Platform engineering
end to end

From bare metal to production. We handle the complexity so your team can ship.

01

Kubernetes Platforms

Production-grade clusters on Talos Linux. Immutable, API-driven OS with no SSH surface. BGP routing via FRRouting for bare-metal load balancing, LoxiLB for service exposure, Ceph and LINSTOR for persistent storage.

  • Talos Linux
  • FRRouting / BGP
  • Ceph
  • LINSTOR
02

GitOps Delivery

Everything in Git. Flux CD for continuous reconciliation, Helm for packaging, SOPS for encrypted secrets. Zero manual kubectl apply.

  • Flux CD
  • Helm
  • SOPS
  • GitLab CI
03

Cloud Infrastructure

Crossplane-driven cloud resources as Kubernetes manifests. Terraform for bootstrapping. Full IaC, no click-ops, git-auditable everything. Ceph for distributed storage, Percona MySQL and CloudNativePG for production-grade databases. Works across AWS, GCP, Azure, and Hetzner.

  • Crossplane
  • Ceph
  • Percona MySQL
  • Terraform
04

Observability

Full-stack metrics, logs, and traces. VictoriaMetrics cluster for long-term storage, Grafana Alloy as unified collector, Loki for logs. Alerting that fires when it matters.

  • VictoriaMetrics
  • Grafana
  • Alloy
  • Loki
05

Security & Access

Zero-trust access via Teleport, mTLS between all services via cert-manager, CrowdSec for threat intelligence and adaptive banning, SOPS with age for encrypted secrets in Git. Security baked in, not bolted on.

  • Teleport
  • mTLS
  • CrowdSec
  • SOPS / age
06

ML & AI Infrastructure

GPU-accelerated inference and training pipelines on Kubernetes. Model serving via vLLM and Ollama, RAG systems with pgvector and Redis Streams, automated training and deployment workflows. On-prem, private, no vendor lock-in.

  • vLLM / Ollama
  • pgvector
  • Argo Workflows
  • NVIDIA GPU

Principles, not just tools

01

Everything is code

If it's not in Git, it doesn't exist. Infrastructure, secrets, policies, runbooks — all version-controlled, all reviewable.

02

Immutable by default

Talos Linux, container images, Helm releases. We don't patch running systems — we replace them. Reproducible rebuilds every time.

03

Observe everything

You can't fix what you can't see. Every service ships with metrics, structured logs, and traces before it goes to production.

04

Automate the toil

If you're doing it manually more than twice, it becomes a controller, a webhook, or a CI pipeline. Human time is for hard problems.

05

Cloud-agnostic by design

We build cloud-agnostic infrastructure so workloads can move between cloud providers or on-prem environments with minimal operational cost and friction.

06

Security by design

We build secure environments alongside the infrastructure itself, not as an afterthought. Access, secrets, policies, and controls are designed in from day one.

Ready to build something reliable?

Whether you're starting from bare metal or migrating a legacy system to cloud-native, we can help. Let's talk about your infrastructure.
