Managed Proxmox clusters
Multi-node Proxmox VE design, shared storage, high-availability policy, upgrades, monitoring, and lifecycle support.
Choose the cloud layer you need
Start with one app or build the whole platform. Every scope includes explicit ownership, a backup plan, and documentation your team can use.
Standalone app deployments
Focused Docker or Coolify deployments for one application, with domains, TLS, backups, updates, and a clean handoff.
Nextcloud storage + apps
Managed files, photos, calendars, contacts, groupware, and approved Nextcloud apps on infrastructure you control.
TrueNAS storage + apps
ZFS-backed storage, snapshots, SMB or NFS shares, and Docker applications with separate, recoverable data sets.
YunoHost instance hosting
Lightweight Debian-based app hosting with domains, certificates, users, SSO, backups, and catalog applications.
OpenStack private clouds
OpenStack-based compute, networking, identity, and storage deployments sized for real private-cloud requirements.
Proxmox Community Scripts apps
Curated LXC and VM application installs from the community catalog, with source review, isolation, backups, and update planning.
Backup + recovery platforms
Proxmox Backup Server integration, retention policy, encrypted off-site copies, restore drills, and recovery runbooks.
K3s application clusters
Lightweight Kubernetes for edge, lab, and private workloads, from a single server to justified high availability.
How an engagement runs
1
Align on outcomes
Constraints, success metrics, and integration points - web, device firmware, or hardware - before writing code.
2
Build in thin slices
Iterate with visible increments: APIs, UI, tests, and telemetry so progress is always demonstrable.
3
Hand off cleanly
Deployment notes, runbooks, and knowledge transfer so your team owns the system confidently.
Quality
Design reviews that catch risk early
Structured reviews for firmware, web, and mechanical interfaces - so surprises surface in the spec, not in production.
Delivery
Shipping beats slide decks
Small vertical slices, measurable outcomes, and docs that the next engineer can run with. Built for long-term maintainability.
