Howdy, I'm Caleb

Senior Platform Engineer at Optum, where I help keep healthcare data streaming at scale.

I'm one of the deepest technical owners of a Kafka-as-a-Service platform: 1,000+ production nodes, 750+ clusters, five-nines reliability, zero customer data loss. I build the full stack - from Kubernetes operators in Go to self-service React UIs that let developers provision production-grade streaming infrastructure in minutes.


What I work with daily

  • Streaming: Kafka, WarpStream, Confluent, Schema Registry
  • Infrastructure: Kubernetes (custom operators, CRDs), Terraform, GKE, Docker
  • Languages: Go, TypeScript, Python, Bash
  • Frontend: React, Next.js, micro-frontend architecture
  • Observability: Prometheus, Grafana, Thanos, PagerDuty

What I care about

  • Building platforms that make the health system work better for everyone
  • Making infrastructure self-service so engineers can ship faster
  • Mentoring early-career engineers and making tech more accessible
  • Writing code every day - I'm a senior engineer who still ships production code daily

Right now

  • Working on cutting Kafka infrastructure costs by ~80% with WarpStream's diskless architecture
  • Open to collaborating on developer experience tooling, streaming infrastructure, or digital transformation initiatives

Ask me about

  • Running Kafka at enterprise scale without losing a single byte of customer data
  • Building self-service developer portals that engineers actually want to use
  • Migrating from on-prem to GCP (and why we chose it over Azure)

Elsewhere

  • IEEE-published researcher in NLP/sentiment analysis
  • Google Cloud Certified - Cloud Digital Leader
  • B.S. Software Engineering, St. Cloud State University
