No client list yet, but more than words: my own infrastructure, built and documented like a client project. Each study is a PDF to read up on, with an architecture diagram.
A self-hosted server platform with 35+ VMs and containers: storage design, resource isolation and encrypted off-site backups with a documented, tested restore. Operated like a production environment.
A multi-tier segmented network (VLANs) with a firewall rule set and VPN access for secure remote work. Least-privilege and segmentation: each segment only sees what it needs. Planned, implemented, documented.
A multi-tenant backend with row-level security in PostgreSQL, domain-driven design and an event architecture. Shows how to isolate several clients securely on one platform. Anonymized study.
