Cloud Architect · Platform Engineer · Trainer

I build platforms that let teams ship faster and sleep better.

Kubernetes, GitOps, zero-trust security, and observability — from bare-metal labs to enterprise-scale Azure/AWS deployments.

About

25+ years building infrastructure — from single-rack servers to multi-cloud platforms.

I've worked in enterprise telecom, investment banking, SaaS startups, and consulting. Today I architect production-grade Kubernetes platforms, design GitOps workflows, and train engineering teams on cloud-native operations. When I'm not deploying Crossplane compositions, I'm writing tutorials or building open-source tools.

Let's build something together.

Looking for a cloud architect, platform engineering consultant, or trainer? I'd love to hear about your project.

Selected Work

Case studies from real projects.

Platform

Enterprise Zero-Trust Kubernetes Lab

Production-grade K8s with GitOps, SSO, Vault secrets, and full cluster rebuild in under 30 minutes.

Security

SSH Management with Keycloak

Centralized SSH access via Keycloak groups — no FreeIPA, no LDAP, instant revocation.

KeycloakSSHPAM

Automation

Azure Storage Policy Automation

K8s-native Python service reconciling blob access policies and rotating SAS tokens into Key Vault.

Developer Experience

Crossplane Self-Service Portal

Self-service UI abstracting Crossplane behind a role-based wizard. Developers provision infra without K8s knowledge.

Observability

AI Observability Agents

Non-invasive AI overlay on OTel → ClickHouse → Grafana for anomaly detection and LLM-powered incident reasoning.

Kubernetes

Building K8s Monitoring from Scratch

Prometheus, Alertmanager, Grafana — deployed with Helm and wired to real workloads.

Hands-on GitOps

GitOps with ArgoCD ApplicationSets

One ApplicationSet deploys any chart to any cluster — multi-env GitOps without duplication.

Hands-on Security

Zero-Trust K8s with OIDC

K8s API server integrated with OIDC — RBAC driven by identity provider group membership.

Hands-on Cloud

Crossplane Cloud Provisioning

Declarative multi-cloud infrastructure using Crossplane compositions and XRDs.

Hands-on Observability

Observability Pipeline: OTel → ClickHouse

Full telemetry pipeline — traces, metrics, logs via OpenTelemetry Collector into ClickHouse.

Hands-on AI Tooling

Engineering an AI Coding Workflow

A near-empty CLAUDE.md becomes a guarded, model-tiered pipeline — token audits, hooks, and a Makefile seam.
