AI infrastructure, platforms, and the systems that run them.

I am an AI infrastructure and platform engineer, and the founder of Systemics. I design and build the platforms underneath production AI: Kubernetes, GitOps, LLM serving, and the cost controls that keep them sustainable.

What I Look for When Reviewing an AI Platform Architecture

Six areas decide whether an AI platform survives contact with production: tenancy, egress control, model routing, observability, kill-switches, and IaC coverage. The questions, what good looks like, and what I usually find.

A FinOps Loop for AI Workloads That Survives Past the First Cleanup

Most AI cost programs are one-time cleanups and the bill drifts back within a quarter. The weekly loop I run instead: attribution, anomaly detection on billing data, ranked levers, budgets as code.

Running Temporal Workers on Kubernetes Without Dropping Activities

Temporal workers look like stateless services and are not. The deployment topology, rollout mechanics, and schedule management that survive production, plus the failures that actually page you.

Guide

AI Platform Readiness: A Self-Assessment Across Nine Dimensions

Rate your AI platform across strategy, data, sovereignty, technology, economics, MLOps, identity, compliance, and skills. Four rungs per dimension, with the evidence that separates a claim from a fact.

LLM Cost Levers, Ranked by Typical Impact

The five levers that move an LLM bill, honest savings ranges, a routing table template, and the breakeven math for when fine-tuning beats prompting.

Kubernetes GitOps Checklist: ArgoCD, DNS, Secrets, Rollouts

The checklist I run before calling a cluster GitOps-managed: app-of-apps layout, external-dns, secrets handling, progressive rollout gates, and rollback drills that include the ugly cases.

About

AI infrastructure and platform engineer. Founder of Systemics.

I build the platforms underneath production AI: Kubernetes foundations, GitOps delivery, LLM serving and RAG pipelines, and the cost controls that keep all of it sustainable. As founder of Systemics I design sovereign AI infrastructure for organizations that cannot hand their data to someone else's cloud.

Founder, Systemics

2024 - Present

Sovereign AI infrastructure for regulated industries: readiness assessments, private LLM deployments, and fractional platform architecture.
