained defender teams to design their own prompts and agents for daily operations

  2. Teacher

    Directorate of Secondary Education, Kavala
    Taught first-grade secondary school classes.

  3. Software Engineer (research)

    University of Piraeus
    • Built a prototype index and query engine for spatio-textual big data
    • Prototyped dimensionality reduction combining clustering with hierarchical graph partitioning over spatial data and co-occurrence graphs

  4. Platform Engineer

    University of the Aegean
    • Designed and deployed a data-analytics infrastructure and data fabric for research teams, and presented it to project partners

  5. Computer Programmer & Analyst / System Administrator (military service)

    Hellenic Army
    • Deployed a medium-scale network with Active Directory Domain Services in under a day; set up backup, disaster recovery and user support

  6. Solution Architect & System Administrator

    University of the Aegean
    • Deployed a scalable compute cluster at zero additional cost from open-source tools and idle hardware
    • Enforced access control, encryption and auditing; ran data migrations with minimal downtime

  7. Lab Technical Lead

    University of the Aegean
    • Led labs in object-oriented programming, databases, data structures and discrete mathematics; mentored students

  8. Software Engineer & System Administrator

    University of the Aegean
    • Built a marine GIS routing system optimising vessel routes for fuel, environmental impact and risk
    • Designed the database architecture, optimised retrieval queries and automated testing with Selenium
