Data space specialist with 20+ years of software architecture behind it.
I design, build, and operate dataspace connector infrastructure based on Eclipse EDC β one of the few freelancers in Europe with hands-on, production-grade EDC experience beyond the tutorials.
What I deliver in the data space domain:
- EDC connector deployment and operation on Kubernetes: PostgreSQL persistence, HashiCorp Vault, multi-cluster setups, Terraform-automated infrastructure
- Custom EDC extension development: event-driven data push, policy and credential evaluation functions, catalog integrations
- Decentralized identity: Identity Hub, verifiable credentials, DID-based trust setup, cross-cluster trusted-issuer configuration
- Participant/partner onboarding into running dataspaces, end to end: credentials, policies, contract definitions, connectivity
- EDC version upgrades and migration (incl. 0.1x line, Data Plane Signaling)
- Second stack: FIWARE data space connector (F-DSC) and NGSI-LD β including comparative architecture assessment of both ecosystems
Current engagements include the data space for an EU Horizon CCAM mobility project across seven European pilot cities, a battery-value-chain dataspace, and logistics data spaces β all Gaia-X / IDSA aligned, Catena-X ecosystem.
Beyond the niche: Principal Software Architect background β monolith-to-microservices transformation for a major Greek bank's core and e-banking systems, cybersecurity products (SOC orchestration), ERP, and payment systems. I take on complex, half-specified problems and get them right the first time, with minimal onboarding overhead.
Working languages: English (fluent), Greek (native)[, German (basic) β include only if true].
Available for remote engagements across the EU; well suited to subcontracting for consultancies needing senior EDC capacity on demand.
