Problem

Urban water systems are complex and opaque. Flood risk assessment requires integrating massive sensor networks, hydrological models, and geospatial data into interfaces that non-specialists can act on — in real time.

Role

Full-Stack Developer & Systems Architect at NTUA

Methods

• Hydrological modeling
• Real-time sensor integration
• Geospatial data processing
• Digital twin architecture
• Decision-support system design

Outcome

Developed a Regional Digital Twin for the Attica region, providing a comprehensive platform for urban water infrastructure enabling proactive maintenance and real-time flood risk assessment.

Impact

Deployed as part of the EU Horizon 2020 IMPETUS project across urban water networks, enabling municipalities to shift from reactive to predictive infrastructure management.

Problem

Pest control companies operate via fragmented legacy desktop systems or paper forms, creating massive administrative overhead and offering zero transparency or real-time status reporting to clients.

Role

Co-Founder & Chief Architect (via Metatopia)

Methods

• SaaS Architecture
• IoT Device Integration
• Interactive Floor-Plan Mapping
• Multi-tenant Database Design

Outcome

Designed and delivered the complete PestView cloud infrastructure, including custom multi-view calendar systems and client transparency portals.

Impact

Successfully launched in production, helping pest control operators transition to fully digitized, proactive, and IoT-driven management.

Problem

High-quality immersive films and virtual reality art suffer from a massive distribution problem, rarely reaching audiences outside of major international film festival circuits.

Role

Co-founder & CTO

Methods

• Immersive VR Curation
• Volumetric & 360° Playback Pipelines
• Pop-Up VR Cinema Engineering
• Multi-headset Synchronized Playback

Outcome

Built custom synchronized VR video playback software and portable screening setups, transforming cultural spaces into VR theaters.

Impact

Selected as the first Greek startup in the Cannes Immersive Market Curators Network (May 2026), showcasing international immersive works to general public audiences.

Problem

Complex physical systems — from factory floors to surgical theaters — need spatial interfaces that allow operators to understand, train, and make decisions in context. Traditional 2D dashboards are insufficient.

Role

Co-Founder & CTO at Metatopia / Lead XR Engineer at CERTH

Methods

• Spatial computing
• Real-time 3D rendering
• Multi-user networking
• Sensor-to-twin data pipelines
• VR/AR interaction design

Outcome

Built multiple production XR systems: military VR training (commended by Chief of General Staff), medical VR training (MAGES 4.0), virtual museums, and industrial digital twins.

Impact

Systems deployed in defense, healthcare, cultural heritage, and industrial training contexts across Greece and Cyprus.

Problem

Bridging the gap between research ML models and production-grade systems requires deep understanding of both algorithmic foundations and systems engineering. Most AI work stays in notebooks.

Role

Software Architect & ML Engineer

Methods

• Reinforcement learning
• Deep learning
• MLOps
• API design
• Systems architecture
• Software reusability analysis

Outcome

Authored the official Keras PPO implementation (code-reviewed by François Chollet), published on Hugging Face. Research on software reusability, CNN-based surgical assessment, and ML-optimized wireless communications.

Impact

Keras PPO example used globally as a reference implementation. Research contributions across IEEE and ACM venues.

Problem

Traditional anti-bullying programs lack emotional depth. Building genuine empathy requires experiencing situations from perspectives other than your own — something words alone cannot achieve.

Role

Co-Founder & Lead Developer, Team AMANDA

Methods

• VR immersion design
• Empathy measurement algorithms
• Biometric signal processing
• Multi-perspective narrative design

Outcome

Won 1st Place at Microsoft Imagine Cup World Championship in Seattle ($50,000). Secured a U.S. Patent for the VR behavioral analysis approach. Presented at Microsoft Ignite Conference.

Impact

Pioneered a new category of social-impact VR applications. Demonstrated that immersive technology can measurably shift empathic response.
