Self-Service Platform · 2019–2023

Daiteap — Multi-Cloud Management Platform

Daiteap gives engineering teams a unified UI and API to provision and manage Kubernetes clusters, VMs, and S3 storage across AWS, GCP, Azure, Alicloud, on-premise, and edge IoT devices. Environments are interconnected via encrypted WireGuard / IPSEC VPNs, so nodes across clouds communicate without public IPs.

Open Data Infrastructure · 2022–2023

GAIA-X Federation Services

CST built and deployed core federation microservices for the European GAIA-X ecosystem — including Principal Creation, Invitation, DID Management, and Claim Mapper services — running on Kubernetes with Helm-based CI/CD. Covered identity & trust, federated catalogs, and sovereign data exchange.

EU Horizon 2020 · 2021–2025

ALTERNATIVE

An EU-funded research platform for detecting cardiotoxicity of chemicals and industrial pollutants. CST built the cloud data platform that runs, stores, and serves ML models, and developed the data exchange portal using CKAN with custom OIDC/SSO, S3 storage, and JupyterHub integration for automated research workflows.
