At AlgoMinds GmbH, I shaped the technical direction for DevSpells and a Siemens Energy Control System. I designed a pipeline for 1M MQTT messages/sec from Bosch Rexroth IoT devices and owned its data transport and storage layer end to end.
At Nyris GmbH, I architected a Kafka-based Actor Model data orchestrator that increased throughput from 18M to 1B messages per month. I also led a TDengine reporting system that ingested 1B rows in 10 minutes.
At CELUS (Contunity GmbH), I defined the client-facing app architecture, led the Angular-to-React migration, and built internal developer tools. The work included an Express/TypeScript gateway and Terraform and Ansible automation for ephemeral EC2 development machines.
Earlier, at UNIT23, I led a five-engineer team through a full-stack migration from PHP/Ember to React and Node.js. I also worked on web and mobile products for clients including Ace Hardware and Epicor, and contribute to open-source projects including KurzSharp and Nyris.Crdt.
