I design and build the unglamorous layer everything else depends on — cloud infrastructure, storage and backup systems. At Qumulus I engineer and lead the team behind a managed private cloud in Go — now evolving on top of a managed Kubernetes platform. Around it, I've shipped mobile products in Flutter and full-stack platforms in TypeScript — from field-service SaaS to high-throughput image pipelines.
