INDEPENDENT PLATFORM & DEVOPS ENGINEER

Built for
production.

I’m Stephano. I build cloud platforms, automate delivery, and keep production running—from core services to AI systems.

EXPERIENCE IN PRODUCTION

Selected work.

PRODUCTION AI

ai-coustics

Kept production serving through releases and infrastructure changes without downtime. Built GitHub Actions workflows, an AI harness, and custom Kubernetes tools for delivery and operations.

I built and operated the platform behind real-time speech enhancement, spanning cloud architecture, Kubernetes, and SRE. Reviewed pipelines and controlled model rollouts gave the team a repeatable path to production. My work also covered GPU capacity, inference observability, and rollback paths—keeping the running service in view while improving how the team shipped.

PLATFORM ARCHITECTURE

Volkswagen

Architected and implemented the Kubernetes and container orchestration platform as a core engineer in a small team. Infrastructure supporting 200+ applications and millions of connected vehicles.

Working through Storm Reply, I covered the platform from cloud foundations and cluster architecture to deployment automation and operations. It spanned AWS and Azure, dozens of clusters, and 500–1,000 autoscaled nodes. I also owned SRE work: service-level objectives, on-call, incident response, critical etcd fixes, and upstream contributions to WeaveNet CNI.

CRITICAL INFRASTRUCTURE

DFS

Automated infrastructure, built Kubernetes clusters, and provisioned and managed VMs. Reviewed changes and controlled delivery for Germany’s national air navigation service provider.

I connected the infrastructure lifecycle across private-cloud and data-center environments using Terraform, Ansible, and GitLab CI. The work included repeatable cluster bootstrapping, VM management, and clearly separated environments. Changes moved through reviewed pipelines and defined promotion steps, supporting teams responsible for flight control, airport tower systems, and operations.

Signavio

Introduced and operated Kubernetes across AWS and Azure: 500+ nodes across three continents.

Engineering details — Signavio

In a small infrastructure team, I supported customer growth across North America, Europe, and Asia. I built a ChatOps tool for self-service deployments, later open-sourced and adopted by other companies, and established observability, GitOps, and SRE practices.

Selected freelance and employed experience. Volkswagen engagement through Storm Reply.

Also building AgentShield: a Go security scanner for AI agent configurations and CI/CD pipelines.

How I can help.

Platform Engineering

Kubernetes platforms, cloud architecture, and infrastructure as code. Repeatable environments and self-service delivery that give your engineers a clear path from code to production.

DevOps & SRE

Reliable releases, useful observability, and hands-on operations. CI/CD, service-level objectives, and incident response to keep your software shipping and your services healthy.

MLOps & AI Platforms

Model serving, GPU infrastructure, and AI tooling. Bring trained models and agent workflows into production with controlled rollouts, monitoring, and the operating practices they need.

Building systems since 2006. Still hands-on.

I started with operating systems and network appliances. Since then, I’ve built platforms and taken the call when production broke. I stay close to the code and make sure your team can own what we build.

building next?

Tell me what you’re building, what’s getting in the way, and your timeline. We’ll find a useful first step.
