Senior Software Engineer with 8+ years building production systems end-to-end, from data pipelines to user-facing apps. Currently a founding engineer on Boomi Event Streams, a managed pub/sub streaming platform built on Apache Pulsar, focused on multi-tenant topic and subscription management, dynamic routing, and the SDKs and tooling customers use to plug it into real workloads. Outside of work I ship indie software and hardware under hdbLabs.
