Systems that hold up in production.

I help engineering teams get things into production and keep them there — Kubernetes platforms, LLM inference, and cloud foundations on Azure and AWS.

Hands-on engineering for teams running mission-critical workloads.

What I help with

Three practices, one job: getting systems into production and keeping them there. I work hands-on and embedded with your team — from architecture to day-2 operations, across Kubernetes, AI and cloud.

Kubernetes & Platform Engineering

Cluster design, hardening and day-2 operations you can actually sleep through.

  • Cluster design, hardening & multi-tenancy
  • GitOps delivery with Argo CD & Flux
  • Internal developer platforms & golden paths
  • SLOs, observability & incident response
  • Upgrades & day-2 runbooks

AI in Production

Everything between a working prototype and an LLM system you can run, trust and afford.

  • Inference serving & GPU autoscaling (vLLM, Triton)
  • LLM gateways, routing & cost caps (LiteLLM)
  • Evals, tracing & prompt management (Langfuse)
  • Guardrails, PII redaction & output sanitization
  • RAG pipelines & agent runtimes (LangGraph, MCP)

Cloud DevOps — Azure & AWS

Cloud foundations, infrastructure as code and delivery pipelines — built to hand over.

  • Landing zones & subscription/account governance
  • Terraform, Bicep & infrastructure as code
  • CI/CD with Azure DevOps & GitHub Actions
  • Identity, networking & security baselines
  • FinOps, right-sizing & cost visibility

From commit to production

The delivery pipeline I help teams build and operate — automated, observable and GitOps-driven end to end.

  1. 1

    Assess

    A focused review of your platform, delivery flow and cost — with a clear, prioritized roadmap.

  2. 2

    Implement

    I build alongside your team: clusters, pipelines and guardrails, shipped incrementally.

  3. 3

    Enable

    Runbooks, docs and pairing so your team owns it confidently after I leave.

The engineer behind tupevo

I’m Stefan Krempel — a platform engineer and the founder of tupevo. For over a decade I’ve designed, built and operated cloud-native infrastructure for startups and enterprises, from a first cluster to platforms serving millions of users.

tupevo is my independent studio. I take on a small number of consulting engagements at a time and channel what I learn into the products we build. You work directly with me — no account managers, no hand-offs.

This very site runs on the stack I recommend: Kubernetes, GitOps with Argo CD, and a privacy-first, cookieless toolchain.
