What I do

Over a decade architecting, shipping, and scaling software — leading engineering teams across trading, automotive, and logistics, and modernizing how they build. Today my focus is cloud-native platforms, migrations, and data sovereignty.

Cloud platforms & DevOps

Kubernetes platforms built on infrastructure-as-code, GitOps delivery, CI/CD, and observability — so teams ship safely, repeatedly, and without heroics.

Cloud migration & data sovereignty

Moving workloads between clouds — or off the hyperscalers entirely — to meet data-governance, security, and residency requirements, without the downtime.

Backend & API architecture

The systems behind the product: federated GraphQL APIs, service integrations, gateways and auth, and data pipelines in Node.js, Go, and TypeScript.

Product & mobile development

Ideas to shipped products — full-stack web with React and Next.js, native iOS in Swift. Fast prototypes, real MVPs, releases that hold up.
