What I'm looking for

I'm open to remote work or relocation, and want to help teams build pragmatic, reliable, observable systems through AI automation, distributed backend architecture, developer tooling, and strong engineering practices.

At UserTesting, I spearheaded cross-team AI adoption and architected an Autonomous Background Agents platform for safe asynchronous agentic workflows and automated background tasks.

I've built, scaled, and maintained 20+ event-driven microservices powering real-time analytics and consumer dashboard features, using Python, Go, Clojure, Kafka, RabbitMQ, PostgreSQL, and Redis.

I led UserTesting's migration from AWS EC2 and Fargate to Kubernetes (EKS), and engineered GitOps-driven CI/CD pipelines for backend services and frontend applications to support zero-downtime deployments.

Previously, I built high-throughput enterprise data connectors and search pipelines at ONNA, introduced unified CI/CD and Docker adoption at Lodgify, and co-founded MESTR.io, where I help deliver legal-tech products and technical strategy for eDiscovery and responsible AI.
