Meet the Leaders
Our core team combines decades of automotive and software expertise. We're passionate about building tools that make mechanics’ lives easier and clients’ experiences seamless.
Loizos Kallinos
Founder & CEO
Loizos is the technical heart of Vehium. With over a decade in the aftermarket automotive space and a deep DevOps background,
he saw first-hand the inefficiencies that garages face and set out to fix them. That journey became Vehium.
As a senior backend engineer at 3AE Health, Loizos also works on full-scale hospital and AI EHR systems, managing highly available deployments and infrastructure pipelines across production environments.
He leads the full cycle: from architecture and containerization to security, scalability, and release automation.
He built Vehium’s backend and infrastructure from the ground up using .NET, Docker, and Kubernetes. He manages CI/CD pipelines, GitHub Actions, traffic routing, encrypted secrets, TLS certs, and rolling deployments.
He also monitors Linux-based nodes and maintains staging, UAT, and production systems with near 100% uptime.
Beyond Vehium, Loizos teaches C# and Unity at Frederick University, supports up-and-coming developers, and finds adrenaline and precision in road and track motorcycle racing.

Alexandros Theodosiou
Co-founder & CTO
Alexandros is the bridge between code and user experience. With a sharp eye for UI and strong foundations in AI and full-stack systems,
he makes Vehium feel clean, responsive, and easy to use whether on web or mobile.
At 3AE Health LTD, Alexandros works on production-ready EHR platforms enhanced with AI capabilities, collaborating with doctors and researchers
to develop next-gen diagnostic and record systems. His MSc in Artificial Intelligence adds depth to the systems he builds.
He has contributed to real-world health tech deployments, including the integration of diagnostic video feeds (e.g., hysteroscopy recordings) into EHRs using voice control,
as well as AI modules for drug interaction warnings and medical imaging insights. Alexandros has presented this work in international conferences across Europe.
His development approach blends technical efficiency with thoughtful design. He’s comfortable switching between backend optimizations, Angular UI fixes,
and React Native animations, all while ensuring everything meets the needs of hospitals, clinics, or busy automotive shops. He believes in building software
that feels invisible to the user because great tech should never get in the way.
